The product standard only contains minimum requirements. Attention is drawn to the fact that appliance specifications might contain requirements additional to or deviating from those specified in the relevant product standards.

Please be aware that the specifications nominal value used in the German part of the Schurter catalogue and the data sheets, is synonymous with rated value.

The difference between these two values is a pure matter of definition. In order to avoid any unnecessary complications we will continue to use the specifications nominal value.

CE marking is the only marking which indicates that a product conforms to the relevant EU-directive.

This means that the CE-mark is no quality or standard conformity mark but only an administration mark.

SCHURTER products are covered by the low voltage directives 72/23/EEC and 93/68/EEC. Those are valid for equipment and appliances with rated voltage values between AC 50 V to AC 1000 V as well as DC 75 V to DC 1500 V.

The CE marking of SCHURTER parts will be found on the label of the smallest packing unit. On request we will submitt a CE conformity statement for each component. CE conformity statements and approvals can also be retrieved from the internet under www.schurter.com.

National testing institutions are testing according to national and international standards or other generally recognized rules of technology. Their certification/approval-marks confirm the observance of the safety requirements which electric appliances must fulfil.

Approvals

National approvals

In addition to the combined UL/CSA approvals, most of the SCHURTER components are also approved by one of the European certification bodies like VDE (Germany), Electrosuisse (Switzerland) or SEMKO (Sweden). The safety testing of all these European certification bodies are based on the commen European safety standards. With the harmonisation effort in Europe, the different national European certification bodies have lost their importance and SCHURTER has decided to maintain only one European approval (e.g. VDE, SEV or SEMKO) in future. The others will not be renewed once they have expired.

Because UL and CSA are not members of the CENELEC, the standards of UL and CSA are not harmonised yet with the European standards. However, UL and CSA are trying to harmonize their standards with each other. Where possible, SCHURTER will apply for the combined cULus or cURus approval.

Further to development in Asia, SCHURTER has obtained national approvals from China, Japan and Korea.

Information about approvals

SCHURTER products are certified according to EN / IEC standards and carry country specific approvals in Europe.

During the last few years European countries made much effort to reduce their approval marks to one generally accepted mark. The ENEC approval mark replaces (wherever possible) the previous approval mark. The ENEC mark is offered by all national certification bodies that signed for the European certification agreement (CCA)*.

SCHURTER decided to reduce the variety of European approval marks. For new approbations of SCHURTER parts only the ENEC will be mentioned in the future:

Approvals for the US and Canada are according to the UL and CSA standards:

As UL and CSA are not a member of CENELEC these two are not according to the European approval marks. Wherever possible SCHURTER want to acquire the combined cULus approval mark:

Since Aug. 1^st. 2003 the Chinese approval mark is required for a lot of products to import to China. SCHURTER strives to get the approvals for the concerned products. For not testable products we offer an import certificate (free of CCC).

Standards IEC 60529; EN 60529 and DIN 40050

Scope

These standards apply to the classification of degrees of protection provided by enclosures for electrical equipment with a rated voltage not exceeding 72.5 kV.

Object

The object of these standards is to give:

a) Definitions for degrees of protection provided by enclosures of electrical equipment as regards:

1. Protection of persons against access to hazardous parts inside the enclosure

2. Protection of the equipment inside the enclosure against ingress of solid foreign objects

3. Protection of the equipment inside the enclosure against harmful effects due to the ingress of water.

b) Designations for these degrees of protection.

c) Requirements for each designation.

d) Tests to be performed to verify that the enclosure meets the requirements of these standards.

Designations

The degree of protection provided by an enclosure is indicated by the IP code.

Elements of the IP code and their meanings

A brief description of the IP code elements is given in the following table.

1. Protection against direct and indirect contact – general terms

The protection against electric shock on electric equipment as well as their components are divided into the following parts:

¹⁾ Accessible, conductive part, which is not conductive normally but which may be conductive due to a failure.

2. Protection against direct contact with live parts e.g. of a fuseholder

The data sheets of the relevant components inform about the taken measures.

3. Protection against indirect contact

Measures for the protection against indirect contact on electrical equipment are defined according to IEC 61140 by the 4 protection classes 0, I, II, III. Each protection class includes two protection measures. Even if one of these measures should fail, no electric shocks will occur.

Appliance couplers approved according IEC 60320 are designed as two pole appliance couplers for alternate current with or without protective conductor with a rated voltage of 250 V and a rated current of 16A for technical application that are desired for interconnection to flexible cords of electrical equipment for power supply of 50Hz or 60Hz.

Appliance couplers according mentioned standard are suitable for operation under environmental temperatures of normally 25° C and do not have to exceed 35° C.

Appliance couplers are designed for use without especial moisture protection. So the design of the appliance needs to assure ingress protection if it is designed to be used under these circumstances.

Following figures need to be respected in order to meet standard IEC 60320:

The appliance couplers are separated according the maximum operation temperature at the base of the connector pin:

Their outlines are coded in a way, that appliance couplers for hot conditions may also be used under cold conditions, and appliance couplers for very hot conditions may also be used under cold or hot conditions.

The appliance couplers are separated according the categories of equipment:

Appliance couplers will be additionally separated according the connection method to a flexible cord:

Appliance couplers, interconnection couplers and power plugs are developed and manufactured in accordance with national and international standards. These standards are issued in order to create a general consensus on the basic dimensions and safety goals of the appliance couplers. Following this approach, safety has been achieved, in the overwhelming majority of cases, when combining components. While the design of power plug systems is governed by the relevant national standards, appliance couplers follow the IEC 60320 standard, including its subsections.

The power supply of various electrical appliances follows country-specific requirements in terms of voltage and current. It is therefore practical for international appliance manufacturers to use IEC appliance couplers and interconnection couplers for their respective appliances’ power supply. SCHURTER, i.e. its Gerätestecker strategic division, provides a wide range of products for such purposes. In order to ensure full compliance with the given standards, SCHURTER products are tested by independent testing organizations (See ).

Two-pole AC-only appliance couplers, with or without earthing contact, rated for voltages up to 250VAC and nominal currents of up to 16A, used for connecting a flexible power supply cord to electrical appliances or other electrical installations at 50 or 60Hz (cf. IEC 60320-1).

Two-pole AC-only interconnection couplers, with or without earthing contact, rated for voltages up to 250VAC and nominal currents of up to 16A, used for interconnecting the power supply and appliances or installations at 50Hz or 60Hz (cf. IEC 60320-2-2 ).

The requirements placed on connectors are contingent on the maximum temperature of the corresponding appliance inlets, i.e.:

‘Cold condition’ appliance inlets may not be used in appliances with exterior parts whose temperature increase can exceed 75K and which, when used properly, can come into contact with the movable power cord.

According to IEC 60320, the following nominal currents apply: 2.5A / 6A / 10A /16A. The nominal current ratings of SCHURTER’s components are based on the relevant approval standards which may differ from one country to another (see Approval Bodies). The table below shows the differences between the IEC’s nominal current ratings and those approved by VDE, UL and CSA (SCHURTER reference components).

IEC 60320, to prevent improper use, provides for contour coding for the nominal currents listed above.

With regard to protection against direct contact, the appliance couplers are categorized as follows:

See detailed explanations on Electric Shock Protection

Appliance couplers in compliance with the present standards are designed to connect appliances without special protection against humidity (see IP Protection Class). Appliances whose operation, when used properly, may involve overflowing liquids or dust emissions must themselves be protected against humidity. IEC standard 60320-2-3 provides that the power supply’s IP protection rating must be at least identical to that of the appliance.

Special designs may also become necessary in environments involving special conditions (e.g. on ships or in motor vehicles) and in dangerous locations (e.g. involving explosives).

The suitable connection options for appliance couplers are listed below. The appliance couplers’ contours are coded (type, symbol) so as to allow a ‘hot condition’ connector to fit into a ‘cold condition’ appliance inlet, but not vice versa. Important note: The appliance inlet nominal current rating must be at least identical to that of the appliance!

Combinations according to IEC 60320-1: • intended, □ possible

The available product combinations can be selected under ‘Mating IEC Connectors’.

The suitable connection options for interconnection couplers are listed below. The regulatory framework applicable here is identical to that governing IEC 60320-1.

The available product combinations can be selected under ‘Mating IEC Connectors’.

Combinations according to IEC 60320-2-2: • intended, □ possible

On standard, non-reversible appliance inlets/outlets, the contacts, when viewing the engagement surfaces from above, must be configured as follows:

The illustration below shows a possible component configuration, properly naming the various components which will be explained in detail further down, including the distinguishing characteristics.

Appliance coupler means devices for connecting a flexible power cord to an appliance or another installation. You will find a product overview under ‘Gerätestecker’. Appliance couplers essentially comprise the following components:

Interconnection cords means structural units consisting of a flexible cord fitted with a plug and a connector built for interconnecting or disconnecting any appliance or installation with/from any other appliance or installation by means of a power cord. You will find a product overview under ‘Cord Sets’.

Rewireable plugs and connectors means structural units built to allow the flexible cord to be exchanged/replaced, colloquially referred to as ‘cord plugs/connectors’. You will find a product overview under ‘Cord Connectors’. That overview also includes the power plugs available.

Configurator | Webselector Chart | Mating Connector

Non-rewireable plugs and connectors means structural units which, in contrast to removable plug and connectors, are built to form an integrated, inseparable whole with the flexible cord. You will find a product overview under ‘Cord Sets’.

Means power entry modules (PEM), i.e. modules including different functional elements, such as:

The advantages of PEM over individual components include:

You will find a detailed product overview under ‘Power Entry Modules without Filter’ and ‘Power Entry Modules with Filter’.

The IEC appliance inlets and outlets correspond to the individual components already presented in compliance with the IEC’s appliance couplers standards. You will find a detailed product overview under ‘appliance inlets/outlets’.

A specific approach is the shuttered outlet that protects unintended contact with life parts by movable protection shutters. They will be moved away by the insertion of the plug connector. The product is herewith ideally suitable to be used in applications to be used by children.

A special design is the protected outlet. The individual connections of a distribution unit can be limited by its power consumption by using a fuse-link. The optional neon indicates the correct operation stage of the power line.

Configurator | Webselector Chart | Mating Connector

Switches can be built both as 1-pole (phase conductor disconnection) and 2-pole (phase and neutral conductor disconnection) units to ensure compliance with the relevant power supply standards. As a matter of principle, high-quality products are used which meet the current requirements and which are well within the given nominal current boundaries as defined by the IEC 60320 standard on appliance couplers.

Remote actuator technology

The remote actuator cable assembly consists of a wire cable inside of a plastic insulated spiral wire casing. Identifying a proper routing of the cable assembly is important. Deviations from line to line placement will require bends in the cable with resulting losses in the overall assembly. These inefficiencies show up as friction losses and lost motion. Frictional losses are increases in actuation force due to losses in the assembly. Lost motion is an undesirable difference between the input end of the assembly and the output end. The principle element of lost motion is backlash and deflection. Backlash is caused by the wire cable moving inside the casing with the change in direction of motion. It is the function of clearance between the wire cable and casing, plus the number of degrees of bend in the cable assembly. Deflection of the cable assembly, while usually low, can be minimized by anchoring the casing. This is especially true in those applications of cable assemblies with long lengths and/or large degrees of bend in the system All of these losses and resulting inefficiencies can be reduced by the equipment designer through minimizing the total degress of bend in the assembly. Because of the number of variables effecting proper operation of any remotely actuated switch assembly, it is important that the ordering instructions be used to determine proper cable length and to provide samples for customer approval.

Consult figure for minimum information required to describe cable assembly application.

Protection against electric shock (against direct contact with live parts) for fuseholders

The assessment of the protection against electric shock assumes that the fuseholder is properly assembled, installed and operated as in normal use, e.g. on the front panel of the equipment. IEC 60127-6 and EN 60127-6 divides into three categories:

Extra-safe handling with SCHURTER power entry modules

Protection against contact with live parts is an important aspect when dealing with electrical connecting devices. Both your customers and your servicing engineers will appreciate the greatest possible protection against accidental contact with live parts – something which can easily happen as a result of inappropriate use, or during servicing or repair work.

In particular, our “shock-safe�?, “extra-safe fuse-drawers�? and “protective covers�? precautions are effective ways of protecting against accidental contact when using the power entry modules.

Example: Power entry module with fuseholder, shocksafe category PC2

The extra-safe versions of shock-safe power entry modules are now available.

They are thus also able to satisfy requirements of the following standard: IEC 60601-1 (medical equipments).

Influencing factors

The design engineer of electrical equipment is responsible for its safety and functioning to humans, animals and real values. Above all, it is his task to make sure that the state of the art as well as the valid national and international standards and regulations be observed.

In view of the safety of electrical equipment the selection of the most suitable fuseholder is of great importance. Among other parameters, one has to make sure that the maximum admissible power acceptances and temperatures defined by the manufacturer are followed. Differing definitions and requirements in the most important standards for fuse-links and fuseholders are time and again origin for the incorrect selection of fuseholders.

To equate the rated current of a fuse-link with the rated current of the fuseholder, may, especially at higher currents, cause high, not admissible temperatures, when the influence of the power dissipation in the contacts of the fuseholder was not taken into consideration.

For a correct selection the following influence factors depending on the application and mounting method, have to be followed:

Rated current of a fuseholder

The value of current assigned by the manufacturer of the fuseholder and to which the rated power acceptance is referred.

Rated power dissipation of the fuse-link

(power dissipation at rated current)

See sep. catalogue “fuses�?.

Rated power acceptance and admissible temperatures of a fuseholder

The rated power acceptance of a fuseholder is determined by a standardised testing procedure according to IEC 60127-6. It is intended to be the power dissipation caused by the inserted dummy fuse-link at the rated current of the fuseholder and at an ambient air temperature of T_A1= T_A2 = 23 °C (over a long period). During this test the following temperatures must not be exceeded on the surface of the fuseholder:

Illustration of temperatures experienced

Correlation between operating current I, ambient air temperature T_A1 and the power acceptance P_h of the fuseholder

This correlation is demonstrated by derating curves.

Example of a derating curve

I =operating current of the fuseholder

In =rated current of the fuseholder

The derating curves demonstrate the admissible power acceptance of a fuseholder depending on the ambient air temperature T_A1 for the following fuseholder operating currents: I << I_n, I = 0,7 · I_n and I = 1,0 · I_n. This power acceptance corresponds to the max. admissible power dissipation of a fuse-link.

A calculation example can be looked up in the technical information for fuses.

Operating appliances in international markets requires taking into account the country-specific power supply systems. An appliance capable of operating under different voltages must allow the user to select and display such voltages. SCHURTER provides three differently configurable voltage selectors for such purposes.

Voltage Selector

Series-parallel connection

Allows the user to achieve a multitude of line voltages with one transformer with three primary windings and one secondary winding.

Step switch

This circuit allows the user to select up to four primary voltages.

Jumper

The easiest way to set only two voltages is by using a jumper.

Ensuring the electromagnetic compliance (EMC) of specific appliances may necessitate the use of filter components, colloquially referred to as inlet filters or IEC inlet filters. Filters may also be used in addition to the PEM described above. You will find a detailed product overview under 'Power Entry Modules with Filter'.

Means components used to, for instance, supply a multitude of appliances equipped with IEC appliance couplers with power from only one country-specific power supply cord via several interconnection cords. You will find a detailed product overview under ‘Distribution Units’.

Since, due to the lack of standards, distribution units have only limited UL and VDE approval, modular solutions assembled from approved individual components (inlets/outlets) have been made available. The applicable nominal voltage, the cord retainers and the necessary conductor cross-sectional areas (gauge) can be specifically selected depending on the relevant application area.

Protective caps or covers for appliance inlets and power entry modules prevent inadvertent contact with the live parts on the appliance’s interior. They are made from flexible plastic and can be pushed onto the components from the rear. Compatibility information on the various types of covers is available in a relevant data sheet.

Cord retaining clamps ensure firm push-on connections. The compatibility of the selected appliance couplers is imperative for reliable protection. You will find a detailed product overview on cord retaining clamps in the chapter "pullout prevention on pluggable power supplies".

The power supply cords and the interconnection cords are based on standardized individual components (connectors, power plugs or appliance outlets and various power cord types).

The individual conductors of the flexible cords are, depending on their use in power supply cords and interconnection cords, divided into IEC-compliant nominal current classes and therefore require a length-dependent minimum nominal cross-sectional area (gauge).

These cross-sectional areas are likewise subdivided, in compliance with American standards, into classes according to AWG. Hence, cord configurations can be made on the basis of the conductor cross-sectional areas and the AWG classes.

The various cord types have been internationally harmonized using the following configuration key:

Definition of cord length for complete power supply cords (plug and connector)

According to EN 60320-1 §21, the lengths of the power supply cord is defined by the visible length of the cord, form the bushing to the bushing. The length SL is a dimension which is necessary for the manufacturing process and results from the length of the cord and its components.

Definition of cord lengths for open-end power supply cords

The length of the open-end cord is defined as the length of the cord from the bushing to the cut (if there are several conductors of different length, the longest individual conductor (ML) is used for establishing the length of the cord). The lenght SL is a dimension which is necessary for the manufactoring process and results from the lenght of the cord and its components. In order to properly treat the open end, we need the following information from you:

(When simply stripping the conductor, the stripped insulation is usually left on the conductor in order to keep the stranded wire from becoming frayed.)

Stockpiling and manufacturing reasons, the cord length per injection-molded power plug or connector may vary by +/- 60mm.

Different applications require different approaches to the optimal mounting of appliance inlets and outlets, taking into account both minimal dimensions and customer-specific assembly methods, e.g. the module design possibilities that allow electrical testing even before mounting.

Mounting appliance inlets and outlets into front panels is possible both from the front (exterior of the appliance’s mounting board) and from the rear (interior of the appliance’s mounting board) to respond to different customer-specific assembly scenarios.

Usually, the appliance couplers are, together with other control components, mounted (and then wired) from the front into the appliance’s housing. Under certain circumstances it is practical to test the entire electrical unit before mounting. In such cases it is imperative that the appliance coupler be mounted from the rear.

The mounting method describes the procedure of mounting the appliance coupler onto the mounting board.

Snap-in mounting

Snap-in mounting facilitates the insertion of the appliance coupler into the properly prepared panel cutout. Mounting is done by locking snap-in lugs or snap locks (parts of the supplied component) into place. Usually, snap-in mounting is done from the front.

We distinguish between three categories:

One-step snap lock

This snap lock fits perfectly when mounted onto a board with the same thickness as specified in the relevant data sheet.

Incremental snap lock

This snap lock fits perfectly when mounted onto boards with the same respective thicknesses as specified in the data sheet. Hence one product can be used for different housing systems, provided that their panel thicknesses match the snap lock’s specs.

Universal snap lock

Universal snap locks do not require a specific panel thickness. They fit perfectly when mounted onto boards with any thickness within the range specified in the relevant data sheet.

Screw-on mounting

Screw-on mounting is largely independent from panel thickness and ensures better firmness. Mounting can be done both from the front and the rear; however, in contrast to snap-in mounting, this method requires screws and possibly nuts as well (which are not included, unless specified otherwise). For safe mounting, the specified screw tightening torques must be observed, in order to prevent d amaging the component while ensuring secure fastening.

The standard version is mounted using countersunk head screws. Depending on the information in the data sheet, other product types, i.e. with a through hole or flat head machine screws, may be used.

A special type of screw-on mounting appliance coupler comes with the tapped holes for screw-on mounting already in place on the mounting flange, thus reducing the number of components which, in specific cases, may also ensure the product’s tightness to the mounting board (see 5707)

Sandwich mounting

Sandwich mounting makes it possible to mount appliance couplers without the need for additional components. Mounting can be done both from the front and the rear, as specified in the relevant data sheet.

Mounting instructions

Rivet mounting

Rivet mounting is essentially identical to screw-on mounting when using the mounting holes as through holes or using flat head machine screws with the corresponding dimensions as specified in the relevant data sheet.

The mounting position indicates, with regard to the connector pin’s orientation, on what side the mounting elements are, treating snap-in and screw-on positions identically.

The appliance couplers’ terminals refer to the contacts on the appliance’s interior, designed according to the customers’ individual needs. We distinguish between the following types:

The solder tab is a plated metal tongue for fastening a connecting stranded wire by soldering it on. The solder tabs’ geometry may vary. The corresponding connection dimensions are listed in the relevant data sheet.

The PCB connector is a plated metal contact for soldering onto a contact conductor’s contact point on a PCB. We basically distinguish between Through-Hole Technology (THT) and Surface Mount Technology (SMT). The connections’ geometry is specified in the relevant data sheet.

Quick connect, push-on or blade terminals feature metal blades with standardized dimensions. They are also referred to as faston terminals, typically measuring 4.8 x 0.,8 mm, 6.3 x 0.,8 mm. The terminal dimensions are specified in the relevant data sheet. Correspondingly, the connecting stranded wires must be fitted with flat pin bushings of identical dimensions.

In IDC terminals respectively connectors (IDC meaning ‘Insulation Displacement Connector’), the strands of the connecting stranded wire or wire are, without prior preparation of the power cord, pushed onto the insulation cutting terminal, the terminal cutting the insulation open and the clamping connection fastening the stranded wire or wire ensuring the electrical connection. In order to ensure a perfect connection, the conductors’ cross-sectional areas as specified in the relevant data sheet must be observed.

Screw-on terminals are simple clamp fasteners using stud screws for fastening the connecting stranded wires.

Power supply is also possible without using additional cabling components, because appliance couplers are available pre-fitted with the connecting stranded wires. Stranded wires pre-fitted with plugs are also available upon request for mounting the power entry module into the target appliance without the need for any further process steps.

The wire harness service includes several types of ready to install wires, cables or wire harnesses with custom specific end terminal connections. The SCHURTER products such as IEC 320 connectors, power entry modules or filter products with quick connect, solder or screw on terminals can be assembled with above custom specific interconnection solutions.

1) SCHURTER connector type, 2) Connector terminals, 3) Receptacles, 4) Wire-type and colour, 5) Wire length, 6) Wire end terminal

As power entry elements or so-called PEM (Abbreviation for Power Entry Module) refer to items that contain, in addition to a pure plug-in device more functional elements, such as switch, circuit breaker, fuse holder, voltage selector.

EMC connectors and PEMs are IEC60320 inlets equipped with an EMC filter function and provide the necessary attenuation to meet in the stringent EMC requirements in the various application fields.

The above-mentioned components with various interconnection terminal types such as quick connect, solder or screw-on terminals are available with wire harness (for details see catalogue data sheet respectively the WEB selector).

The quick connect or fast-on terminals correspond to metal mounting clamps with standard dimensions, typically in the size of 4.8 x 0.8 mm, 6.3 x 0.8 mm. The dimensions of the connections are specified in the product data sheet of the connector or power entry module component. Accordingly, the flexible wire end needs to be assembled by a quick connect terminal of a female type with the same dimensions.

Solder connections are made of a coated metal tab for attaching a flexible wire by soldering. The soldering terminals may be of geometrically different characteristics. The dimensions of the solder terminals are given in the product catalogue data sheet.

Screw on terminals are clamp fixtures, connecting flexble wires using threaded pins or wholes with screws or nuts.

Wires used will be available as AWG18, AWG16, AWG14 cables according UL3266 in standard colours such as brown, black, bright blue, yellow-green and customized lengths.

(AWG stands for American Wire Gauge and is a coding for wire diameter, which is mainly used in North America. It features electric lines of stranded and solid wire and is used mainly in electrical engineering to describe the cross section of wires.)

The connections of the wire harness are determined by the selected Power Entry Module part. At the free end the flexible wires are individually assembled to customers' specifications.

Standard connections are provided as for example quick connect terminals 6.3 mm or 4.8 mm, ring terminals M4 or individual leads. Connections are possible with a full insulation, partly insulated or without.

To avoid the danger of accidentally unplugging a power cable from the device, several various types of pullout preventers are offered.

The V-Lock locking system can be used for 10 A and 16 A power inlets and connectors according to IEC 60320. This system works in such a way that there is a pin in the socket, interlocking with a notch in the plug and thus prevents an unintentional pullout of the power cable.

The locking is released by pressing on the releasing lever. This lever is easily detected by its bright yellow colour and thus distinguishes this system from existing power cable connections.

V-Lock pullout prevention system prevents accidentally pulling out power cables in a simple manner

Another type of pullout prevention on pluggable power supplies are retaining clips, which are mounted to the device plug and are pressed over the cord connector. Regardless of device plug type and the multitude of electrical sockets shapes, the correct selection of retaining clip must be made. This retaining clip system ensures that the plug is correct, i.e. adequately deep, inserted to avoid the danger of accidentally unplugging a power cable from the device.

A special sealing kit increases the IP protection to the device including the protection of the plug connection. This additional safeguard assures a certain protection against the unwanted entry of moisture and dust when working with power cables that are plugged in. The power supply seal is produced with an inlet gasket around the plug pin. When plugged into a cable socket, the seal prevents liquids and dust on the plug pins from reaching live parts, as well as from ending up in the socket.

The device plug with inlet gasket is approved by IEC and UL. To be sure that the cord connector really is properly and completely plugged in, and to additionally protect the connection from accidentally being unplugged, device plugs should be equipped with a pullout preventer. Only in this way can an IP-protected connection be secured, regardless of operating conditions.

Plug connection with retaining clip and additional sealing kit

The SCHURTER power mains plugs, power interconnection plugs, and cord connectors displayed in this catalogue are designed and manufactured in accordance with national and international standards. These standard have been published to create a worldwide understanding about basic dimensions and safety targets of coupler systems. This way a high degree of compatibility of components of different origins has been achived.

Power mains plugs are designed to the relevant national standards whereas appliance couplers meet the standards as followes: DIN VDE 0625, EN 60320, IEC320 „Appliance couplers for household and similar general purposes, Part 2: interconnection couplers for household and similar equipment“.

For different reasons you might consider or be forced to use a coupler system on your application that does not mate or interchange with standardized couplers:

Down-sizing of housing is an aspect that is ever more important for design of new appliances. You might consider a modification of standard or non-standard coupler systems that perfectly adapts your mounting requirements. The broad range of SCHURTER‘s standardized interconnection plugs and connectors is constantly being extended by new variations. When it comes to a special cord end terminations a high number of variations is available.

All SCHURTER standard and non-standard coupler systems meet the relevant requirements of product safety proved by multiple approval markings of international testing agencies.
