SCHURTER is initially offering the SHT 6.3x32 in ten rated currents from 1 to 8 A. The fuse stands out due to its high breaking capacity of 1500 A at a voltage rating of 500 VAC. Besides a wide range of applications in the energy and industrial sectors, the SHT 6.3x32 is especially well suited for the protection of 3-phase systems.

SCHURTER offers the SHT 6.3x32 as a fuse link or a version with pigtails. Fuse links can be used in clips and fuse holders, which allows easy replacement of fuses without de-soldering. SCHURTER offers a broad range of such clips and fuse holders suited for use with the SHT 6.3x32. The pigtail version allows direct assembly on printed circuit boards by means of through-hole technology and soldering.

As a fuse that conforms to RoHS, the SHT 6.3x32 can be put to use in lead-free systems. Compatibility with the most important competitive products allows SCHURTER to offer the SHT 6.3x32 as a form, fit and function substitute product. The SHT 6.3x32 fuse is cURus approved.

The ASO solar fuse has been specifically designed for the protection of photovoltaic systems. This fuse can safely protect PV modules and conductors from reverse overcurrent conditions.

As PV systems have grown in size, so have the corresponding voltage requirements. This increase in system voltage has typically been intended to minimise power loss associated with long conductor runs. Standard circuit protection devices are not designed to completely protect photovoltaic panels. However, the ASO solar fuse is UL listed to safely interrupt faulted circuits up to this demanding volt-age level.

SCHURTER offers 13 different ampere ratings to match specific requirements of various applications, such as inverters and battery charge controllers or to be used as inline or string fuse. A PCB version and bolted contacts are also available on request. Moreover, SCHURTER provides the appropriate touch-safe fuse holder (FSO) and fuse clip (231660).

The product includes UL approval and is RoHS compliant. VDE approval is currently in process.

SCHURTER has extended the current rating of the successful 250 VAC, IEC time-lag sub miniature SMD fuse UMZ 250. This SMD fuse with clip is now available in 18 different current ratings from 80 mA to 4 A.

The UMZ 250 offers time-lag T characteristic according to IEC 60127-4 and is an Universal Modular Fuse (UMF) with rated current values from 80 mA up to 4 A. The approved voltages are 250 VAC and 125 VDC according to IEC and 277 VAC and 250 VDC according to UL. The device provides a high breaking capacity of up to 200 A at rated voltage.

The ultra-small profile allows fast cycling when used with pick & place electronic assemblies. Beyond the benefit of space-saving designs, one single fuse can be used for primary and secondary over-current protection. The target applications are over-current protection for power supplies, storage systems, wireless base station and many other electronic systems, all with the same SMD fuse.

The UMZ 250 is RoHS compliant and carries all main approvals. It is offered in plastic bags and standard reels.

SCHURTER introduces the new solar fuse ASO and fuseholder FSO with quick-acting characteristic to protect photovoltaic and similar DC-applications. The new product extend the strategic segment “renewable energy�? with a 1000 VDC fuse with a current range from 1 A to 30 A and a touch safe fuseholder FSO. As PV systems have grown in size, so have their circuit protection requirements such as voltage rating. This high performance DC fuse is in a compact 10.3x38 mm package.

The ASO fuse protects PV modules, conductors and similar DC-applications from the potentially devastating effects of a low short circuit current in systems upwards of 1000 VDC.

The wire bonding makes the fuse stable and reliable with an operating temperature range of -40°C to 85°C. The ASO fuse is especially designed for protecting DC low short circuit current and overvoltage conditions like solar panels (strings), inverters, battery charges and combiner boxes. The touch safe fuseholder FSO is designed for grid-tie or off-grid array combiners and standard DIN rail mount.

The products includes cURus agency approval, are RoHs compliant and halogen-free.

Schurter introduces the new USFF 1206 fuses with super-quick-acting characteristic for low current applications. The new product extends the current range of the successful USF 1206 for lower ratings ranging from 160 to 250 mA. The wire bonded fuse offers extremely low impedance values compared to competitive products, providing exceptional performance in dense circuits.

Unlike competing fuses, the USFF 1206 200 mA version offers a voltage drop value at rated current of 87 mV, which is about 3 times less than competive products. The wire bonding makes the fuse stable and reliable with an operating temperature range of -55 °C to 90 °C. It is especially designed for protecting DC over-current conditions where heat dissipation is critical, including computer peripherals and communication equipment. The product includes cURus agency approval and is RoHS compliant and halogen-free.

The UMZ 250 offers time-lag characteristic according to IEC 60127-4 and is a Universal Modular Fuse (UMF) with rated current values from 315 mA to 4 A. The product provides a high breaking capacity of up to 200 A at 250 VAC. The clip option allows a customer fuse replacement with the benefit that only the UMT 250 fits. This has the advantage that e.g. the technical specification in contrast to a 5x20 mm solution does not vary and spare fuses could be sold through the equipment manufacturer. With this setup, the manufacturer receives important information about equipment failures in the field. Gold cap are required, in order that the clip and the fuse are not soldered together in the reflow soldering process. As replacement, the standard UMT 250 can be used instead.
