Littelfuse

Housed fuse strips for battery-powered vehicles. Current rating 35A - 500A, 80 VDC. 90° and straight fork type lugs. With window for visual inspection of melting element.

Littelfuse PSR Series High-Speed Square Body Fuses are specially designed for protection of power semiconductor devices such as diodes, triacs, IGBTs, SCRs, MOSFETs and other solid state devices that are typically designed into power conversion and power conditioning equipment. Variable frequency drives, inverters, UPS, rectifiers and soft-starters are examples of typical equipment designed with sensitive power semiconductor devices that cannot withstand any line surge or overcurrent conditions and require high-speed protection. Littelfuse POWR-SPEED® PSR Series products offer optimized circuit protection at the extremely fast speed required to protect modern day power conversion devices. Such products are commonly found in numerous applications including pulp and paper industries, cranes and heavy-lifting equipment, processing industries, wastewater treatment plants and various large factories and MRO facilities. Features/Benefits

Littelfuse FLSR series fuses have been the superior UL Class RK5 dual-element time-delay fuses, and are the most widely used class of fuses. FLSR series fuses provide excellent protection for all types of circuits especially those containing motors. However, users and specifiers should consider the significant benefits offered by Indicator fuses. Applications:

Main fuse for mounting with battery clamp on the battery pole. Voltage rating 58 VDC. Current rating 50A - 300A. With transparent cover for visual inspection of melting element.

The Littelfuse® POWR-PRO® JTD_ID Indicator Class J fuse provides visual blown fuse indication and maximum protection in a compact package. The compact Class J package was designed specifically for circuits where space is at a premium. The current limiting time delay JTD_ID offers a patented true dual-element design that is ideal for use in circuits with high inrush currents. Superior performance characteristics of JTD_ID Indicator fuses reduce nuisance fuse opening and the blown fuse indication reduces downtime and increases safety. Applications:

The P6SMB series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

The SMBJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

The 370 Series are TR5®, sub-miniature, fast-acting type, 250V rated fuses, designed in accordance to IEC 60127- 3.

10

Space-saving 600 volt, 30 amp molded-case fuse blocks with side barriers for isolation.

The 30KPA Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

The 1.5KE Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

The AEC-Q101 qualified TPSMC series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

The PolarP3™ HiPerFET™ product family is the latest addition to the benchmark high-performance Polar-Series product line for our product portfolio between 300V, 500V and 600V. Its high Figure of Merit (FOM) being the multiplication of Qg and in RDS(on) provide an excellent alternative to weaker super junction technologies. These PolarP3™ HiPerFETs demonstrate up to a 12 percent reduction in on-state resistance (Rdson), 14 percent reduction in gate charge (Qg) and as high as 20 percent increase in maximum power dissipation (Pd). Lower thermal resistances are also achieved due to reduced chip thicknesses, increasing total power density of the device.
