Littelfuse high-speed (semiconductor) fuses protect critical power electronics from over-currents that may cause damage to electronic equipment. The company’s high-speed fuses are reliable, very fast-acting products that can reduce the amount of short circuit current and improve the life of power semiconductor devices.
Its POWR-Speed fuses feature an innovative bridge design, arc-quenching material and a robust element to provide fast, extreme current limitation exactly where it’s needed.
The square body PSR fuses in this family are specifically 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 over-current conditions and require high-speed protection.
POWR-Speed PSR series products offer optimised 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.
The new round-body QS series fuses have reduced the energy let-through by up to 70% over previous generation high-speed semiconductor fuses. They have high-performance silver fuse elements that combine with a hardened silica filler to provide enhanced system protection.
