Description

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.
