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.
Available in DIN4 3653 blade style termination with visual
blown fuse indication standard on all fuses and optional
micro-switch for external indication.

Environmental RoHS Compliant, REACH
Operating Temperature -55 °C to +125 °C
