FLSR125 - Littelfuse 125 Amp 600 VAC 300 VDC Class RK5 Dual Element Time Delay Fuse

FLSR125

FLSR125 is a 125 amp dual element time delay fuse designed for superior circuit protection in industrial and general purpose applications.This Class RK5 fuse features a knife-blade construction and is rated for 600 VAC and 300 VDC operation. It provides excellent short-circuit and overload protection with a current-limiting, dual-element design. The fuse has a time-delay (Slo-Blo) characteristic to allow temporary overloads without blowing, making it ideal for motor circuits and other inductive loads. It has an interrupting rating of 200 kA at 600 VAC and 20 kA at 300 VDC, ensuring reliable interruption of high fault currents. The fuse is mounted using fuse blocks, clips, or holders compatible with the LFR60200 series.
