Power Fuse

Power fuses protect transformers, substations and distribution lines at high voltage, built to interrupt very large fault currents without damaging the equipment around them. Substation crews lean on them when a feeder has faulted and the fuse has done its job, when a scheduled outage is the moment to replace units that have aged in service, or when a new distribution build needs coordination set between upstream and downstream protection.

 

As an authorized electrical distributor for multiple manufacturers, we stock power fuses from Littelfuse, Mersen and more across competing lines, in a full range of amperage and voltage ratings, so you can match what the existing holder and coordination study require, compare interrupting ratings across brands, and stock the sizes a substation actually turns over.
