WESTINGHOUSE 151D933G02 - FUSE

Description:

The Westinghouse 151D933G02 is a medium-voltage current-limiting power fuse designed to provide fast and reliable protection against overloads and short-circuit faults in electrical distribution systems. Classified as a CLS-12 type fuse, it is rated for 5.08 kV and 230 Amps and is commonly used in switchgear, transformer protection circuits, feeder applications, and utility power distribution equipment. The fuse is engineered to rapidly interrupt fault currents, helping minimize equipment damage and improve overall system protection.

Applications:

The Westinghouse 151D933G02 fuse is commonly installed in substations, industrial facilities, utility distribution networks, manufacturing plants, and commercial power systems. It is used to protect transformers, feeders, switchgear, and other medium-voltage equipment from excessive fault currents and overload conditions. Its current-limiting design helps reduce thermal and mechanical stresses on downstream equipment during fault events.
