Westinghouse 6379D26H20 Current Limiting Fuse

Westinghouse 6379D26H20 Double-Barrel Current-Limiting Fuse is a 390 A, 5.5 kV medium-voltage protection device (GCLS25 style) engineered for rapid fault interruption. It delivers short-circuit and overload protection for medium-voltage circuits in switchgear, transformers, and motor starters. Designed for 50/60 Hz operation, it mounts in fuse holders or directly in switchgear and is suitable for utility substations, industrial processing facilities, power generation, mining, and heavy manufacturing environments on 5.5 kV networks. This current-limiting, double-barrel fuse provides reliable protection in medium-voltage power distribution.
