Westinghouse 140D325G03 Fuse Current Limiting 1200 Amp 600 VAC 60 Hz Type NCI

Description:

The Westinghouse 140D325G03 is a Type NCI/NCL current-limiting fuse designed for high-capacity industrial and commercial power distribution systems. This low-voltage fuse provides fast-acting overcurrent and short-circuit protection while limiting fault current energy to help protect downstream equipment from damage. Rated at 1200 Amps and 600 VAC, it is commonly installed in switchboards, switchgear, motor control centers, and large power distribution systems where high interrupting capacity and current-limiting performance are required.

Applications:

The Westinghouse 140D325G03 current-limiting fuse is commonly used in industrial plants, commercial facilities, utility systems, manufacturing operations, and power distribution networks to protect feeders, transformers, motor circuits, and electrical distribution equipment from overloads and fault currents. Current-limiting fuses help reduce thermal and mechanical stress on protected equipment by rapidly interrupting high fault currents.
