Westinghouse 1000NBP14 Current Limiting Fuse for NB Frame Tri-Pac Breaker

Description:

The Westinghouse 1000NBP14 Current Limiting Fuse is a high-interrupting capacity TRI-PAC® De-Ion fuse designed for NB Frame circuit breakers used in industrial and commercial power distribution systems. Commonly installed in Westinghouse NB Frame TRI-PAC breaker assemblies, switchgear, motor control centers, and heavy industrial electrical distribution equipment requiring fast fault-current interruption and current-limiting protection. Maintenance electricians, facility engineers, and industrial power technicians use this fuse for replacement, retrofit, or protection system maintenance.

Applications:

The Westinghouse 1000NBP14 current limiting fuse is commonly used in industrial electrical systems to protect NB Frame TRI-PAC molded case circuit breakers, feeders, transformers, and large motor circuits from short-circuit and overload conditions. It is installed in manufacturing facilities, process plants, utility distribution systems, and industrial machinery where dependable high-speed fault interruption and reduced let-through energy are required. TRI-PAC current-limiting technology helps minimize thermal and mechanical damage during high fault-current events.
