Westinghouse 1875360A

Description:

The Westinghouse 1875360A is a Type CO-8 electromechanical overcurrent relay designed to provide inverse-time overcurrent protection for power distribution systems. The relay monitors current through connected current transformers (CTs) and initiates a trip signal when current exceeds preset pickup values. It is commonly used for feeder, transformer, motor, and distribution circuit protection in substations, switchgear, and industrial electrical systems.

Applications:

The Westinghouse 1875360A overcurrent relay is commonly installed in utility substations, industrial plants, power generation facilities, switchgear assemblies, and electrical distribution networks. It provides protective relaying for feeders, transformers, motors, and generators by detecting overload and fault conditions and initiating circuit breaker tripping when required.
