Westinghouse 1875360A Electromechanical Overcurrent Relay

The Westinghouse 1875360A CO-8 electromechanical overcurrent relay delivers inverse-time protection for power distribution by sensing current through connected current transformers and tripping a circuit breaker when pickup values are exceeded. Its electromechanical induction disc mechanism provides adjustable time-current characteristics for selective coordination and fault protection of feeders, transformers, motors, and generators. This panel-mounted protective relay assembly is designed for utility and industrial power systems, with CT-operated input and suitability for substations, switchgear, and industrial electrical installations. Applications include protection of feeders, transformers, motors, and generators against overload and faults in industrial, commercial, and utility environments.
