Westinghouse Electric C0-2-L011AA1 Overcurrent Relay

The Westinghouse C0-2-L011AA1 Overcurrent Relay is a 1–12 A, 60 Hz current-sensing protective relay in the C02 series (Style 265C195A05) designed for industrial power protection and fault monitoring. This panel-mounted relay is used for overcurrent protection and fault monitoring in industrial power systems and is commonly installed in substations, switchgear assemblies, motor control centers, generator protection systems, and utility distribution networks requiring adjustable current protection. It supports generator, feeder, and transformer protection circuits and is suitable for replacement or retrofit projects to restore legacy Westinghouse protection schemes. Common replacements include ABB CO-2 Overcurrent Relay, GE Type CO Overcurrent Relay, and Westinghouse 265C195A03 Overcurrent Relay.
