Westinghouse CTK250 Neutral Current Sensor Module

The Westinghouse CTK250 Neutral Current Sensor Module is an industrial current sensing device designed for neutral current detection and protective relay input in power distribution and ground fault monitoring systems. Rated for 250 A with a 250:6 A current ratio, it supports panel or switchgear installations and integrates with protective relays and ground fault monitoring equipment. The device performs AC current transformation and monitoring and is built in an industrial-duty sensor housing for continuous operation in demanding environments. Commonly deployed in switchgear assemblies, motor control centers, industrial substations, and broader industrial power distribution networks for neutral current measurement, metering, and relay input.
