Westinghouse 151D995 G08 Current Transformer Sensor

The Westinghouse 151D995G08 Current Transformer Sensor is a breaker-mounted current transformer designed to monitor load current in Westinghouse DS and DSII power circuit breakers equipped with Amptector or Digitrip electronic trip systems. Rated for 800 Amps, it measures current and provides input signals to the breaker's trip unit for overload, short-circuit, and ground fault protection functions. This CT sensor is commonly installed in low-voltage switchgear and power distribution systems within industrial and commercial facilities, supporting protection coordination for feeders, transformers, generators, and other critical electrical loads. Technical highlights include part number 151D995G08, current rating 800 A, CT-type current transformer, and compatibility with Amptector and Digitrip trip units on DS/DSII breakers, enabling accurate current sensing and protective relay input. Common replacements for this sensor are Eaton 151D995G08 Current Sensor and Cutler-Hammer 151D995G08 Amptector/Digitrip Sensor, reflecting its use in Westinghouse DS/DSII 800A current transformer sensor applications.
