Westinghouse GD 22K Molded Case Circuit Breaker

The Westinghouse GD 22K is a 3-pole, 480 V molded case circuit breaker designed for reliable three‑phase overcurrent protection in industrial electrical distribution. With a 22 kA interrupt rating and thermal-magnetic protection, it mounts in panels or switchboards for branch circuit and equipment protection on 50/60 Hz power networks. Common applications include motor control centers, switchgear, industrial control panels, HVAC infrastructure, conveyors, automation systems, and other manufacturing equipment operating on 480 V. As part of the GD series, the GD 22K serves as a replacement or retrofit option for compatible GD-series breakers in maintenance and upgrade projects.
