The Westinghouse JB2250K is a molded case circuit breaker from the AB DE-ION family, designed for instantaneous magnetic-only protection in industrial power systems. This 2-pole, single-phase unit is rated for 250A at 600VAC, with an interrupting capacity of 22kA at 480VAC, and features a bolt-on connection for secure panel mounting. The breaker weighs 17 lb and is constructed for robust performance in high-fault environments, utilizing a magnetic-only trip mechanism for instantaneous response to short circuits. It complies with industry standards for molded case breakers, ensuring reliable overcurrent protection in distribution panels and switchboards. Typical applications include motor control centers, feeder circuits, and industrial machinery requiring precise magnetic trip coordination.
