The Westinghouse HKB3175T Circuit Breaker is a 3-pole, 175 Amp thermal-magnetic device rated for 600 V AC, built for industrial electrical distribution. It is commonly installed in switchgear assemblies, motor control centers, and commercial electrical panels to deliver reliable overcurrent and short-circuit protection for three-phase power circuits. Mounted in panels or switchgear, this breaker is used in manufacturing facilities, commercial infrastructure, and other power distribution systems where dependable fault interruption is required; maintenance teams use it for aging-equipment replacement, system upgrades, and preventative maintenance of power infrastructure.
