Westinghouse Electric Corporation LAB3250 Circuit Breaker

The Westinghouse LAB3250 molded case circuit breaker is a 3-pole, 250 A device rated for 600 V AC, delivering thermal-magnetic overcurrent and short-circuit protection for high-capacity three-phase power circuits. Designed for panel-mounted installations, it includes line and load lugs and is commonly installed in switchgear, panelboards, motor control centers, and industrial electrical panels to protect commercial and industrial distribution systems. Applications span manufacturing facilities, commercial buildings, HVAC systems, and industrial automation equipment where reliable fault interruption and equipment protection are critical. Common replacements include Eaton LAB3250, Cutler-Hammer LAB3250, and Square D LA36250.
