Westinghouse Electric Corporation LAB3400W Circuit Breaker

Westinghouse LAB3400W is a three-pole, 200 A molded case circuit breaker from the LAB series, designed for bolt-on mounting in commercial and industrial power-distribution systems to provide thermal-magnetic overcurrent and short-circuit protection for high-capacity three-phase circuits up to 600 V AC. This 600 V AC, 200 A unit (part number LAB3400W) is built for bolt-on panel-mount installation and is commonly used in switchgear, panelboards, motor control centers, and other distribution equipment requiring molded-case protection. It serves as a reliable replacement or upgrade for aging protection devices in manufacturing facilities, commercial buildings, HVAC systems, and industrial automation where dependable fault interruption and branch-circuit protection are critical for safe, continuous operation. Its thermal-magnetic trip and molded-case construction help ensure coordination with upstream protection and reliable operation in demanding environments.
