Westinghouse Electric LA3600WK Circuit Breaker

The Westinghouse LA3600WK is a three-pole molded-case circuit breaker designed for panel-mounted, non-automatic switching in commercial and industrial electrical distributions. Rated for 600 A at 600 V AC, it provides high-capacity overcurrent protection for 3‑phase power circuits and electrical equipment, with molded-case protection and dependable non-automatic switching. In practice, it's commonly installed in switchgear assemblies, motor control centers, industrial machinery, and commercial panels where reliable 600 A, three-phase switching and circuit isolation are required. The LA series device features fixed mounting and is intended for high‑capacity power distribution in commercial and industrial systems, including manufacturing facilities, industrial automation, HVAC equipment, and large-motor applications. Common replacements include Eaton LA3600NWS, Cutler-Hammer LA3600NWS, and Square D LA36600NS.
