Westinghouse MC3800F Molded Case Circuit Breaker

The Westinghouse MC3800F is a 3-pole molded‑case circuit breaker engineered for high‑amperage, three‑phase protection in industrial and commercial power distribution. It is rated for 800 A and 600 V AC, with a 30 kA interrupt rating at 480 V AC, and uses electronic trip protection with interchangeable rating plugs. The bolt‑on mounting and bolt‑on/lug connection support easy installation in switchgear, motor control centers, and other large power distribution assemblies, and it belongs to the Westinghouse SELTRONIC MC frame series. Common applications include manufacturing facilities, industrial automation systems, mining operations, HVAC infrastructure, data centers, and heavy‑duty power distribution where reliable overcurrent and short‑circuit protection is critical.
