Westinghouse F3100S Three-Phase Circuit Breaker

100 Amp, 600 VAC three-phase circuit breaker from Westinghouse AB DE-ION, catalog F3100S, designed for industrial power distribution and protection. It provides dependable overcurrent and short-circuit protection in switchgear, motor control centers (MCCs), and industrial distribution panels. This panel-mounted thermal-magnetic breaker blocks fault currents and isolates three-phase loads in heavy industrial environments, compatible with MCCs, switchboards, and distribution systems. The AB DE-ION F3100S is a 3-pole (3P) device rated at 100 A, 600 VAC, intended for replacement maintenance, electrical upgrades, retrofits, and restoration of legacy Westinghouse AB DE-ION equipment. Typical applications include manufacturing facilities, utility power systems, conveyors, process automation equipment, compressors, pumps, and other industrial electrical protection panels requiring robust overcurrent protection for safe operation. Ideal for system integrators and maintenance electricians handling industrial power distribution and protection tasks.
