The Westinghouse FB3070L Molded Case Circuit Breaker is a 70 Amp, 3-pole device built on the FB Frame for three-phase overcurrent protection. Designed with a thermal-magnetic mechanism, it provides overcurrent and short-circuit protection and is panel or switchboard mounted. It is intended for industrial electrical distribution and is commonly used in motor control centers, switchboards, automation panels, conveyors, HVAC infrastructure, and other manufacturing equipment requiring reliable high-amperage protection at 50/60 Hz. Typical installations include MCCs, switchgear, and industrial control panels.
