The Westinghouse FDC3040 is a three-pole, 40A molded case circuit breaker (600V-AC) from the FDC Frame series, designed for industrial electrical distribution and branch-circuit protection. Its thermal-magnetic protection provides overcurrent and short-circuit protection for 3-phase systems operating at 50/60 Hz. Mounted in panels or switchboards, it is commonly installed in motor control centers, switchgear, and industrial control panels for motor control applications, conveyors, HVAC infrastructure, automation equipment, and other medium-amperage loads.
