Westinghouse FD3015L Molded Case Circuit Breaker

The Westinghouse FD3015L Molded Case Circuit Breaker is a three-pole, 15-amp thermal-magnetic device in the FD frame designed for dependable overcurrent protection in 600-volt electrical systems. It serves as branch-circuit and equipment protection in motor control centers, switchboards, and industrial automation panels, including conveyors, HVAC infrastructure, and manufacturing equipment that rely on three-phase power. With an interrupt rating of 35 kA at 480 VAC and a 50/60 Hz frequency rating, it accommodates common industrial power networks while supporting a feed-thru configuration for straightforward wiring in MCCs and industrial control panels. The FD3015L is intended for power distribution and motor control systems in industrial and commercial settings, delivering reliable protection against overcurrent and short circuits. For compatibility and sourcing, common replacements include Eaton FD3015L, Siemens HFD3015, and Square D FA3415.
