Westinghouse FDB3020L Circuit Breaker

Westinghouse FDB3020L is a 20 A, 600 VAC three-pole molded case circuit breaker in the FDB frame, configured in an L configuration for panel or switchboard mounting. This thermal-magnetic device delivers overcurrent and short-circuit protection for branch circuits and equipment within industrial power distribution and motor control systems. It is commonly installed in motor control centers, switchboards, and industrial automation panels where low-amperage three-phase protection is required, and it is suitable for manufacturing equipment operating on 600 VAC networks. The unit supports 50/60 Hz operation and is designed for MCCs, HVAC infrastructure, conveyor controls, automation machinery, and other industrial processing systems. Typical installations include MCCs, switchgear, and industrial control panels, aligning with the Westinghouse brand and part number FDB3020L. Common replacements include Eaton FDB3020L, Siemens HFD3020, and Square D FA3420.
