Westinghouse HFD3020 Molded Case Circuit Breaker

The Westinghouse HFD3020 Molded Case Circuit Breaker is a 20 Amp, 3-pole device designed for industrial power distribution and motor control, rated for 600 VAC at 50/60 Hz. Its thermal-magnetic trip provides overload and short-circuit protection for 3-phase branch circuits, with bolt-on mounting in the HFD frame for durable MCC and control-panel installations. Commonly used in manufacturing equipment, automation panels, HVAC systems, conveyors, and processing gear, this breaker is well-suited to motor control centers and industrial cabinets where protection for connected equipment is required. Common replacements include Eaton HFD3020, Cutler-Hammer HFD3020, and Westinghouse HFD3020L.
