Westinghouse FD3030 Molded Case Circuit Breaker

The Westinghouse FD3030 Molded Case Circuit Breaker is a 3‑pole, 30 A device rated for 600 V with a 25 kA interrupt rating, part of the FD Frame family for dependable three‑phase overcurrent protection in industrial power distribution. It uses thermal‑magnetic protection to interrupt excess current and short circuits, making it suitable for branch circuits and equipment in motor control centers, switchboards, and industrial automation panels. With a panel or switchboard mounting style and a 50/60 Hz frequency rating, the FD3030 is commonly installed in MCCs, switchgear, and industrial control panels where medium‑amperage three‑phase loads require reliable protection on 600 V systems. Typical applications include motor control systems, conveyors, HVAC infrastructure, and other manufacturing equipment within industrial facilities. Common replacements include Eaton FD3030, Siemens HFD3030, and Square D FA3430.
