Westinghouse FD3030 Molded Case Circuit Breaker

The Westinghouse FD3030 Molded Case Circuit Breaker is a 30 Amp, 3‑pole device in the FD frame designed for 600 VAC distribution in industrial environments. Built as a molded case circuit breaker with thermal‑magnetic protection, it provides overcurrent and short‑circuit protection for medium‑amperage three‑phase systems in motor control centers, switchboards, industrial automation panels, and manufacturing equipment requiring three‑phase overcurrent protection. It mounts in panels or switchboards and is specified for 50/60 Hz networks, delivering a 25 kA interrupt rating to clear faults on branch circuits and connected equipment. The FD3030 is commonly used in industrial and commercial electrical systems where branch circuit protection is required for medium‑amperage three‑phase equipment operating at 600 VAC. End users such as maintenance teams, OEMs, and electrical integrators typically choose it for replacements, retrofit upgrades, and ongoing maintenance of existing industrial infrastructure. Common replacements include Eaton FD3030, Siemens HFD3030, and Square D FA3430, underscoring its role in three‑phase protection across industrial facilities.
