Westinghouse FDB3060L Molded Case Circuit Breaker

The Westinghouse Circuit Breaker FDB3060L is a 3-pole molded case breaker rated for 60 A at 600 V, designed for industrial electrical distribution and branch circuit protection. Built on the FDB Frame with an L configuration, this thermal-magnetic device provides reliable overcurrent and short-circuit protection for three-phase power networks. It is a panel- or switchboard-mounted unit intended for motor control centers, switchgear, industrial automation panels, and manufacturing equipment that require medium-amperage protection. The breaker supports 50/60 Hz operation and is suitable for power distribution and motor control systems across industrial and commercial installations. Its 3-pole, 3-phase configuration and 600 V rating make it compatible with typical MCCs, switchgear deployments, and industrial control panels operating on medium-voltage distribution. Common replacements when upgrading or retrofitting include Eaton FDB3060L, Siemens HFD3060, and Square D FA3460, reflecting its role in cross-brand compatibility within standard industrial protection schemes.
