Westinghouse FB3030L Molded Case Circuit Breaker

The Westinghouse FB3030L (Part Number FB3030L) is a 30 Amp, 3-pole molded case circuit breaker built on the FB frame for reliable three-phase overcurrent protection in industrial electrical distribution up to 600 VAC. Its thermal-magnetic design provides overload and short-circuit protection and it is intended for panel or switchboard mounting in motor control centers, switchgear, and industrial control panels. Rated for 50/60 Hz operation, the FB3030L is used for branch circuit and equipment protection in medium-amperage three-phase systems such as conveyors, HVAC infrastructure, automation machinery, and other power distribution panels operating on 600 VAC.
