Westinghouse Electric FB3070PL Circuit Breaker

The Westinghouse Tri-Pac FB3070PL is a 70 Amp, 3-pole molded case circuit breaker (Part Number FB3070PL) rated for 600 VAC and designed for high-capacity, three-phase protection in industrial electrical distribution. This Type FB device uses thermal-magnetic technology to deliver reliable overcurrent and short-circuit protection for branch circuits and connected equipment, making it a core component in motor control centers, switchboards, and large automation panels. It is intended for panel or switchboard mounting and supports 3-phase systems operating at 50/60 Hz, with the ability to protect conveyors, HVAC infrastructure, automation machinery, and other manufacturing equipment that rely on robust power distribution. Common replacements include Eaton FB3070, Siemens HFB3070, and Square D FA3470, which can be used for retrofit upgrades or spare inventory in existing installations. Note: the housing/case is chipped, which may be relevant for installation or replacement considerations in refurbished contexts.
