Industrial FB3070 Molded Case Circuit Breaker

The Westinghouse FB3070 Molded Case Circuit Breaker is a 70 Amp, 3-pole device in the FB Frame series, designed for three-phase overcurrent protection in industrial power distribution and motor control applications. This molded case breaker provides thermal-magnetic protection for branch circuits and equipment and is intended for panel or switchboard mounting. It is rated for 50/60 Hz operation and supports three-phase systems, making it suitable for high-amperage protection in motor control centers, switchboards, industrial automation panels, and manufacturing equipment. Typical installations include MCCs, switchgear, and industrial control panels where dependable branch circuit protection is required for higher-amperage three-phase power systems. In demanding industrial environments, the FB3070 protects connected equipment such as motors, conveyors, HVAC infrastructure, and industrial processing machinery from overcurrent and short-circuit events. Maintenance teams, OEMs, and electrical integrators use this breaker for replacement, retrofit upgrades, and ongoing maintenance of existing industrial electrical infrastructure.
