Westinghouse FB3040V 3P Bolt On Circuit Breaker

Westinghouse FB3040V 3P Bolt-On Molded Case Circuit Breaker delivers secure three‑phase overcurrent protection for industrial power distribution, rated 40 A at 600 V. It is a 3‑pole bolt‑on device in the FB Frame and uses thermal‑magnetic protection with 50/60 Hz operation. It is commonly installed in motor control centers, switchboards, and industrial automation panels to protect medium‑amperage three‑phase circuits on 600‑V networks. Typical applications include MCCs, switchgear, and industrial control panels for motor control systems, conveyors, HVAC infrastructure, and automation equipment, providing branch circuit and equipment protection and serving as a reliable retrofit or replacement option for existing infrastructure.
