Description:
The Westinghouse FB3045MRL is a 5 A, 3‑pole molded case circuit breaker built for 600 VAC industrial distribution, delivering reliable overcurrent and short‑circuit protection in a compact package. It uses a thermal‑magnetic mechanism within the FB frame and is suitable for panel or switchboard mounting in MCCs, switchgear, and industrial control panels. Ideal for automation systems, motor control centers, conveyor controls, HVAC infrastructure, and other equipment on 50/60 Hz 600 VAC networks, this breaker is commonly used where low‑amperage three‑phase protection is required. Common replacements include Eaton FB3005, Siemens HFB3005, and Square D FA34005.
