Westinghouse FB3015 Molded Case Circuit Breaker

The Westinghouse FB3015 is a three‑pole molded‑case circuit breaker (15 A) designed to provide overcurrent and short‑circuit protection in industrial and commercial power distribution systems. Its panel‑mount design supports up to 600 VAC and delivers a 14 kA interrupting rating at 480 VAC, making it suitable for protecting branch circuits and motor loads in switchboards, panelboards, motor control centers, and industrial machinery. Common applications include manufacturing facilities, commercial buildings, HVAC systems, and other industrial power distribution equipment requiring dependable protection for branch circuits and motor loads. For field replacements and retrofit projects, common alternatives include Siemens ED63B015, as well as Eaton FB3015 and Eaton BAB3015 circuit breakers.
