Schneider Electric FY-14015-B Circuit Breaker

Schneider Electric's Square D FY14015B is a 1‑pole molded‑case circuit breaker in the FY family, rated for 277 VAC at 15 A and designed for I‑Line bus configurations in industrial distribution panels. This thermal‑magnetic device provides overcurrent protection with an 18 kA interrupt rating in a 480Y/277 VAC system, and the FY14015B reference was discontinued on July 12, 2021; Schneider Electric lists the PowerPacT B, 15 A, 1‑pole, 480Y/277 VAC, 18 kA, I‑Line, thermal magnetic as its replacement, with a cross‑reference to BDA140153 for compatibility. This part belongs to Square D’s legacy lineup and is typically used in legacy installations where the FY frame supported I‑Line mounting and standard branch protection in 277 VAC industrial applications.
