Schneider Electric FAL340451212 Circuit Breaker

Schneider Electric's Square D FAL340451212 is a 45A, three‑pole molded‑case circuit breaker in the FA (F‑frame) family. The FAL340451212 designation identifies a 3‑pole device within Schneider Electric’s FA/FAL line, built to protect three‑phase distribution circuits by interrupting current on overload or short‑circuit conditions. As part of the FA (F‑frame) molded‑case breakers, this unit is designed for use in compatible Square D panels and enclosures, offering consistent mounting, operability, and interchangeability with other breakers in the same family. With a 45‑amp rating, it provides targeted protection for branch circuits serving three‑phase equipment in commercial, industrial, and institutional settings. The FAL340451212 model is typically chosen when a higher level of protection is required for a three‑phase distribution path, and its three‑pole construction ensures simultaneous disconnection across all phases for enhanced safety and fault clearance. When paired with the appropriate accessories and buses from Schneider Electric, it integrates into standard Square D electrical distribution systems, enabling clear labeling, coordinated protection, and reliable service continuity.
