Schneider Electric FAB360451021 Circuit Breaker

The Schneider Electric FA360451021 is a 3‑pole molded‑case circuit breaker (MCCB) rated for 45 A at up to 600 V, suitable for protecting three‑phase feeders in 600 V systems. Part of the Square D FA family, it uses I‑Line line‑side termination with load‑side lug connections for plug‑in installation in compatible panels. It provides a thermal‑magnetic trip mechanism and has a listed interrupt rating of 25 kA at 240 VAC, 18 kA at 480 VAC, and 14 kA at 600 VAC, aligning with typical protection needs of three‑phase distribution circuits. This device is designed for 3‑pole operation and is intended for use in FA panel lineups that support 3P 600 V MCCBs.
