Square D M9F22306 Molded Case Circuit Breaker

The Square D Multi9 M9F22306 is a 3‑pole molded‑case circuit breaker (MCB) engineered for distribution and protection on 480Y/277 VAC systems, delivering a 6 A rated current with a C‑curve trip and a 10 kA breaking capacity (UL 1077) as well as IEC/EN 60947‑2 compliance. It is part of Schneider Electric’s Square D Multi9 family and is identified by the M9F22306 designation, a DIN‑rail mounted 3P MCB designed for compact three‑phase protection in control panels and small industrial installations. This device is designed for quick DIN rail installation and works with other Multi9 components within Schneider Electric’s catalog, making it a practical choice for modern modular panel boards where reliable overcurrent protection is required. Engineered for 480V nominal applications, the M9F22306 combines a compact 6‑amp frame with proven protection characteristics suitable for lighting, small motors, and auxiliary power circuits in commercial or light industrial environments. Its 10 kA breaking capacity under UL 1077 and IEC 60947‑2 ensures robust fault interruption for safe operation, while the 3P configuration provides protection across all three phases of a circuit in one compact unit.
