Schneider Electric M9F23406 4 Pole Circuit Breaker

Schneider Electric M9F23406 is a four-pole miniature circuit breaker in the Multi9 C60SP family, designed for three‑phase distribution with a shared neutral and DIN-rail mounting in standard enclosures. This 6 A device uses a Type D (delayed) trip curve to tolerate inrush and mixed loads common in commercial and light industrial panels, while delivering thermal-magnetic overcurrent protection. It is rated for line voltages up to 240/415/440 V AC and provides a breaking capacity of 10 kA under UL 1077 and IEC/EN 60947‑2, ensuring quick interruption of fault currents. The M9F23406’s four‑pole configuration protects all three phases plus the neutral, which helps prevent nuisance trips and provides reliable protection for equipment such as motors, pumps, conveyors, and control circuits in panel boards. As part of Schneider Electric’s Multi9 line, this MCB is designed for easy integration into existing assemblies, with conforming mechanical dimensions for quick snap‑in mounting on a standard DIN rail.
