Schneider Electric M9F43310 3 Pole Circuit Breaker

Schneider Electric M9F43310 is a three‑pole miniature circuit breaker from the Multi9 C60BP family, rated at 10 A for protecting three‑phase circuits. It uses a thermal‑magnetic mechanism with a D‑curve trip characteristic, designed to respond quickly to short‑circuit faults while minimizing nuisance trips on inrush. This device is rated for up to 480Y/277 V AC and provides a 10 kA interrupting capacity under UL 489 and IEC/EN 60947‑2, making it suitable for branch‑circuit protection in commercial and light industrial panels and distribution boards. As part of Schneider Electric’s Multi9 portfolio, the M9F43310 supports three‑phase networks and is configured for standard panel installations that require a 3P, 10 A protection device with high fault-current capability, offering reliable protection across a range of loads and environments. Part of the Multi9 line, it adheres to a common 3P form factor and shared accessories across the family for streamlined panel design. This combination of current rating, voltage compatibility and high interrupting capacity helps protect downstream equipment and maintain safe, compliant electrical systems.
