Schneider Electric M9F22170 Miniature Circuit Breaker

Schneider Electric M9F22170 is a 1-pole Miniature Circuit Breaker (MCB) in the Multi9 C60SP family, rated at 0.5 A with a C-curve trip characteristic and a 10 kA interrupting capacity under UL 1077 and IEC/EN 60947-2. Rated for 277 V AC operation, it protects single-phase circuits in commercial and light-industrial power distributions. This compact device is intended for low-current loads such as lighting branches and general-purpose circuits, delivering predictable tripping behavior to minimize fault impact. As part of Schneider Electric's Multi9 lineup, the M9F22170 integrates with standard C60SP enclosures and provides reliable protection for small branch circuits in modern electrical installations.
