The MGN60651 is a 6 A C-curve 4-pole miniature circuit breaker from the Schneider C60H series (Multi9 range), rated for distribution duty under EN/IEC 60947-2. The 30 kA Icu at 240 V AC phase-to-phase means it safely interrupts faults up to 30 kA at that voltage; at 415 V AC the rating drops to 15 kA, and at 440 V AC to 10 kA. For DC circuits, the 50 kA Icu at 250 V DC is the figure to use. The 4-pole configuration protects all four conductors in a three-phase-plus-neutral system; the fourth pole is switched, not just neutral disconnection.
The 72 mm width occupies 8 x 9 mm pitches — standard for a 4P MCB in the Multi9 family. Strip length is 14 mm. IP20 finger-safe terminals are fine for enclosed panels; no washdown rating. Comb busbar compatible top or bottom.
