Schneider Electric MGN60874 is a C60N miniature circuit breaker from the Multi9 range — a 1-pole, 63 A thermal-magnetic MCB with a C-curve trip characteristic (magnetic trip at 8.5 x In ±20 %). It breaks 10 kA Icu at 240 V AC phase-to-neutral per EN/IEC 60947-2, with an Ics of 7.5 kA (75 %) at the same voltage. The 63 A rating at 50 °C gives you headroom for continuous loads without derating in a warm enclosure.
Occupies one module position in a standard distribution board — no extra gap needed for heat dissipation at 63 A. Tunnel terminals accept 1.5 to 35 mm² rigid or flexible (with/without ferrule); tighten to 3.5 N·m. Strip 14 mm of insulation. The IP20 finger-safe front is standard for enclosed panels.
