Breaking capacity is 30 kA Icu at 240 V AC phase-to-phase, 15 kA at 415 V AC, and 10 kA at 440 V AC. The Ics (service breaking capacity) is 50 % of Icu at those voltages — 15 kA at 240 V AC, 7.5 kA at 415 V AC, 5 kA at 440 V AC — and 40 kA at 125 V DC (100 %). That means after clearing a fault at the Ics level the breaker can be reclosed without immediate replacement, which matters for uptime in industrial distribution. Rated operational voltage is 440 V AC 50/60 Hz phase-to-phase, and the breaker is also rated for DC networks — 125 V DC with 25 kA Icu. The thermal-magnetic trip unit covers both overload and short-circuit protection; earth-leakage protection requires a separate block (Vigi or similar). The 3-pole body is 54 mm wide, 81 mm tall, 73 mm deep. Tunnel terminals accept 1.5...35 mm² rigid or flexible. IP20, pollution degree 3. Comb busbars and distribution blocks can feed top or bottom. The toggle gives local ON/OFF indication with a contact position indicator. Isolation-suitable per EN/IEC 60947-2 — use as a disconnecting means for the downstream circuit.","metaTitle":"MGN60643 C60H MCB, 3P C-Curve 32 A, 30 kA Breaking","metaDescription":"MGN60643 C60H miniature circuit-breaker, 3-pole, C-curve, 32 A rated current. 30 kA Icu at 240 V AC.
