The D-curve magnetic trip threshold of 12 x In (±20%) means it clears only on hard faults, not on normal magnetizing inrush. The 72 mm width (8 x 9 mm pitches) and 73 mm depth fit neatly into existing Multi9 or third-party distribution enclosures — no need to re-space the rail for a retrofit. Rated at 30 kA Icu at 240 V AC (phase-to-phase) and 15 kA at 415 V, this C60H sits above the standard C60 range in fault-clearing muscle. The service breaking capacity Ics is 50% of Icu at each voltage level — 15 kA at 240 V, 7.5 kA at 415 V — meaning after clearing a fault at that level the breaker remains functional enough to be reclosed. For a panel builder coordinating downstream branch circuits, that headroom simplifies selectivity with upstream devices rated 50 kA or higher. Thermal-magnetic trip unit, no external power required for the protection function. The toggle provides local ON/OFF indication and manual switching. Earth-leakage protection requires a separate Vigi block (not included) — plan for that module if the circuit needs residual current protection. The contact position indicator and isolation suitability (yes, per EN/IEC 60947-2) mean the breaker can serve as a visible disconnect in the panel, saving a separate switch.","metaTitle":"MGN25140 C60H MCB, 4P D-curve 3 A, Multi9","metaDescription":"MGN25140 C60H miniature circuit breaker, 4-pole D-curve, 3 A rated, 30 kA breaking capacity at 240 V.
