Breaking capacity reaches 30 kA Icu at 240 V AC phase-to-phase, 15 kA at 415 V, and 10 kA at 440 V, all per EN/IEC 60947-2. The 4-pole body occupies 8 module pitches of 9 mm each, so plan for 72 mm of panel width. Strip 14 mm of insulation. ## Environmental and isolation IP20 finger-safe terminals. Suitability for isolation is confirmed per EN/IEC 60947-2, with a visible contact position indicator. Listed as current production. The C60H platform is a mature, widely stocked line in the Multi9 family.","metaTitle":"MGN25143 C60H MCB, 4P D-curve 10 A, 30 kA","metaDescription":"MGN25143 C60H miniature circuit breaker, 4-pole D-curve 10 A, 30 kA breaking capacity at 240 V.
