The C60N delivers 20 kA Icu at 240 V AC phase-to-phase, 10 kA at 415 V, and 6 kA at 440 V — all per EN/IEC 60947-2. The corresponding Ics (service breaking capacity) is 75 % of Icu at each voltage level: 15 kA at 240 V, 7.5 kA at 415 V, and 4.5 kA at 440 V. That Ics margin means the breaker can be reclosed after clearing a fault at those levels without immediate replacement, which matters for selectivity coordination in a distribution board. ## Trip curve and application The D-curve magnetic trip is set at 12 x In ±20 %, so the breaker holds through motor inrush and transformer energization without nuisance tripping. Thermal-magnetic trip technology covers both overload and short-circuit protection. Rated operational voltage is 440 V AC phase-to-phase, 240 V phase-to-neutral. The 4-pole unit occupies 8 x 9 mm pitches (72 mm wide). Pollution degree 3 per EN/IEC 60947-2, IP20 finger-safe terminals.","metaTitle":"MGN60550 C60N MCB, 20A 4P D-Curve, 20kA at 240V","metaDescription":"MGN60550 C60N miniature circuit breaker, 20 A rated, 4-pole, D-curve, 20 kA breaking capacity at 240 V AC.
