Its interrupting capacity reaches 20 kA Icu at 240 V AC (phase-to-phase, 50/60 Hz), 10 kA at 415 V AC, and 6 kA at 440 V AC, all conforming to EN/IEC 60947-2. The corresponding service breaking capacity (Ics) is 75 % of Icu at each voltage level — 15 kA, 7.5 kA, and 4.5 kA respectively — meaning the breaker can be reclosed after clearing a fault at those levels without immediate replacement. ## Standards, mounting, and environment Designed for fixed mounting on a 35 mm symmetrical DIN rail, the MGN60546 occupies 8 x 9 mm pitches (72 mm width) in the enclosure. The 73 mm depth and 81 mm height fit standard distribution board layouts. Rated IP20 (finger-safe terminals) per EN/IEC 60947-2, suitable for installation in a dry indoor panel. Pollution degree 3 per the same standard, so it tolerates conductive pollution typical of industrial control cabinets. The breaker carries a suitability-for-isolation marking (yes, per EN/IEC 60947-2) and a visible contact position indicator (ON/OFF indication) for safe isolation verification during maintenance. ## D-curve application context In a distribution board, this 4 A 4P unit protects a three-phase circuit with neutral, where the D-curve prevents nuisance tripping on the magnetizing inrush of a small transformer or the starting surge of a motor contactor coil. Rated for category A utilization (EN/IEC 60947-2), meaning it is not specifically intended for selectivity under short-circuit conditions with downstream breakers, though practical coordination is still achievable with careful selection.","metaTitle":"MGN60546 C60N MCB, 4P D-Curve 4A, 20kA, Multi9","metaDescription":"MGN60546 C60N miniature circuit breaker, 4-pole, D-curve, 4A rated. 20 kA breaking capacity at 240 V AC.
