The C-curve means the magnetic trip operates between 5 and 10 times In — here specified at 8.5 x In ±20 % — so it's sized for moderate inrush loads like small motor starters or lighting banks where the start-up surge won't nuisance-trip a B-curve but doesn't need the higher threshold of a D-curve for heavy transformer or welding loads. Breaking capacity is the headline number that decides whether this breaker holds in a fault scenario: 30 kA Icu at 240 V AC phase-to-phase, 15 kA at 415 V, 10 kA at 440 V, and 50 kA at 250 V DC — all per EN/IEC 60947-2. The rated service breaking capacity Ics is 50 % of Icu at those AC voltages (15 kA / 7.5 kA / 5 kA) and 100 % at 250 V DC (50 kA), telling you it can clear multiple faults at the lower level and still be reclosed. Rated operational voltage covers 240 V, 415 V, and 440 V AC 50/60 Hz phase-to-phase, plus 250 V DC — so it's a dual-rated unit for AC distribution panels and DC circuits like battery banks or solar combiner boxes, as long as the voltage and polarity are within those limits. The 4 protected poles mean all four poles have overcurrent protection; the fourth pole is switched but not necessarily a fully rated neutral in all applications — check the specific wiring diagram for your panel. IP20 finger-safe protection on the front face — fine for enclosed panels where the breaker is behind a locked door or cover. The comb busbar and distribution block compatibility (top or bottom) lets you feed multiple breakers from a common bus without daisy-chaining wire tails. Dimensions are 81 mm high, 72 mm wide, 73 mm deep. The 72 mm width occupies four standard DIN-rail module positions. Certified to EN/IEC 60947-2. Suitability-for-isolation marking is yes per that standard. ## Durability and environmental range Electrical durability is 10,000 cycles under load per EN/IEC 60947-2; mechanical durability is 20,000 cycles. For a distribution breaker that sees infrequent switching (maybe a few times a year for maintenance), that's effectively a lifetime rating. If it's used as a daily disconnect in a process line, the electrical cycles still give you decades of service before the contacts wear out. The 25 A rating is at 50 °C.","metaTitle":"MGN60655 C60H MCB, 4P C-Curve 25 A, 30 kA Breaking Capacity","metaDescription":"MGN60655 Schneider C60H miniature circuit-breaker, 4-pole, C-curve, 25 A rated current. 30 kA Icu at 240 V AC per EN/IEC 60947-2.
