Breaking capacity is 3 kA under both EN 60898 and IEC 60947-2, so it's sized for residential or light commercial sub-distribution, not high-fault industrial mains. Installation depth is 55 mm and it occupies 2 width units (36 mm) on the DIN rail. The C-curve means magnetic trip occurs at 5–10× In (315–630 A), which suits loads with a short inrush peak like small motors, transformers, or capacitor banks. Neutral conductor switching (1P+N) means the neutral is opened and closed with the phase, which is required in some regional wiring codes for single-phase final circuits. ## Panel integration At 2 width units (36 mm) and 55 mm installation depth, it leaves room for adjacent breakers or busbar feeders in a standard distribution board.","metaTitle":"SENTRON 5SQ2570-0KA63 MCB, 2-Pole 63A C-Curve, 3kA","metaDescription":"SENTRON 5SQ2570-0KA63 circuit breaker, 2-pole 1P+N, 63 A, C characteristic, 3 kA breaking capacity per EN 60898/IEC 60947-2, 240 V AC, 50 Hz.
