Breaking capacity is 10 kA per EN 60898 at 400 V AC, and the multi-phase rating goes to 440 V AC — enough for most industrial panel secondary distribution where the fault current at the sub-distribution board stays under 10 kA. ## Mounting and wiring — what fits Mounting position is any — vertical, horizontal, upside-down — no derating required for orientation. Terminals accept solid or stranded copper from 0.75 mm² up to 35 mm², with a tightening torque of 2.5 to 3.5 N·m. Combined terminal design at both top and bottom means the same clamp works for cable entry and busbar connection. The breaker is sealable and touch-protected with conductors connected.","metaTitle":"Siemens 5SY4632-8CC11 SENTRON MCB, 32A D-Curve, 4-Pole, 10kA","metaDescription":"Siemens 5SY4632-8CC11 SENTRON miniature circuit breaker, 32 A rated, D tripping characteristic, 4-pole (3P+N), 10 kA breaking capacity per EN 60898. 400 V AC, IP20.
