It carries a 10 kA breaking capacity under both EN 60898 and IEC 60947-2, which means it can safely interrupt fault currents up to that level on a 400 V line without upstream cascading. The C-curve trips between 5× and 10× rated current — suited for mixed resistive and moderate inductive loads like general-purpose branch circuits in residential or light commercial infrastructure. ## Panel fit and integration Occupies one modular width unit (18 mm) on standard DIN rail. Depth of 76 mm and installation depth of 70 mm leave clearance for wiring behind the gland plate. IP20 with connected conductors — protected against finger contact but not washdown; intended for enclosed distribution boards. Mounting position is any, so it can be oriented vertically or horizontally inside the panel without derating the 63 A rating. ## Key ratings in context Rated for 50/60 Hz supply. Overvoltage category III and pollution degree 2 — standard for fixed-installation distribution boards. Power loss is 5 W per pole at rated current in hot operating state, relevant for thermal budgeting inside a multi-pole enclosure. The breaker accepts supplementary devices (auxiliary contacts, shunt trips, undervoltage releases) on the side, so it can be expanded for remote signaling or emergency-off functions without swapping the base unit.","metaTitle":"Siemens 5SL4163-7 SENTRON MCB, 1-Pole C 63 A 10 kA","metaDescription":"Siemens SENTRON 5SL4163-7 miniature circuit breaker, 1-pole, C-curve, 63 A, 10 kA breaking capacity per EN 60898/IEC 60947-2.
