Its 4.5 kA breaking capacity per EN 60898 (and matching IEC 60947-2) covers the fault current available at most residential and infrastructure service entrances — the standard rating for a 63 A final-circuit breaker in a domestic distribution board. ## DIN-rail footprint and wiring Occupies a single 18 mm width unit on standard DIN rail. The 90 mm height and 76 mm depth (70 mm installation depth) fit flush in a 4-module enclosure with room for the outgoing cables. Screw terminals accept 0.75–25 mm² solid or stranded copper — enough for a 16 mm² feed on the line side and a 25 mm² load-side tail if needed. Mounting position is unrestricted, so the breaker can be installed horizontally in a shallow gland plate if the enclosure depth is tight. IP20 with connected conductors (finger-safe once wired). Rated ambient -25 to +45 °C, with periodic tolerance to +55 °C and 95% humidity. Overvoltage category III, energy limiting class 3. Sealable for anti-tamper applications. No neutral conductor switching function — this is a straight 1-pole line breaker.","metaTitle":"Siemens 5SL3163-7 SENTRON MCB, 1P C 63A 4.5kA 400V","metaDescription":"Siemens 5SL3163-7 SENTRON miniature circuit breaker, 1-pole, C-curve, 63 A, 4.5 kA breaking capacity per EN 60898, 400 V AC.
