The 3-pole design (3 MW, 54 mm wide) switches all three phases simultaneously, so it fits a standard 3-phase distribution board without a neutral pole. ## Mounting and integration — DIN-rail fit and panel constraints The 54 mm width (3 modular units) matches the standard 18 mm/module grid, so it occupies three adjacent positions. Mounting position is any — vertical, horizontal, or flat — which simplifies layout in tight sub-distribution boards. IP20 with connected conductors — finger-safe from the front but not washdown-rated. Sealable design (can be padlocked in OFF position) for lockout/tagout compliance.","metaTitle":"Siemens 5SL1363-7MB SENTRON MCB, 63A 3P C-Curve, 3kA","metaDescription":"Siemens 5SL1363-7MB SENTRON miniature circuit breaker, 63 A, 3-pole, C characteristic, 3 kA per IEC 60947-2.
