The 54 mm width means it fills three 18 mm slots — standard for a 3-pole MCB in a SENTRON distribution board. Mounting position is any, so vertical or horizontal rail orientation works within the enclosure. IP20 with connected conductors — the terminals are finger-safe only when wired; the breaker itself is intended for inside a locked or tool-accessible enclosure, not exposed to washdown. ## Electrical and environmental ratings DC rated maximum is 72 V. Overvoltage category III, pollution degree 2 — standard for fixed-installation distribution panels. Halogen-free and silicon-free construction, sealable (can be locked in OFF position).","metaTitle":"Siemens 5SL4306-6 SENTRON MCB, 3P B 6A 10kA 400V","metaDescription":"Siemens 5SL4306-6 SENTRON miniature circuit breaker, 3-pole, B-curve, 6A, 10kA breaking capacity per EN 60898 & IEC 60947-2, 400V AC.
