The neutral conductor switching feature means the neutral pole opens and closes with the phases, which matters in TN or TT systems where you want the neutral isolated when the breaker is off. Any mounting position is permitted, so orientation in a tight enclosure isn't a constraint. ## Installation and environmental limits Terminals accept solid or stranded conductors from 0.75 to 25 mm²; tighten to 2.5–3 N·m. Ambient operating range is -25 to +55 °C with up to 95% humidity; storage range extends to -40 to +75 °C. Overvoltage category 3 and energy limiting class 3 are standard for main-distribution MCBs. The breaker is sealable, halogen-free, and silicon-free, which simplifies compliance in environments sensitive to outgassing.","metaTitle":"Siemens 5SL4608-8 SENTRON MCB, 4P D 8A 10kA 400V","metaDescription":"Siemens 5SL4608-8 SENTRON miniature circuit breaker, 4-pole (3P+N), D-curve, 8 A, 10 kA breaking capacity per EN 60898 & IEC 60947-2, 400 V AC.
