At 72 mm wide, this breaker takes four DIN-rail width units — standard 18 mm per pole — so it fits a 4-module slot in any SENTRON distribution board or enclosure. The 76 mm depth plus 70 mm installation depth means it sits flush with the busbar stack; you don't need extra gutter space behind it. Wire it with solid or stranded copper from 0.75 mm² up to 25 mm², torqued to 2.5–3 N·m. That range lets you feed a 25 mm² incoming and branch out to 1.5 mm² on the load side without an adapter. That covers most indoor panels, including unventilated enclosures near process heat. The IP20 rating is standard for a DIN-rail device — it's finger-safe with conductors connected, but it expects to live inside a sealed enclosure, not out in the weather. Siemens lists this breaker for residential buildings and infrastructure — think lighting circuits, socket outlets, and small motor starters in commercial or light industrial panels. The halogen-free and silicon-free construction also suits it for environments where outgassing matters, like clean rooms or food processing areas.","metaTitle":"Siemens 5SL4603-6 SENTRON MCB, 4P 3A B-Curve 10kA","metaDescription":"Siemens 5SL4603-6 SENTRON miniature circuit breaker, 4-pole 3 A, B characteristic, 10 kA breaking capacity per EN 60898.
