The 2-module-width (36 mm) body snaps onto standard DIN rail — any mounting position works. The SENTRON 5SL series is a broad family; the 5SL4201-6 is the 2-pole 1 A B-curve variant. If you're holding a BOM that calls out this exact order code, it's the active line item — no substitution needed. ## Integration and ratings IP20 with conductors connected, so it's panel-only, not field-exposed. Sealable terminals are standard, and it's halogen-free and silicon-free for environments sensitive to off-gassing. Derating matters: at 30 °C it's 1 A, at 40 °C it drops to 0.96 A, at 55 °C to 0.9 A. Mechanical life is 10 000 cycles typical. Installation depth is 70 mm (the can depth behind the rail).","metaTitle":"Siemens 5SL4201-6 SENTRON MCB, 2P B-Curve 1A 10kA","metaDescription":"Siemens 5SL4201-6 SENTRON miniature circuit breaker, 2-pole, B-curve, 1A rated at 400V AC, 10kA breaking capacity per EN 60898.
