It carries an IP20 rating with connected conductors, meaning it's finger-safe only when wired; no gaskets, no outdoor exposure. ## What fits alongside it That means you can add remote tripping or status indication without re-wiring the load side. The closest functional sibling is the 5SL4363-7 — same 3-pole SENTRON form factor (same 54 mm width, 76 mm depth, 90 mm height), same 400 V AC rating, same 50 A current, but with a C-curve trip characteristic and a 10 kA breaking capacity instead of the B-curve and 6 kA here. If your circuit sees motor inrush or transformer energization, the C-curve sibling is the usual pick to avoid nuisance trips. The physical swap is a straight DIN-rail drop-in: same footprint, same wiring, same auxiliary accessory compatibility. The power loss per pole is 5 W on the C-curve version versus 4 W on this B-curve unit — negligible difference in a distribution board.","metaTitle":"Siemens 5SL6350-6 SENTRON MCB, 3P, B-Curve, 50 A, 6 kA","metaDescription":"Siemens 5SL6350-6 SENTRON 3-pole miniature circuit breaker, B-curve, 50 A, 6 kA per EN 60898/IEC 60947-2.
