At 36 mm wide (2 width units), it occupies two adjacent DIN-rail positions in a consumer unit or sub-distribution board. The B characteristic (3–5× In) means this breaker will hold through the brief magnetizing inrush of a small transformer or a bank of LED drivers, but it trips faster than a C-curve on a hard short — a deliberate trade-off for circuits where the load current is predictable and the fault current path is short. For panels with a higher declared fault level, coordination with an upstream backup fuse or a current-limiting MCB is required. The 50 A rating on a 2-pole format suits sub-mains or high-current final circuits where single-pole switching is insufficient and a 2-module width is acceptable. ## Panel integration — DIN-rail mount, 2-module width, any position Mounting position is unrestricted — vertical, horizontal, or inverted — which simplifies layout in tight enclosures. Terminal capacity accepts 0.75 mm² to 25 mm², covering most final-circuit cable sizes up to 50 A. ## Compliance and approvals — EN 60898, overvoltage category III, touch protection Rated and tested per EN 60898 for the 7.5 kA breaking capacity. Overvoltage category III (distribution-board level) per IEC 60664. Touch protection is integrated — no live parts accessible with the breaker snapped onto the rail. Halogen-free and silicon-free construction, sealable for tamper-evident tagging. The 10 000 mechanical switching cycles cover typical residential and light commercial service life.","metaTitle":"Siemens 5SL6250-6RC SENTRON MCB, 50 A, 2-pole, B-curve, 7.5","metaDescription":"Siemens 5SL6250-6RC SENTRON miniature circuit breaker, 50 A rated, 2-pole, B characteristic, 7.5 kA breaking capacity per EN 60898.
