It is designed for residential and infrastructure branch-circuit protection — think distribution boards in apartment blocks, light commercial, or utility sub-mains where the fault level stays under 7.5 kA. On the DC side it is rated up to 72 V, so it can also serve as a DC branch protector in a telecom or solar combiner box fed from a 48 V or 60 V bus. The 7.5 kA breaking capacity per EN 60898 is the standard for most residential and light commercial distribution boards in Europe and Asia — it safely interrupts a fault up to 7.5 kA at 415 V AC without welding the contacts or cascading damage upstream. If your installation's prospective short-circuit current (PSCC) at the breaker terminals exceeds 7.5 kA, step up to a 10 kA or 15 kA rated MCB from the same SENTRON family. For a 4-pole breaker that is 8.8 W total dissipated inside the enclosure — negligible for a single unit, but worth summing if the board packs twenty of these in a sealed cabinet with no forced ventilation. That is fine for a distribution board seeing a few operations per year; for a frequent-switching application (e.g., a lighting contactor replacement), use a dedicated contactor instead. Frequency range is 50/60 Hz — no derating needed for 50 Hz vs 60 Hz mains.","metaTitle":"Siemens 5SL6425-7RC SENTRON MCB, 25A 4P C-Curve, 7.5kA","metaDescription":"Siemens SENTRON 5SL6425-7RC miniature circuit breaker, 25A, 4-pole, C characteristic, 7.5 kA breaking capacity per EN 60898.
