The Siemens SENTRON 5SL3125-6 is a 1-pole miniature circuit breaker rated 25 A with a B tripping characteristic. It breaks fault currents up to 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, which covers the majority of residential and light-commercial distribution boards.
Occupies 1 modular width (18 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm.
Rated 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 at 230/400 V AC.
Yes — both share the same 1-pole, 18 mm wide DIN-rail footprint, same depth and height. The difference is the trip curve: B on the 5SL3125-6 versus C on the 5SL6120-7. If the panel's selectivity study calls for a C-curve, swapping to a B-curve may cause nuisance tripping on motor or transformer starts.
