It breaks fault currents up to 10 kA per both EN 60898 and IEC 60947-2 — that's the standard residential and light-commercial interrupting rating, so it clears a dead short without welding contacts. The B curve (3–5× In instantaneous trip) suits resistive and general-purpose loads where you want nuisance-free protection for lighting, receptacles, and small appliances.","metaTitle":"Siemens 5SL4525-6 SENTRON MCB, 25A, 1P+N, B-Curve, 10kA","metaDescription":"Siemens SENTRON 5SL4525-6 miniature circuit breaker, 25 A, 1P+N, B characteristic, 10 kA per EN 60898/IEC 60947-2, 230 V AC, 2 MW wide.
