Breaking capacity is 15 kA per EN 60898 and 25 kA per IEC 60947-2, with a DC rating of 15 kA per IEC 60947-2 and 5 kA under UL 1077 / CSA C22.2 No. 235. The 25 kA IEC figure gives headroom for high-fault installations — industrial panels with large transformers upstream. IP20 with conductors connected — fine inside a closed panel, not for wet environments. Combined terminals top and bottom, sealable, halogen-free and silicon-free construction. Pollution degree 3, overvoltage category III. The sealable feature matters for installations that need tamper evidence — utility meters, rental equipment, or safety-critical circuits.","metaTitle":"Siemens 5SY7525-8 SENTRON MCB, D Curve, 25 A, 15 kA","metaDescription":"Siemens 5SY7525-8 SENTRON miniature circuit breaker, 2-pole 1P+N, D tripping characteristic, 25 A rated current, 15 kA (EN 60898) / 25 kA (IEC 60947-2) breaking capacity.
