The quick-assembly fastening system and any-position mounting simplify panel layout — no orientation restrictions when fitting into a crowded enclosure. ## Breaking capacity and compliance For UL 1077 / CSA C22.2 No. 235 supplementary protection applications, the rating is 5 kA — a different standard, not a downgrade; it reflects the UL test protocol for branch-circuit protection. Mechanical service life 10,000 operating cycles typical. ## Environmental and installation Humidity derating: max 95% RH at 55 °C, 35% at 75 °C. IP20 with connected conductors. Housing halogen-free and silicon-free. Sealable for tamper-evident applications.","metaTitle":"Siemens 5SY7425-8CC SENTRON MCB, 4P D 25A, 400V AC","metaDescription":"Siemens SENTRON 5SY7425-8CC miniature circuit breaker, 4-pole, D-curve, 25A, 400V AC, 15kA IEC breaking capacity.
