The 2-module width (36 mm) and 76 mm depth fit standard DIN-rail enclosures; the quick-assembly fastening system and any-position mounting simplify panel integration. Ambient temperature derating is published: at 50 °C the continuous rating drops to 24.38 A, at 55 °C to 23.72 A. IP20 with connected conductors is standard for enclosed panel mounting. ## Compliance and approvals The product designation per IEC 81346-2 and EN 61346-2 is letter F. Sealable terminals are standard, allowing lockout-tagout compliance.","metaTitle":"Siemens 5SY8225-7 SENTRON MCB, 2P 25A C-Curve, 30kA IEC","metaDescription":"Siemens 5SY8225-7 SENTRON miniature circuit breaker, 2-pole 25 A, C characteristic, 30 kA breaking capacity per IEC 60947-2.
