The 72 V DC maximum rating means it can also be used in DC control circuits, though the DC breaking capacity is not separately listed — treat it as suitable for low-energy DC loads only. Mounting position any. Combined terminal top and bottom means you can feed from either end without reconfiguring. Rated per EN 60898 (6 kA) and IEC 60947-2 (15 kA). Also carries a UL 1077 and CSA C22.2 No. 235 rating at 5 kA — that is the supplementary protector rating for North American panels. Halogen-free and silicon-free construction. Sealable for lockout/tagout. Touch protection on the terminals. Ambient temperature range -25 to +55 °C; storage -40 to +75 °C.","metaTitle":"Siemens 5SY6225-8 SENTRON MCB, 25 A, 2-Pole, D Curve, 400 V","metaDescription":"Siemens 5SY6225-8 SENTRON miniature circuit breaker, 25 A rated, 2-pole, D tripping characteristic, 400 V AC, 6 kA (EN 60898) / 15 kA (IEC 60947-2).
