For a UL 1077 listing (supplementary protector duty), the interrupting rating is 5 kA. That's typical for North American branch-circuit applications where the upstream breaker already provides primary fault clearance. At 76 mm deep, 72 mm wide (4 modular width units), and 90 mm tall, it fits standard DIN-rail enclosures. The 70 mm installation depth gives you a bit of clearance behind the busbar. Combined top and bottom terminals simplify daisy-chaining — no need to re-terminate the supply side when adding downstream breakers. Neutral conductor is not switched internally (4-pole means all four poles are live/phase, no switched neutral). If you need a switched neutral, this isn't the variant — look at the 4-pole with neutral switching in the same family. The sealable option (yes) lets a panel builder lock the toggle position after commissioning, which keeps unauthorized hands off the trip setting.","metaTitle":"Siemens 5SY7425-7 SENTRON MCB, 4P C-curve, 15/25 kA, 76 mm","metaDescription":"Siemens 5SY7425-7 SENTRON 4-pole miniature circuit breaker, C-curve, 15 kA (EN 60898) / 25 kA (IEC 60947-2).
