It occupies 4 modular width units — standard 18 mm per unit, so 72 mm total. Installation depth is 70 mm; total depth is 76 mm. The top and bottom terminals are combined, meaning the same terminal accepts both the busbar and the outgoing conductor. Rated IP20 with connected conductors — fine inside an enclosure, not for wet washdown areas. Halogen-free and silicon-free matters if you're placing it in a sealed cabinet near sensitive electronics or in a clean-room zone where outgassing is a concern.","metaTitle":"Siemens 5SY6425-7CC SENTRON MCB, 25A 4P C-Curve 6kA","metaDescription":"Siemens 5SY6425-7CC SENTRON miniature circuit breaker, 4-pole, 25 A, C-curve, 6 kA breaking capacity per EN 60898.
