Rated operating voltage is 400 V AC for multi-phase operation, with a maximum of 440 V AC. Supply frequency is 50/60 Hz. The DC rating tops out at 72 V — usable for DC branch protection only at low voltage. The MCB is sealable, halogen-free, and silicon-free, which simplifies compliance for installations requiring low-corrosion or clean-room materials. ## Panel integration and mechanical fit Depth is 76 mm, height 90 mm, width 36 mm (2 MW). Mounting position is unrestricted — installs vertically, horizontally, or flat. IP20 with connected conductors, so the busbar area must be within a closed enclosure.","metaTitle":"Siemens 5SL4250-7CC SENTRON MCB, 2P C 50A 10kA","metaDescription":"Siemens SENTRON 5SL4250-7CC miniature circuit breaker, 2-pole, C-curve, 50 A, 10 kA breaking capacity per EN 60898 at 400 V AC.
