The 15 kA breaking capacity at 400 V (per IEC 60947-2) tells you it can safely interrupt a short-circuit fault up to that level without welding contacts or cascading upstream — important for selectivity in a distribution panel. Under UL 1077 / CSA C22.2 No.235 it's rated 5 kA, so if the installation falls under North American supplementary protection rules, that's the figure to coordinate with. The 18 mm width (one modular unit) and 76 mm depth fit standard DIN-rail enclosures. Terminal range accepts 0.75 to 35 mm² solid or stranded — covers most panel wiring from control circuits to feeder taps. Ambient temperature range is -25 to +55 °C, with humidity derating above 55 °C.","metaTitle":"Siemens 5SY7150-8CC SENTRON MCB, 1P, 50 A, D Curve, 15 kA IE","metaDescription":"Siemens SENTRON 5SY7150-8CC miniature circuit breaker, 1-pole, 50 A, D tripping characteristic, 15 kA breaking capacity at 400 V AC.
