It's built for residential and infrastructure branch-circuit protection — think lighting, socket outlets, and small loads where the inrush isn't severe but you still need a solid short-circuit interrupt. The C-curve (5-10x In) means it holds through motor and capacitive inrush but trips fast on a hard fault. At 2 A, it's sized for smaller final circuits, not main feeders. The maximum operating voltage for multi-phase operation is 440 V AC, so it's comfortable on 400 V three-phase panels with some headroom. Thermal derating is published: at 40 °C ambient it carries 1.92 A, at 45 °C it's 1.88 A, and at 55 °C it drops to 1.79 A. If the panel runs hot, factor that in. Sealable, halogen-free, and silicon-free construction.","metaTitle":"Siemens 5SL4402-7 SENTRON MCB, 4P C-Curve 2A, 10kA 400V","metaDescription":"Siemens SENTRON 5SL4402-7 miniature circuit breaker, 4-pole, C-curve, 2A, 10kA breaking capacity at 400V AC.
