DC rating tops out at 72 V, which covers 48 V control circuits but not 125 V DC battery banks. This is relevant for thermal coordination inside a sealed enclosure — adjacent devices must be spaced or derated if the internal ambient exceeds 40 °C. Installation depth is 70 mm, and overall dimensions (76 mm depth, 54 mm width, 90 mm height) match the standard SENTRON 3-pole footprint. The closest functional peer in the SENTRON family is the 5SL4363-7, which shares the same 3-pole C-curve, same dimensions (76 mm depth, 54 mm width, 90 mm height), and same 10 kA rating per IEC 60947-2. The 5SL4363-7 carries a higher power loss per pole (5 W vs 3.8 W) and a 10 kA EN 60898 rating versus the 6 kA on the 5SN6350-7CP. Both mount on the same DIN-rail footprint and accept conductors up to 35 mm² solid. For a panel originally specified around the 5SL4363-7, the 5SN6350-7CP drops in without rewiring — same pole count, same modular width, same installation depth.","metaTitle":"Siemens 5SN6350-7CP SENTRON MCB, 3-Pole, C-Curve, 10 kA IEC","metaDescription":"Siemens SENTRON 5SN6350-7CP miniature circuit breaker, 3-pole, C-curve, 6 kA per EN 60898, 10 kA per IEC 60947-2.
