Rated 40 kA breaking capacity per IEC 60947-2 at 400 V AC, with a DC-side rating of 15 kA at 60 V (max 72 V). For UL 1077-listed applications (supplementary protection in North America), it's rated 5 kA. The 4-module width (72 mm) and 76 mm depth fit standard distribution enclosures. Approvals include IEC/EN 60947-2 and UL 1077, covering both IEC and North American supplementary protection applications. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Mechanical life 10 000 operating cycles typical. ## How it compares to the 5SY4101-7CV The 5SY4101-7CV is the closest functional sibling — same 4-pole, C-characteristic, SENTRON family. The key difference is breaking capacity: the 5SY8410-7 delivers 40 kA per IEC 60947-2, where the 5SY4101-7CV is rated lower (typically 10 kA or 15 kA, depending on variant). If your panel's fault current at the distribution point exceeds 15 kA, the 5SY8410-7 is the correct choice. Panel footprint and wiring are identical — same 4-module width, same DIN-rail mount — so it drops in without rewiring.","metaTitle":"Siemens 5SY8410-7 SENTRON MCB, 4P C-Char, 40 kA IEC","metaDescription":"Siemens 5SY8410-7 SENTRON 4-pole MCB, C characteristic, 40 kA breaking capacity per IEC 60947-2, 5 kA per UL 1077.
