At 40 °C it derates to 9.27 A; at 50 °C to 8.5 A; at 55 °C to 8.04 A. If your panel internal ambient runs hot — say a crowded enclosure with drives — size the upstream protection for the derated value, not the 35 °C sticker. The operating range spans -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, tapering to 35% at 75 °C. That covers most indoor industrial environments including unheated warehouses. Mounting position is any orientation. The combined terminal top and bottom (both accessible) makes daisy-chaining or looping feed-through straightforward in a multi-pole assembly. Designed to IEC / EN 60947-2, overvoltage category III, pollution degree 3. Halogen-free and silicon-free construction.","metaTitle":"Siemens 5SY4310-7CV MCB, 3P C-10A 15kA IEC 60947-2","metaDescription":"Siemens 5SY4310-7CV miniature circuit breaker, 3-pole C-curve, 10 A rated, 15 kA breaking capacity per IEC 60947-2.
