Suitability for residential buildings and infrastructure is stated, but the 10 kA SCCR and overvoltage category III also make it a common choice in commercial distribution boards and light industrial sub-panels. ## Ratings that matter for fit The 10 A rating at 30 °C derates to 9.24 A at 40 °C, 8.83 A at 45 °C, 8.41 A at 50 °C, and 7.96 A at 55 °C — so if the breaker lives in a warm enclosure or next to other heat sources, the actual continuous current it can carry drops. The 3-pole design with no neutral switching means it breaks all three phases but leaves the neutral through. The 3-module-width footprint (54 mm wide) and 76 mm depth fit standard DIN-rail enclosures.","metaTitle":"Siemens 5SL4310-8CC SENTRON MCB, 3P D 10A 10kA 400V","metaDescription":"Siemens 5SL4310-8CC SENTRON miniature circuit breaker, 3-pole, D-curve, 10 A, 10 kA breaking capacity at 400 V AC.
