That 10 kA figure is the fault current it can safely interrupt without welding contacts or cascading damage upstream, which is the standard residential and light commercial panel rating in most of Europe and Asia. The B-curve trips between 3 and 5 times rated current, so it's sized for resistive and general-purpose loads — lighting, small heaters, control transformers — not motor starts or high-inrush gear. ## Thermal derating and panel fit At 40 °C ambient the 13 A rating drops to 12.31 A; at 45 °C it's 11.96 A; at 55 °C it's 11.2 A. That means if this breaker lives in a crowded enclosure with other heat sources, the continuous load needs to stay under the derated number — not the 30 °C nameplate. The 3-pole body takes up 3 modular width units (54 mm wide, 76 mm deep, 90 mm tall) and snaps onto standard DIN rail. Mounting position is any, so vertical or horizontal rail orientation works. IP20 with connected conductors — fine inside a panel, not for wet locations. ## Construction details Sealable, halogen-free, and silicon-free construction — relevant for installations that require low outgassing (clean rooms, medical, or telecom shelters). Mechanical service life is 10,000 switching cycles typical. Overvoltage category III, pollution degree 2. Energy limitation class 3, which means it limits let-through energy to a level that protects downstream wiring in a fault.","metaTitle":"Siemens 5SL4313-6 SENTRON MCB, 3P B-Curve 13A 10kA 400V","metaDescription":"Siemens 5SL4313-6 SENTRON miniature circuit breaker, 3-pole, B-curve, 13A, 10kA breaking capacity at 400V AC.
