The 3P+N pole design (4 poles total) makes it a three-phase-plus-neutral unit, sized for residential and infrastructure branch circuits where the neutral is switched alongside the phases. At 0.3 A, this is a very low-rated D-curve MCB, suited for protecting control transformers or instrumentation supplies rather than power circuits. ## Breaking capacity and voltage ratings Multi-phase operation is rated up to 440 V AC maximum. The overvoltage category is III (fixed installation), with pollution degree 2. For DC applications, the maximum rated voltage is 72 V. Thermal derating is published: 0.3 A at 30 °C, 0.28 A at 40 °C and 45 °C, 0.27 A at 50 °C, and 0.26 A at 55 °C. Height is 90 mm. Protection class is IP20 with connected conductors.","metaTitle":"5SL4614-8CC SENTRON MCB, 3P+N, D-curve, 0.3 A, 10 kA","metaDescription":"Siemens 5SL4614-8CC SENTRON miniature circuit breaker, 3P+N, D-curve, 0.3 A, 10 kA at 400 V AC.
