With IP20 protection (finger-safe with conductors connected), it is intended for enclosed panel mounting, not open-wet locations. ## Thermal derating and selectivity The 32 A rating holds at 30 °C ambient but derates to 30.31 A at 40 °C and 27.58 A at 55 °C — a 14 % drop from the nameplate figure. For a panel running at 40 °C ambient, the effective continuous load limit is just over 30 A, not the full 32 A. That matters when coordinating with an upstream 40 A or 50 A device: the 5SL4432-6's 10 kA SCCR at 400 V gives headroom for most residential and light commercial fault levels, but the thermal derating curve must be factored into the load schedule.","metaTitle":"Siemens 5SL4432-6 SENTRON MCB, 4P B 32A 10kA","metaDescription":"Siemens 5SL4432-6 SENTRON miniature circuit breaker, 4-pole, B-curve, 32 A rated at 30 °C, 10 kA breaking capacity per IEC 60898 and IEC 60947-2.
