The D characteristic means it tolerates inrush peaks up to 10–14× rated current before tripping magnetically, making it the right choice for motor starter feeders, transformer primaries, or any load with a high starting surge. Thermal derating is published: at 40 °C ambient the continuous current drops to 30.31 A, at 50 °C to 28.52 A. ## DIN-rail footprint and integration Mounting position is unrestricted, so vertical or horizontal busbar orientation works. IP20 with connected conductors; the terminals are touch-protected per the product feature listing. No neutral pole switching — this is a 4-pole breaker protecting all four conductors, but the neutral is not switched independently.","metaTitle":"Siemens 5SL4432-8CC SENTRON MCB 4P D 32A 10kA 400V","metaDescription":"Siemens 5SL4432-8CC SENTRON miniature circuit breaker, 4-pole, D-curve, 32 A rated at 400 V AC, 10 kA breaking capacity per EN 60898.
