Rated insulation voltage (Ui) 440 V AC covers common 400 V three-phase systems with safety margin. Dimensions of 54 mm width (3 modular units), 70 mm depth, and 110 mm height fit standard DIN rail and leave room for adjacent breakers and wiring in a crowded enclosure. Sealable, halogen-free, and silicon-free construction suits food processing, medical, and cleanroom environments. Mounting position any, and IP20 with conductors connected (IP40 in handle area) allows flexible orientation inside a metal enclosure. Terminal tightening torque 3.5 Nm for copper conductors.","metaTitle":"Siemens 5SJ4305-7HG41 SENTRON MCB, C-curve 10 kA","metaDescription":"Siemens SENTRON 5SJ4305-7HG41 miniature circuit breaker, C-curve, 3-pole, 10 kA breaking capacity per EN 60898.
