Rated for 400 V AC, 60 V DC, and sealed against dust; halogen- and silicon-free construction. The breaker mounts on standard DIN rail, any orientation, and survives 50 m/s² vibration at 25-150 Hz, so it won't nuisance-trip on a shaky panel next to a VFD or conveyor drive. ## Panel fit & integration Three modular units wide (54 mm), 70 mm deep, 110 mm tall — drops into any standard 3-pole slot on a DIN rail. IP20 with conductors connected; handle area reaches IP40. Two separate mounting positions are acceptable, which helps when cable entries force a rotated rail.","metaTitle":"Siemens SENTRON 5SJ4340-7HG41 MCB, 3P C-curve, 10/15kA","metaDescription":"Siemens 5SJ4340-7HG41 SENTRON miniature circuit breaker, 3-pole C-curve, 10 kA (EN 60898) / 15 kA (IEC 60947-2), active production.
