The 18 mm width (1 modular unit) snaps onto standard DIN rail per EN 60715, and the combined top/bottom terminals accept Cu conductors at 3.5 Nm torque. Rated for AC 400 V and DC 60 V, with an insulation voltage (Ui) of 440 V AC. ## Sourcing & lifecycle — active, quoted to order For compliance documentation, the 5SJ4 series is designed to EN 60898 and IEC 60947-2, and halogen-free and silicon-free construction supports clean-room and sensitive-electronics environments. ## Fit and mounting — 1 MW, DIN-rail, any position Height is 110 mm. Mounting position is unrestricted — vertical, horizontal, or inverted — which simplifies layout in tight gland-plate zones. Vibration resistance to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s) covers most machine-mounted applications without supplementary bracing.","metaTitle":"Siemens 5SJ4104-7HG41 SENTRON MCB, 1P C-curve, 10 kA","metaDescription":"Siemens 5SJ4104-7HG41 SENTRON miniature circuit breaker, 1-pole, C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2.
