Siemens 5SJ4104-7HG41 SENTRON MCB — C-curve, 1-pole, 10/15 kA
Its C-curve tripping characteristic (magnetic trip at 5–10× In) makes it suited for moderate inrush loads like motor starters and contactor coils, where the short-duration surge stays below the magnetic threshold but a hard fault clears within the 10 kA interrupting rating per EN 60898, or 15 kA per IEC 60947-2 at 400 V AC. 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.
