Product details

Siemens 5SJ4302-7HG41 is a 3-pole C-curve MCB, rated 10 kA and 15 kA at 400 V AC, 60 V DC max.

Mounting & panel fit

Any mounting position. Combined (tunnel/screw) terminals top and bottom; torque 3.5 Nm. IP20 (conductors connected) / IP40 (handle zone).

Compliance & environmental construction

Halogen- and silicon-free construction reduces outgassing and corrosion risk in sensitive process environments — relevant for petrochemical panel retrofits. The housing is sealable (lockable handle option). Vibration resistance tested to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz.
