Product details

Interrupt capacity and trip curve

Voltage ratings and pole configuration

Rated 400 V AC and 60 V DC, the 3-pole design (3P) switches all three phases simultaneously — no neutral conductor switching, so it is intended for three-phase loads or as a three-phase disconnect where the neutral is bonded elsewhere.

Mechanical integration and environmental limits

Snap-on mounting to standard 35 mm DIN rail; 54 mm width (3 modular units) and 70 mm depth leave room for adjacent devices in a crowded panel. Installation depth matches the 70 mm dimension — no extra clearance behind the rail. Vibration resistance tested to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz for 4 seconds, so it holds up on conveyor drives and compressor skids.

Frequently asked questions

What is the interrupt rating of the 5SJ4320-7HG41?

The interrupt capacity is 10 kA per EN 60898 for residential/light commercial circuits and 15 kA per IEC 60947-2 for industrial panel applications. Both ratings are declared on the same 3-pole C-curve device.
