It carries a continuous rated current of 20 A and is rated for 7.5 kW motor loads at 400 V AC, which puts it squarely in the mid-range of the SIRIUS 3RV family for typical three-phase induction motors up to that power class. At 240 V it jumps to 100 kA, and it still holds 10 kA at 500 V and 4 kA at 690 V, so it's not a one-voltage pony.
Screw-type terminals on both main and auxiliary/control circuits accept solid and stranded conductors: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²), or AWG 14 to 10 for the main contacts. Zero clearance needed at the back or sides — 0 mm backwards and at the side — so you can pack it tight against other devices on the rail.
RoHS compliance date marked as 01.05.2012, so it meets the EU substance restrictions. Shock rated at 25g for 11 ms — tough enough for industrial machinery vibration.
