Product details

It carries 2 normally-open and 2 normally-closed instantaneous contacts, rated for switching at voltages from 24 V up to 690 V, with the current handling dropping as voltage rises: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. The 34 V DC coil draws 11 W to close and 4 W to hold, with an integrated varistor for surge suppression.

Wire termination accepts solid conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or 2x 4 mm² per terminal.

Environmental and endurance specs

Shock resistance is 10g for 5 ms and 5g for 10 ms — enough for most industrial machinery but not for high-vibration applications like crushers.
