Product details

Rated operational current varies with voltage: 10 A at 24 V and 230 V, 4.7 A at 60 V, 3 A at 110 V and 400 V, 1.2 A at 220 V, 2 A at 500 V, 1 A at 690 V, 0.5 A at 440 V, and 0.26 A at 600 V. The coil draws 4 W DC both for closing and holding.

Terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded wire. Pollution degree 3 rating suits industrial environments with conductive pollution.

Compliance includes RoHS substance prohibitance dated October 1, 2009.
