Product details

It uses screw-type terminals for both the main and auxiliary circuits, and the front panel carries an IP20 protection class. The relay is ATEX certified (DMT 98 ATEX G 001) for use in potentially explosive atmospheres.

The relay measures 87 mm high, 45 mm wide, and 78 mm deep. It is designed for stand-alone installation. The mounting position allows rotation of +/-135° on a vertical surface and tilting of +/-45° to the front and back. Lateral clearance to adjacent devices is 6 mm; no clearance is required upwards, forwards, backwards, or downwards.

Environmental and Electrical Ratings

It withstands 100% relative humidity during operation and shock loads of 8g for 10 ms. Power dissipation is 1.6 W per pole.

Main circuit terminals accept solid conductors: 1x (20...16 AWG), 1x (18...14 AWG), and 1x 12 AWG. For the auxiliary and control circuit, the screw terminals accept 2x (20...16 AWG) and 2x (18...14 AWG). Finely stranded conductors with core end processing are supported: 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²).
