Product details

Rated for 690 V, it handles motor loads up to 3 kW at 400 V, 4 kW at 500 V, and 5.5 kW at 690 V. The auxiliary switch is integrated, and the main circuit connects via spring-loaded terminals.

The trip class is CLASS 10. The relay's own dissipation is 2.2 W per pole. The spring-loaded terminals accept 2× (0.5 to 2.5 mm²) solid or stranded.

Mounts in any position — stand-alone installation, no special clearance required. Dimensions are 102 mm high, 45 mm wide, 79 mm deep. The screwdriver slot takes a 3 mm diameter shaft, tip size 3.0 × 0.5 mm. Temperature-compensated from -40 to +60 °C, so it's fine in unheated cabinets or near process heat.

Frequently asked questions

What terminals does it use?

Spring-loaded terminals for the main current circuit, accepting 2× (0.5 to 2.5 mm²) solid or stranded wire.
