Product details

Coil termination is via screw-type terminals, and the main power circuit accepts stranded conductors from 70 to 240 mm².

Dimensions are 210 mm high, 145 mm wide, and 202 mm deep. Mounting is by screw fixing through an 11 mm diameter hole. The mounting position allows a vertical surface with +/-90° rotation or +/-22.5° tilt forward and back, giving flexibility in tight enclosures. These are the minimum air gaps for heat dissipation and arc containment.

Wire Termination Details

Auxiliary circuits accept solid or stranded wires: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). Up to 4 auxiliary contacts can be attached.

Switching Performance

Arcing time is 10-15 ms. At 50 Hz the power factor is 0.9; at 60 Hz the range is 0.8 to 1.1. The coil initial power factor is 0.8, with a full-scale value of 1.1.
