Product details

It also includes phase failure detection, so a lost phase won't leave the motor running single-phased.

Any mounting position is permitted. Dimensions: 55 mm wide, 140 mm tall, 149 mm deep — the width occupies three standard 17.5 mm modules, so panel fill is straightforward. Side clearance of 10 mm and vertical clearance of 50 mm (both upwards and downwards) keeps heat dissipation predictable. Main contact terminals accept M6 bolts; the control circuit terminals accept 2× (0.5 … 1.5 mm²) or 2× (0.75 … 2.5 mm²) solid or stranded wire.
