Product details

It is rated 27 A at 480 V and 15 kW at 400 V (AC-3), making it a direct fit for reversing motor loads up to that current — think conveyors, hoists, or any application needing forward/reverse switching without external interlocks.

The assembly occupies 90 mm width, 101 mm height, and 97 mm depth — plan for that footprint in the panel layout.

Solid wire capacity: 2x (1... 2.5 mm²) and 2x (2.5... 10 mm²). Stranded: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²). The magnet coil also terminates at screw terminals. Keep the strip length consistent with the terminal design — no push-in or spring-cage here.

Frequently asked questions

What are the key ratings for this reversing contactor assembly?
