Product details

What this Dahlander combination does

It is wired for AC operation with electrical interlocking between the two contactor paths, preventing both windings from being energized simultaneously — critical for Dahlander (consequent-pole) motor control where the low-speed and high-speed contactors must never close together.

This part is a phased-out product. The official successor is the SIRIUS 3RA2 series.

The screw terminals accept up to the wire sizes typical for 11 kW motor circuits. Electrical interlocking is internal to the combination — no external auxiliary contactors or wiring logic needed for the Dahlander safety interlock.
