Abstract

When manufacturing a starting device for a three-phase electric motor, especially a soft starter, in at least one embodiment an arc quenching system is at least partly removed from a commercially available contactor that so becomes to a modified contactor. In at least one embodiment, a modified contactor is used as a contactor in the starting device.
