In at least one embodiment, a modified contactor is used as a contactor in the starting device.

Method of manufacturing a starting device for a three phase electric motor, and a starting device

A cooling arrangement is disclosed for electrical components which are arranged in a housing of a soft starter which in particular may be designed for operation of an electric motor. In at least one embodiment, the cooling arrangement includes at least one fan arranged inclined in an opening in a housing wall such that the rotation axis of the fan is at an angle to the normal to the housing wall.
