Motor starters – tool-less plug connection

The tool-less plug connection technology features drastically reduced mounting and wiring times by tool-less combination of standard components to form motor starters.

The tool-less plug connection provides the user with an optional neutral interface within the proven PKZM 0 motor-protective circuit-breaker and DIL M contactor switchgear areas in current ranges up to 12 A for system plug-in components, without extra cost.

The optional interface facilitates connection of the respective auxiliary and main circuit contacts to the switchgear.
 

The tool-less plug connection provides the basis for innovative and customized solutions

The direct-on-line starter is a complete unit consisting of a PKZM 0 motor-protective circuit-breaker and a DIL M contactor.

Both of the switchgear devices are mechanically interconnected via a plug-in connection element. A plug-in contact element originating from tool-less plug connection technology establishes the electrical connection between the motor-protective circuit-breaker and the contactor.

The switchgear combination can be mounted thereafter on the top-hat rail without adapter requirement. If the electrical connector is removed, visible isolation gap can be seen.
