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
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.
