switching devices


depending on the execution (rated voltage, rated current, short circuit current) a MV vacuum contactor, a contactor with HH fuses or a vacuum circuit breaker will be used.

star point

depending on the execution (rated voltage, rated current, short circuit current) a MV vacuum contactor or a vacuum circuit breaker will be used.


the mains switching device with the motor protection relay is located in the MV distribution and is no constituent of the starter.


Description powder coated steel housing with lifting lugs, earthing terminal and earthing bolts at the incoming, suitable for fork lift transportation
colour RAL 7035 
protection class standard IP 3X ( up to IP 43 possible)
MV cable entry from below, with cable clamp support
LV cable entry from below


Dimensions and weights

Dimensions and weight of the starter are depending on the rated voltage, the rated current, rated short circuit current and the start current of the motor. Furthermore the size of the start transformer has a significant influence on the total dimensions. The size of the transformer will also be additonally determined by the start time and the start voltage, which are also related to the data of the driven machine. All our offers contain dimensions and weight of the respective starter.

The dimensions of the starter range between
  Width Depth Height  
minimum 1.000 1.200 2.000 mm
maximum 2.500 3.000 2.400 mm


The weights of the starter range between

minimum 600 kg      
maximum 10.000 kg      


Large starters are delivered in two units and will be mounted at site (a detailed manual will be provided on this).
