switching devices
| by-pass |
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. |
| remark |
the mains switching device with the motor protection relay is located in the MV distribution and is no constituent of the starter. |

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 |
