12.1 MCU (Motor Control Unit)

12.1.1 Extract from the Technical Description

The switchgear can be equipped with different versions of the electrical motor control unit
(MCU, Motor Control Unit). The following sections are an extract from the Technical Description
of the electrical motor control unit.
The complete Technical Description of the different versions is available under the following

12.1.2 Application

The MCU controls the following motor operating mechanisms for three-position switches in
medium-voltage switchgear:
▪ Spring-operated mechanism
▪ Spring-operated/stored-energy mechanism
The MCU is equipped with a universal wide voltage range. It can optionally be connected to
different auxiliary and motor voltages. The auxiliary and motor voltages can be combined and do
not necessarily have to be identical.

NOTICE

Insufficient voltage quality

The functioning of the MCU may be impaired.
⇨ The voltage quality of the voltages used for auxiliary and load circuits must correspond

to applicable standards.

⇨ If an AC control or AC load voltage is used, which is generated directly from single-phase

inverters, earth U
