Sepecial feature of MC3-S
The innovation of this switchgear is the movable contact to create the isolating distance.
Switching compartment:
In the switching compartment the switching component is fix mounted to the baseplate. The position indicator and operating elements of the switch component are directly integrated into the High-Voltage-Door.
The connections of the switching component are conducted through a standard-duct onto the rear contacts. The ceation of the isolating distance occurs through moving the contacts.
The switch position indicator is mechanically coupled with the motor behind the front.
