Technical Data of Electrical Control and Operating Devices

The switchgear panels have been designed on principle so as to permit manual operation.

The drive mechanisms of the individual switching devices can be equipped, depending on the specific customer‘s model, with additional electrical control and operating devices. These are defined in the switchgear-specific circuit diagram, refer to the switchgear documentation.

Component fitting options:

Motor-operated drive mechanism for the earthing switch control element
Blocking coil

The blocking coil helps to prevent manual actuation of the earthing switch. If the supply voltage has failed or is shut off, all blocking coils are in blocked position.
Auxiliary switches

Auxiliary switches are always actuated directly by the truck or by the switch shaft via an intermediate linkage. Their position always corresponds to that of the main contacts. The switching functions have been set in the factory according to the circuit diagram.
Micro-switches are used depending on the customized panel models.
