ZH1500 series

Disconnecting and earthing device for single and multi-system rail vehicles

ZH1500 series
Disconnecting and earthing device

The equipment is designed for all UIC voltages, from 1 kV AC up to 3 kV DC.
The equipment usually is built in behind a door und connected to that door via a rod. Opening of the door pulls the rod and disconnects the connection between the train bus bar and the power supply. The power supply is then connected to ground to allow safe access to the switch gear. This grounded state may be secured with up to 3 locks to prevent a second person to unintentionally connect the power supply again.

The contact system is designed for switching without load but allows some emergency switchings. Under normal operating conditions the main contactor “energy” is being switched off prior to the opening of the contacts via a door switch.

Features
