Electric for rolling stock - Schaltbau - #14

The high-voltage switchgear ofpassenger coaches is integrated in these cabinets.The built-in disconnecting and earthing device ensures safe maintenance.

Mounted in the underframe ofthe rail vehicle the high-voltage switchgear is used for switching the power supply and the high-voltage heating instal­lation. Optional are components for adjusting the electrical configuration to the requirements ofcross-border traffic.

The new Schaltbau safety contactor ZH2000 combines main contactor and disconnecting and earthing function in one device.

Mounted in a high-voltage switchgear cabinet, the safety contactor oper­ates like any other main contactor. On opening the cabinet, a safety loop is being interrupted and the main contactor is switched offelectrically.

A special feature is that main contacts which may have become welded together are opened by mechanical force. After that the disconnecting and earthing operation is carried out.
