CO3 and CO4 Series

High-voltage changeover unit for rail vehicles

Sensors and high-voltage controlgear

Schaltbau C03 and CO4 Series change-over units are designed for load-free switching of electrical loads. They are applied in rail vehicles which are used in cross-border service and are operated with different high-voltage power sources.

Required control signals are generated by the corresponding Schaltbau ZH1114 Series voltage selector .

Features

  • Load-free adjustment of electrical configurations to different networks, e.g. various train line voltages in accordance with UIC 550
  • Suitable for all UIC voltages up to 5 kV DC max.
  • Inexpensive high-voltage switch for applications requiring high
    conventional thermal current
  • Various control programmes available in accordance with the
    requirements of the European railway companies
  • Simple adaptation of control programme to new requirements
