System changeover switch

System changeover switch

Other countries, other voltages.

The overhead contact line in Switzerland has a voltage of 15 kilovolts and must switch over the system when it crosses to a different grid, for example, to Italy (3 kV). This manual solution allows you to continue driving without any faults with our Richard AG system changeover switch.
