Contactor Unit CPS 12-7

Switch module with a nominal current of 400 A for isolated three-phase mains with a nominal voltage up to 6.6 kV. Vacuum switching tubes with a high breaking capacity make fuses superfluous. Integrated electronics assume all control functions for the module and all monitoring and protective functions for the upstream mains, as well as the outgoing switch or secondary circuit of the transformer controlled by the module.
