With the CP series Schaltbau is introducing an innovative concept to the switchgear market. The arc-handling is done exclusively by permanent-magnetic blowout. This patented technology ensures fully bi-directional breaking capability and a more compact design. For the first time the universal devices can be configured as NO/NC contactor, disconnector or changeover switch. This enables us to react flexibly to changing customer requirements. Features Innovative Design Easily configurable as NO/NC contactor, disconnector or changeover switch DC bi-directional or AC up to 60 Hz max. Exclusively permanent-magnetic blowout – no critical currents and low wear of main contact system thanks to effective arc-handling High making capacity, also as disconnector and changeover switch Low total cost of ownership, modular and compact Main contact system Conventional thermal current: 600 A/ 1,200 A/ 2,000 A Nominal voltage: 1,5 kV, 3 kV Double-break contacts 1 pole versions

  • changeover switches for DC and AC
  • Main contactor
