High Power Contactor Unit HPC 450-1

Contactor module for high-output three-phase drives or outgoing circuits in power mains with up to 1.1 kV nominal voltage. The integrated electronic components assume all control, monitoring, and protective functions. The high breaking capacity of the vacuum switching tube makes power fuses superfluous. With the motorised phase inversion switch, the direction of rotation of the mains at the outgoing circuit is changed within seconds without the line connections having to be changed.
