On backorder

The relay XN2 of the easy PROFESSIONAL LINE is a universal mains decoupling relay and contains the protective functions required for the mains parallel operation of power stations:

  • Over- and undervoltage protection
  • Over- and underfrequency protection
  • Phase sequence supervision
  • in addition, for the XN2-1: vector surge (fast decoupling of the generator in case of mains failure)
