Supervisory Relays

Designed for use in automation and control systems to control asymmetry, phase direction and contactor contact activation in three-phase networks.

kwadrat  relays for the phase presence and direction control
kwadrat  designed for voltage range 1x230V AC / DC and 3 × 230 / 400V AC
kwadrat  changeover contact 1x8A
kwadrat  regulation of asymmetry threshold and delay times
kwadrat  measurement of the true effective value of the TrueRMS voltage
kwadrat  window and undervoltage functions
kwadrat  resistance monitoring resistors for PTC sensors
