3-phase asymmetry, phase-sequence, phase-loss relay, 22,5mm Screw terminals

Monitors voltage asymmetry, phase sequence and phase loss for 3-phase 3-wire or 4-wire power supplies, in one unit.

  • Worldwide power specifications supported by one unit

  • Phase sequence, phase loss: operation reaction time 0.1s maximum

  • Asymmetry: operation time setting from 0.1 to 30s

  • Reset method: automatic

  • Power ON lock: 1s or 5s
