Features

Three-phase voltage, asymmetry, and phase-sequence phase-loss relay

Protect motors and other equipment from unstable voltages in the power supply system. Detect overvoltages, undervoltages, voltage asymmetry, phase sequence, and phase loss for three-phase power supplies.

  • Phase loss detection while the motor is operating
  • Widely applies 3-phase 3-wire system (Changed with a DIP switch)
  • Greater resistance to inverter noise
  • Width of 17.5 mm to reduce space required in panels
  • Push-in plus Technology that reduce wiring work
  • Double-insertion holes for crossover wiring (all terminals)
  • Models added with transistor outputs for superior contact reliability
  • RoHS compliant
