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
UL listed for easy shipping to North America
Double-insertion holes for crossover wiring (all terminals)
Models added with transistor outputs for superior contact reliability
