K8DT-PM

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

Protect motors and other equipment from unstable voltages in the power supply system. Protect motors and other equipment by detecting overvoltages, undervoltages, 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
RoHS compliant
