K8DT-PZ
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
- RoHS compliant
