Features of Three-phase voltage asymmetry and phase-sequence phase-loss relay OMRON K8DT-PZ series
Three-phase voltage asymmetry and phase-sequence phase-loss relay OMRON K8DT-PZ series:
- Phase loss detection while the motor is operating.
- Global power supply support. (Changed with a switch.)
- Greater resistance to inverter noise.
- Width of 17.5 mm to reduce space required in panels.
- Push-In Plus Terminal that reduce wiring work.
The use of cage clamps enables wiring with bare stranded wires.
Double-insertion holes for crossover wiring (all terminals).
- UL listed for easy shipping to North America.
- Certified for maritime standards (LR).
- Models added with transistor outputs for superior contact reliability
