Three-phase Voltage, Asymmetry, and Phase-sequence Phase-loss Relay
K8DT-PZ
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.
• 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 Blocks 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.
• Certification is pending for LR standards.
• Models added with transistor outputs for superior contact reliability.
