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
• 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
