The K8DT-PM is a three-phase under/over voltage, phase sequence, and phase failure monitor. It protects motors and other equipment from unstable voltages, detecting phase sequence and phase failure on three-phase power supplies. It provides phase failure detection while the motor is running, has higher resistance to inverter noise, and features a compact 17.5 mm width to reduce space required in panels. The push-in plus terminal reduces wiring complexity, and it includes dual inlet holes for crossover wiring on all terminals.
