New Product Three-phase Voltage and Phase-sequence Phase-loss Relay K8DT-PM Protect motors and other equipment from unstable LR voltages in the power supply system. Protect motors and other equipment by detecting overvoltages, undervoltages, 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 that reduce wiring work. For the most recent information on models The use of cage clamps enables wiring with bare stranded wires. that have been certified for safety Double-insertion holes for crossover wiring (all terminals). standards, refer to your OMRON website. UL listed for easy shipping to North America. Certified for maritime standards (LR). Models added with transistor outputs for superior contact reliability. Refer to Safety Precautions on page 9. Refer to pages 7 to 8 for commonly asked questions.
