K8DT-AW2TA

New Product Single-phase Overcurrent/Undercurrent Relay K8DT-AW Detect errors in motors and other equipment through current changes. Monitor for overcurrents and undercurrents simultaneously with one Relay. Monitor AC or DC currents with one Relay. Use with commercially available CTs (CT secondary side: 0 to 1 A or 0 to 5 A). 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. For the most recent information on models Models added with transistor outputs for superior contact reliability. that have been certified for safety Refer to Safety Precautions on page 10. standards, refer to your OMRON website.
