Single-phase Overvoltage/Undervoltage Relay
K8DT-VW
Detect abnormal voltages applies to equipment to
protect against equipment failure.
Monitor for overvoltages and undervoltages
simultaneously with one Relay.
• Monitor AC or DC voltages with one Relay.
• Settings for the operating value, hysteresis, and operating time.
• 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.
• Models added with transistor outputs for superior contact reliability.
