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 Technology that reduce wiring work.
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.
• RoHS compliant.
Ordering Information
