Single-phase Overcurrent/Undercurrent Relay [K8DT-AW] (Part Numbers)

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
• UL listed for easy shipping to North America
• Double-insertion holes for crossover wiring (all terminals)
• Models added with transistor outputs for superior contact reliability
• RoHS compliant
