Single-phase Current Relay

K8DT-AS

Detect errors in motors and other equipment

through current changes.

Use in either overcurrent or undercurrent mode.

• 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).

• Settings for the operating value, hysteresis, startup lock time, 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.

Ordering Information

Single-phase Current Relay

* The K8DT-AS3@@ is designed to be used in combination with an OMRON K8AC-CT200L Current Transformer (CT). (Direct input is not possible.)

OMRON CT

Commercially Available CTs

*

* If you use a commercially available CT, do not exceed the overload

capacity of the K8DT-AS2.
