... K8AB-AS2-J. When monitoring a device that has a large starting current such as a motor, use the K8AB-AS3-J. Adjust the number of conductor windings so that a minimum flows to the primary side of the K8AC-CT200L CT. Increasing the number of windings will simulate an increase in current. Minimize the operating time (0.1 s) for this application ...
