Single-phase Current Relay
K8AB-AS
Ideal for current monitoring for industrial
facilities and equipment.
• Monitor for overcurrents or undercurrents.
• Manual resetting and automatically resetting supported by one
Relay.
• Startup lock and operating time can be set separately.
• One SPDT output relay, 6 A at 250 VAC (resistive load).
• Output relay can be switched between normally open and
normally closed.
• Process control signal (4 to 20 mA) supported.
• Commercial CT input signal (0 to 1 A, 0 to 5 A) supported.
• Output status can be monitored using LED indicator.

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 ...
