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) and commercial CT input

(0 to 1 A or 0 to 5 A) supported.

• Output status can be monitored using LED indicator.

• Inputs are isolated from the power supply.
