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.
Refer to Safety Precautions for the K8AB
Series. Refer to page 9 for the Q&A section.
