K8AK-AW3 24VAC/DC Omron

Single-phase Overcurrent/Undercurrent Relay K8AK-AW Ideal for Current Monitoring for Industrial Facilities and Equipment. Monitor for overcurrents and undercurrents simultaneously. Separate settings and outputs supported for overcurrents and undercurrents. Use commercially available CTs (CT current on secondary side: 0 to 1 A or 0 to 5 A). Manual resetting and automatically resetting supported by one Relay. Startup lock and operating time can be set separately. Two sets of SPDT output contacts, 5 A at 250 VAC (resistive load). Output status can be monitored using LED indicator. Inputs are isolated from the power supply. Refer to Safety Precautions on page 11. For the most recent information on models that have been certified for Refer to page 10 for commonly asked questions. safety standards, refer to your OMRON website.
