Single-phase Overcurrent/Undercurrent Relay [K8AK-AW] (Part Numbers)

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.
