Single-phase overcurrent/undercurrent relay Omron K8AK-AW series
Series: Single-phase overcurrent/undercurrent relay Omron K8AK-AW series
Features of Single-phase overcurrent/undercurrent relay OMRON K8AK-AW series
Single-phase overcurrent/undercurrent relay OMRON K8AK-AW series:
- 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 1A or 0 to 5A)
- Manual resetting and automatically resetting supported by one relay
- Startup lock and operating time can be set separately
- Two sets of SPDT output contacts, 5A at 250VAC (resistive load)
- Output status can be monitored using LED indicator
- Inputs are isolated from the power supply
