Features of Three-phase asymmetry and phase-sequence phase-loss relay OMRON K8AK-PA series
Three-phase asymmetry and phase-sequence phase-loss relay OMRON K8AK-PA series:
- Ideal for 3-phase voltage asymmetry monitoring for industrial facilities and equipment.
- Greater resistance to inverter noise.
- Monitor voltage asymmetry, phase sequence, and phase loss for three-phase 3-wire or 4-wire power supplies with just one Unit. Switch setting for 3-phase 3-wire or 3-phase 4-wire power supply.
- One SPDT output relay, 5 A at 250 VAC (resistive load).
- World-wide power specifications supported by one Unit (switchable).
- Relay status can be monitored using LED indicator.
