HYCRU8 Series Three Phase Voltage Protection Relay

Model:HYCRU8/HYCRU8S
Item:Three Phase Voltage Protection Relay
Voltage:60V-500V
Display Method:Indicator/Rotary/LED
Availability:
  • HYCRU8/HYCRU8S

  • CSQ


Three Phase Voltage Protection Relay

It is suitable for AC circuits with a frequency of 50/60Hz. When the main circuit of the equipment has abnormal conditions such as wrong phase (reverse phase), open phase, overvoltage and undervoltage, andvoltage imbalance, the control loop will be disconnected in time, and the protection will be fast and reliableterminal electrical equipment.
