Voltage monitoring relays with fixed range - HRN3-81

EAN: 8595188188821 | Code: 8882

DESCRIPTION

  • The relay is designed to monitor phase loss, sequence and asymmetry in 3-phase network.
  • Power supply from the monitored circuit.
  • Wide range of monitored voltage 208 – 480 V.
  • Adjustable time delay (to eliminate short-term voltage drops).
  • Measures true root mean square value of the voltage - TRUE RMS.
  • Adjustable level of asymmetry with the option to turn it off.
