Description
HRN3-81 | Voltage monitoring relays in 3P with adjustable levels
- The relay is designed to monitor undervoltage (HRN3-80), phase loss, sequence and asymmetry in 3-phase network.
- Power supply from the monitored circuit.
- HRN3-80: Monitors the drop below the lower voltage level (Umin).
- HRN3-80: The lower level of Umin is set in % of the selected range.
- 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.
