Voltage monitoring relays with fixed range - HRN3-81

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.
