Product DescriptionGeneral YC9VA-3 voltage and current display
relay is a microprocessor-based voltage monitoring device for
three-phase AC networks to protect electrical equipment from surge
voltage.The device analyzes the main voltage and displays its
current value on a digital indicator.Load is switched by
electromagnetic relay.The user can set the current voltage value
and delay time through the button. The value is stored in
non-volatile memory. Aluminum wires and copper wires can be used
for connection. Application YC9VA-3 three and current display relay
used in administrative, industrial and residential buildings and
has the function of protecting single-phase lines: Undervoltage
protection; Overvoltage protection; Working under voltmeter mode;
Overcurrent proteciton. ParameterDataRated power supply
