Description:
YC9VA voltage and current display relay is a microprocessor-based voltage monitoring device for single-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 voltage and current display relay used in administrative, industrial and residential buildings and has the function of protecting
single-phase lines:
Surge protection;
Undervoltage protection;
Overvoltage protection;
Working under voltmeter mode.
