Voltage and current display relay is a microprocessor-based voltage monitoring device for sinale-phase AC networks to protect electrical equipment from surge voltage. The device analyzes the main voltage and displays its curent 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.
Voltage 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.
