CNC Overvoltage & Undervoltage Protector, 63A, 3-phase

Voltage and current control relay, 63A, 3-phase


Features:
Voltage and current display relay is used to protect 3-phase electrical equipment from overvoltage, undervoltage or overcurrent.
Automatic overvoltage and undervoltage protector is suitable for three-phase AC 380V line with a rated operating current up to 63A.
This is a microprocessor-based voltage monitoring device for single-phase AC networks to protect electrical equipment from damage.
The device analyzes the main voltage and displays its current value ??on a digital indicator.
The device will continuously analyze the voltage in the circuit, and if the voltage exceeds the set limit, the device will be disconnected. After the voltage returns to the set range, the load will automatically turn on.
The desired voltage value and switching delay time are set through the button.
Compact design, reliable operation, easy installation on a DIN rail.
Aluminum and copper wires can be used for connection.
Applicable in administrative, industrial and residential buildings; electrical panels and industrial machines, where it is important to ensure constant voltage and current monitoring.
Main functions:
1. Overvoltage protection.
2. Undervoltage protection.
3. Overcurrent protection.
4. Automatic recovery.
5. Voltage display (voltage measurement).
6. Current display (current measurement).
