Introduzione

3 phase 4 wire self resettable over and under voltage protector   When the power supply line has overvoltage and undervoltage, the protector can quickly and safely cut off the circuit under the continuous high-voltage impact to avoid the occurrence of accidents caused by abnormal voltage sent to the terminal electrical appliances, and when the voltage returns to normal values, the protector will automatically turn on the circuit within the specified time to ensure the normal operation of the terminal electrical appliances in the unattended situation.

Second, the main technical parameters

1. Rated current: 32A, 40A, 50A, 63A, 80A, 100A

2. Working voltage: AC230V (phase line to neutral line working mode)

3. Overvoltage protection value: AC270V ±5V

4. Undervoltage protection value: AC170V ±5V

5. Reset time after failure: 40 seconds ±5 seconds

6. Action time: 0.1 seconds

7. The products mainly have the functions of phase loss protection, lack zero line protection, sovratensione protection, under-voltage protection and so on
