Giriş

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. Aşırı gerilim koruma değeri: AC270V ±5V

4. Düşük gerilim koruma değeri: AC170V ±5V

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

6. Eylem süresi: 0,1 saniye

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