Product Description

1. Application:
When the power supply line has overcurrent, overvoltage, or undervoltage, the protector can quickly and safely cut off the circuit under continuous high-voltage impact to avoid accidents caused by the abnormal voltage being sent to the terminal appliance. When the voltage returns to the normal value, the protector will Automatically connect the circuit within the specified time to ensure the normal operation of the terminal electrical appliances under unattended conditions.

3. Protecting parameter setup steps:
Push the SETUP button to enter the voltage setting mode, the screen will display as shown in Figure A. The voltage screen displays OU (overvoltage protection setting 230V~330V), and the current screen displays specific values. You can add and subtract values by pressing the up and down keys.
If you only need to set the overvoltage value, press the confirm button to complete the setting.
If you continue to set the undervoltage value, continue to press the setting button, the voltage screen will display UU (undervoltage protection setting 160V~210V), and the current screen will display the specific value. You can use the up and down keys to add or subtract values.
If you only need to set the over-voltage and under-voltage values, press the enter key to complete the setting.
If you set the over-voltage and under-voltage trip time, over-current protection, over-current trip time, fault recovery time, parameter settings, continue to press the SET button with the above operation, and set the required values in sequence (the character menu description is as follows)
TU voltage trip time setting 1 second ~ 300 seconds
OI overcurrent protection value setting 1A~40/63A
TI overcurrent trip time setting 1 second ~ 30 seconds
TUI failure recovery time setting 1 second ~ 300 seconds.
