Precautions
1.This product has no isolation function. Please disconnect the front stage when repairing the circuit breaker switch.
2.The zero line (N line) of this product is directly connected without disconnection function.
3.The protector must be wired according to the markings and must be connected correctly.
4.Although this product has limited current protection function, it cannot replace circuit breakers, please install circuit breakers such as DZ47 or C65 at the front or the end of the line for short circuit protection.
5.Before use, please tighten the clamp screw to avoid product damaged caught by poor connection.

Function Parameter Tables
| Function | Set Parameter Range | Factory Default Settings | Function Description |
| Power Restoration Delay Protection | ----(Hand Movement) 0000-9999Second(s) | 5S | This function is to protect the device being destroyed by instantaneous high voltage and surge during power restoration. |
| Over Voltage Limit | 60-300V | 275V | If the over voltage limit is set at 300V, when the voltage is over 300V, the device will automatically switch off. (Every phase can be set separately) |
| Under Voltage Limit | 60-300V | 175V | If the under voltage limit is set at 60V, when the voltage is under 60V, the device will automatically switch off. (Every phase can be set separately) |
| Under Voltage and Over Voltage Protection Delay | ----(Hand Movement) 0000-9999Second(s) | 20S | If the voltage is over or under the set value, the device will automatically switch off and when the voltage returns to normal value it will recover after the set delay time. |
| Under Current Limit | 0.0-60A | 0.0A | If the under current limit is set at 60A, the device will automatically switch off when the current is under 60A after the set delay time. (Every phase can be set separately) |
| Function | Set Parameter Range | Factory Default Settings | Function Description |
| Under Current Limit Delay Protection | 0000-9999Second(S) | 5S | When the current is under the setting value, the device will automatically switch off after the delay time. |
| Under Current Limit Protection Delay | 0000-9999Second(S) | 20S | When the current recovers to be over the setting value, the device will automatically switch on after the delay time. |
| Over Current Limit | 0.1-80A | 80A | If the over current limit is set at 80A, the device will automatically switch off when the current is over 80A after the set delay time. (Every phase can be set separately) |
| Over Current Limit Delay Protection | 0000-9999Second(S) | 5S | When the current is over the setting value, the device will automatically switch off after the delay time. |
| Over Current Limit Protection Delay | 0000-9999Second(S) | 60S | When the current recover to be under the setting value, the device will automatically switch on after the delay time. |
| Function | Set Parameter Range | Factory Default Settings | Function Description |
| Uneven Voltage Balance Protection % | On/off 000-9999% | On | The device will switch off if the highest or lowest voltage of ABC Phase exceed the set value. |
| Current Unevenness Balance Protection % | On/off 0000-9999% | On | The device will switch off if the highest or lowest current of ABC Phase exceed the set value. |
| Phase Sequence Protection | On/off | On | The device will switch off if there is any Phase error in the ABC phase sequence. |
