| Code | Technical Parameter | Minimum Protection Value | Maxmum Protection Value | Default Protection Value | Function Description |
| P1 | Power-on delay time | 1s | 500s | 10s | After external power cut,the time needed for power-on when power recovery. |
| U1 | Over-voltage protection value | 230V | 300V | 270V | When the voltage is higher than the set value, the protector will cut off the line. |
| U2 | Over-voltage recovery value | 225V | 295V | 265V | When the voltage is lower than the set value, the protector will automatically reset. |
| U3 | Over-voltage recovery delay time | 1s | 500s | 30s | After voltage recovery,the time needed for automatic reset. |
| U4 | Over-voltage protection action time | 0.1s | 30s | 1.0s | When the voltage is higher than the set value,the time needed for protection action. |
| U5 | Under-voltage protection value | 140V | 210V | 170V | When the voltage is lower the set value, the protector will cut off the line. |
| U6 | Under-voltage recovery value | 145V | 215V | 175V | When the voltage is higher than the set value, the protector will automatically reset. |
| U7 | Under-voltage recovery delay time | 1s | 500s | 30s | After voltage recovery,the time needed for automatic reset. |
| U8 | Under-voltage protection action time | 0.1s | 30s | 1.0s | When the voltage is lower than the set value,the time needed for protection action. |
| U9 | Three phase voltage error value | -9.50% | 9.50% | 0 | Correct the three phase voltage error. |
| U10 | Three phase voltage unbalance protection value | 20V | 99V | 20V | When three phase voltage unbalance value is higher than the set value, the protector will cut off the line. |
| U11 | Three phase voltage unbalance recovery value | 15V | 94V | 20V | When three phase voltage unbalance value is lower than the set value, the protector will automatically reset. |
| U12 | Phase sequence protection switch | OFF | ON | ON | Switch on or off the phase sequence protection function. |
| C1 | Over-current protection value | 1A | 100A | 30A | When the current is higher than the set value, the protector will cut off the line. |
| C2 | Over-current recovery delay time | 1s | 500s | 30s | After current recovery,the time needed for automatic reset. |
| C3 | Over-current protection action time | 0.1s | 30s | 1.0s | When the current is higher than the set value,the time needed for protection action. |
| C4 | Three phase current error value | -9.50% | 9.50% | 0 | Correct the three phase current error. |
| C5 | Times of continuous over current protection | 0 | 20 | OFF | When The times of continuous over-current protection exceeds the set value,the protector will cut off the line,then it needs to be opened manually. |
| Phase-loss protection | ON | One of the three-phase voltages is losing,the protector will cut off the line. |
