| Warrenty | 2 Years |
| Technical parameter | setting range | Factory setting | Step | Function description |
| Power-on delay time | 1S-500S | 10S | 1S | After external power cut,the time needed for power-on when power recovery. |
| Over-voltage protection value | 230V-300V | 270V | 1V | When the voltage of one phase is over the set value,the protector will cut off this phase and switch to the next phase according to the sequence set in Pr1.When all three phases’voltage is over the set value,the protector will cut off all lines |
| Over-voltage recovery value | 225V-295V | 265V | / | When the voltage is 5V or more than 5V lower than the over-voltage protection value,the protector will automatically reset.This parameter automatically changes with the change of over-voltage protection value and does not need to be set. |
| Under-voltage protection value | 140V-210V | 170V | 1V | When the voltage of one phase is under the set value,the protector will cut off this phase and switch to the next phase according to the sequence set in Pr1.When all three phases’voltage is under the set value,the protector will cut offall lines |
| Under-voltage recovery value | 145V-215V | 175V | / | When the voltage is 5V or more than 5V higher than the under-voltage protection value,the protector will automatically reset.This parameter automatically changes with the change of over-voltage protection value and does not need to be set. |
| Over-current protection value | 3A-63A-OFF 3A-100A-OFF |
40A 60A |
1A | When the current is higher than the set value,the protector will cut off the line.When setting OFF,the protector will turn off over-current protection function. |
| Times of continuous over current protection |
OFF-1-20 | OFF | 1 | 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 sequence switching detection time |
OFF-1S-500S | 10S | 1S | The time required to detect whether the voltage of the priority phase is stable before disconnect. OFF means that there is no need to wait for detection and switch directly to the priority phase. |
| Phase sequence recovery switching settings |
ON | ON-OFF | / | ON means that when the priority phase returns to normal,it will switch to the priority phase. OFF means that even if the priority phase returns to normal,the protector will not switch to that phase. |
| Phase sequence switching recovery time |
OFF-1S-500S | 10S | 1S | Time required to switch to priority phase. |
| Over-current protection action time |
0.1S-30S | 1.0S | 0.1S | When over current,the time needed for protection action. |
| Voltage calibration | -9.5%-9.5% | 0 | 0.5 | Correct the voltage error. |
| Current calibration | -9.5%-9.5% | 0 | 0.5 | Correct the current error. |
| Input phase priority selection | ABC-ACB- BAC-BCA- CAB-CBA |
ABC | / | Set theinput priority of each phase. A:L1,B:L2,C:L3 |
