Feature | Specification | Function description |
Power-on delay time | 1s-500s | After external power cut,the time needed for power-on when power recovery. |
Over-voltage protection value | 230V-300V | When the voltage is higher than the set value, the protector will cut off the line. |
Over-voltage recovery value | 225V-295V | When the voltage is lower than the set value, the protector will automatically reset,and the set value must be less than the over-voltage protection value by more than 5V. |
Over-voltage recovery delay time | 1s-500s | After voltage recovery,the time needed for automatic reset. |
Over-voltage protection action time | 0.1s-30s | When the voltage is higher than the set value,the time needed for protection action. |
Under-voltage protection value | 140V-210V | When the voltage is lower the set value,the protector will cut off the line. |
Under-voltage recovery delay time | 1s-500s | After voltage recovery,the time needed for automatic reset. |
Under-voltage protection action time | 0.1s-30s | When the voltage is lower than the set value,the time needed for protection action. |
Three phase voltage error value | -9.5%-9.5% | Correct the three phase voltage error. |
Three phase voltage unbalance value | 20V-99V | When the error among the three phase voltage is bigger than the set value,the protector will cut off the line. |
Three phase voltage unbalance recovery value | 15V-94V | When three phase voltage unbalance value is lower than the set value,the protector will automatically reset. |
Phase sequence protection switch | OFF/ON | Switch on or on the phase sequence protection function. |
Over-current protection value | 3A-63A-OFF 3A-100A-OFF | When the current is higher than the set value, the protector will cut off the line. |
