Mainly used for home and similar use of low-voltage distribution lines, when the line over voltage or undervoltage failure can automatically disconnect, and can automatically detect the line voltage, when the line back to normal when the automatic closure.


 


Products with high-speed low-power processing as the core control, high load capacity magnetic holding relay for the main control circuit, with online production voltage LED digital display, indicator light status indication, the product can be sustained under high pressure shock.


 


Timely protection of the safe use of load appliances. Product protection action when the neutral line is not open, in the installation should be consistent with GB16895.21 and other relevant installation procedures.
