Descriptions: multi-function protective device is designed to measure single phase two wire AC active energy and used in overvoltage protection, under voltage protection and over-current protection. case of over-voltage fault, under-voltage fault or over-current fault in line, this product can instantly power off the load to prevent electrical equipment from being burnt. over-voltage, under-voltage and over-current values of this product can all be set up by yourself and can be adjusted on the basis of local practical is a long use-life product with the advantage of high stability, high over load capability, low power loss and wide working voltage range.
Features: display with backlight, can display total active energy (kWh), real time current (A), voltage(V), active power (W). display kWh (4 digital+1 decimal) , Bi-directional total active energy measurement, reverse active energy measure in the total active energy. self-design has function of lighting protection. protection, under voltage protection and over-current protection can select auto-Reclosing mode or manual--Reclosing mode. case of over-voltage fault, under-voltage fault or over current fault in single phase line, the product can power off the line and can automatically restore. connecting the line over a time delay after voltage of the lien is recovered to normal condition. case of transient over voltage in line, the product can protect the equipment from false operation. case that the line subjects to unstable voltage or sudden power-off and power-on due to loosened connection and other fault, the product will disconnect the line. fault voltage of the line reaches the peak, the product itself will not be damaged. over-current protection mode , you also can select Malignant load protection (Pure Resistive Load limit) which is used for Apartments and Student Dormitories electric safety. can select the circuit output cycle switch on/off mode. indication of overvoltage protection, under voltage protection and over-current protection. design for the protection , you can closed t any one of overvoltage protection, under voltage protection and over-current protection in any time.

Notes: input and output shall be corrected connected on the basis of the product marking. (Where in, the load current shall be less than protective current of the product. ) line N cannot be improperly connected and shall be reliably wired; otherwise, the protector may not work normally. powering on, please carefully check whether the wiring is correct, whether the load matches with protective current of the product and whether the binding screw is tightened; otherwise, the product may be damaged. powering on the product, dont touch any live part to avoid electric shock. product shall be combined with micro circuit breaker to play a role of short-circuit protection; otherwise, the product may not be able to realize load limit protection in case that input or load end of the product appears short circuit. the product has automatic reset function, after the product plays the role of protection and acts, it is necessary to remove the load (electric appliance) and check the circuit; otherwise the product will be frequently connected and disconnected to the load. Finally, the product or its circuit may be burnt due to frequent overload connection and disconnection for long time
