gpn -凯发一触即发

an introduction to
gpn - gqz series with the double under-voltage protection function of miniature circuit breaker is designed for building into the head of the household switches have abnormal voltage protection function and the integration of development design under-voltage protection products，it has the inverse time instantaneous short circuit protection and overload protection, electrical isolation function completely，and the line voltage rise and fall protection to prevent excessive household appliances phenomenon of damage due to voltage fluctuation，and it can prevent the temporary power outage and appear misoperation，and breakdown voltage can be automatically restored after a delay after recovery。
the circuit breaker high breaking capacity, small volume, reliable in performance，is an ideal product to the householder switch in the construction field。applied to ac 50 hz，the rated voltage of 230 v system。when the voltage in excess of the prescribed scope，under voltage protection circuit breaker delay to cut off the fault voltage after 0.5 s，in the delay time，the fault disappear，delay reset back。start the time 3 min after cut off the fault voltage，it's time to，and voltage is back to normal，circuit breaker automatically through to restore power to run。
