 Overview

ZFK  composite  switch is a new generation of AC contactor .

1) using microcomputor control silicon devices connected to the circuit at zero voltage , zero-voltage time-division off the circuit , using electric shock load .

2) all the working process of the power grid without the impact of their loss is very low , the corresponding time is less than 20ms m

3) particularly applicable compensation capacitor in the dynamic switching  can also be used for motor starting control and resistive load switching , do  not need to install radiator

CONDITIONS OF USE

1 , altitude no more than 2500 meter

2 , ambient temperature -20C~+70C

3 , the air temperature 40C , less than 90%

4 , the surrounding evenronment without corrosive gas , no conductive dust , there is no flammable and explosive materials

5 , the hole voltage  range: rated voltage +20% or-20%
