Power switch 1) high quality with most competive price 2) certificares CE,CCC,ISO9001,etc 3) timely delivery
Power switch
It can in place of circuit breaker , protector , relay , contactor .
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%
Power switch (New design )
