Basic Type:Mainstandby power,self-cast,self reset. Type 1 ,100A below , city power-city power ,self-cast,self reset ,two way power three phase short phase testing . Above 125A ,city power-city power ,main and standby or mutual power can do selection, Self-cast ,two way power three phase checking. Type II :city power-city power,main and standby or mutual power supply can do selection (that is self -casting self reset or self -casting without self reset) ,two way power three phase And lack phase,overload voltage checking . Type III:city power-Oil machine ,self casting self reset ,two way power supply three phase and lack phase ,overload voltage ,oil machine frequency testing .Basic type switch control characteristic Suitable for the two way main and standby power system ,self casting and self rest . It can expand function by outer connection. Type I switch control characteristic: 100A below: A :Suitable for two way main and standby power system; B:It will switch on to standby power supply circuit after switch delay( setting range 1-16S) When the main power supply circuit short circuit and loop(switch off or short phase).
