A Terminal type

It is dominated by the utility power type ,suitble for the two - circuit utility -power main and reserve power system.

When the main power circuit has the phase failure or voltage loss ,the switch can automatically input into the reserve power cicuit ; when the main power circuit recovers to the normal state ,the switch can automatically input into the main power circuit .

B General type 

It is dominated by the utility power type ,suitble for the two - circuit utility -power main and reserve power system.

 When the main power circuit has the phase failure or voltage loss , under voltage and phase failure ,the switch can automatically input into the reserve power cicuit(adjustable time delay ) ;when the main power circuit recovers to the normal state ,the switch can automatically input into the main power circuit (adjustable time delay ). The controller has the self -input  non-self -reset  and mutual -standby for setting .
