General structure for SQ3M 3P 160A Terminal type automatic transfer switch

A: SQ3M Series automatic transfer switch is used for two circuit power system of AC 50HZ, rated voltage up to 690V.
B: It is able to actuate the automatic transfer between the normal power and reserve power, no need manual operation. Its operating mechanism has reliable electric and mechanical interlock to prevent the normal power and reserve power being switch on at the same time
C: Within the schedule time after the voltage of normal power detected failure, the switch can make the load connect to the reserve power from the normal power. After the normal power is recovered, the load returns to the normal power state again.
E: The switch has the phase-failure protection function, and comply to GB/T14048 standard
F: Three stable working states: Normal power on, reserve power offi; normal power off, reserve power on; normal power off, reserve power off.
G: The operating handle of switch is used for manual switching operation in the emergency state (used under the power failure)
