CB class moulded case dual transfer switch automatic switch with GB/T 14048.11 standard
FTSM series automatic transfer switch are mainly composed of power conversion actuator, circuit breaker and controller. It is able to actuate the automatic transfer between the normal power and reserve power, requiring no manual operation. This switch conforms to the clauses stipulated in the GB/T14048.11 Automatic transfer switching equipment. It is operating mechanism has reliable electric and mechanical interlock to prevent the normal power and reserve power being switched on at the same time.
