General
1)NDQ3B automatic transfer switching equipment (hereinafter referred to as ATSE) is made up of device body and intelligent automatic controller two parts.
2) The device body is made up of two circuit breakers (refer to the technical parameters for model and specification) that are equipped with electric operating mechanisms as well as accessories (auxiliary alarm contact and so on) mechanical interlocking mechanism, electrical interlock terminal block and so on, all the parts are installed on a metal plate.
3) Intelligent automatic controller is made up of novel singlechip as well as output and other modules.
4) The two parts are connected by aerial plug port and special shielded cable whose length is not over 2m formed into intelligent control system whose control supply voltage is 220V, 50/60Hz.
5) ATSE has function of mechanical and electrical dual interlocking protection, guarantees safe and reliable power supply.
6) It is able to finish automatic dual-power transfer in single-phase 220V system, three-phase three-wire system and three-phase four-wire system.
