The automatic transfer switch is composed of one or more switching devices for automatically disconnecting the load circuit from one power supply and connecting it to another electrical appliance. To be designed in strict accordance with national standards, NDQ series of automatic transfer switches are applicable to the power distribution system with the rated voltage of AC400V(50Hz/60Hz), which are widely used in construction, industrial control, telecommunication, power and other fields over the years, with the reliability and stability recognized by many customers.
◆ CB-gradeproducts adopt our molded case and miniature circuit breakers as actuators with a high breaking capacity.
◆ PC-gradeproducts adopt our variant disconnecting switches of the miniature circuit breaker as actuators with simple but reliable structure.
◆ Using the PIC single chip as the control core, the intelligent controller is powerful and easy to expand with the strong anti-interference ability.
◆ Reliable mechanical interlocking device and electric interlocking protection are provided between mechanisms so as to prevent the occurrence of simultaneous closing.
NDQ series of automatic transfer switch has obtained China Compulsory Certification (CCC) for products and CE certification.
