The dual- automatic transfer switch (ATS) is a newly developed miniature household transfer switch, is mainly used to test whether the main or reserve is normal.When the normal supply is abnormal, the reserve supply will start work immediately to continuity, reliability and safety of the supply. It is specially designed for household rail installation for PZ30 distribution box.The ATS is suitable for emergency supply systems of AC50 or 60Hz and rated voltage 400V. It is featured with firm structure, reliable transfer, easy installation and maintenance, and long life, is widely used in places where frequent outage is not allowed. Both electric and operation and manual operation are available. The ATS is composed of TES and controller.According to the standard GB or T1404811 Part 6-1: Multiple function equipment - Transfer switching equipment, we can know that ATS is the most suitable low-voltage switchgear and control device.Manual or automatic operation:Excessive silver alloy loss may occur during manual generation and down. Therefore, set the selector switch at the manual position under normal condition, and pull it to the manual position when all is turned off to check and maintain the operating system and contacts. After the manual operation is completed pull the selector back to the automatic position.Control circuit:ATS will be active in an . After the conversion is complete, the coils in the control circuit are disconnected by the internal converter. The coil can operate normally with a rated voltage of 80 percent -110 percent , and too low voltage may cause the coil to heat up or even ignite.Colour: WhiteMaterial: PlasticSize: 140x103mmPackage Contents:1 x transfer switchOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
