SATSG(WATSG) series automatic transfer switch
General
The automatic transfer switch equipment is a distributing unit composed of transfer switch equipment and control equipment. It is mainly used for monitoring the power circuit, when the normal power has the trouble, it can transfer the normal power to the reserve power, so as to finish the conversion of dual-power system.
At present, the automatic transfer switch equipment is used for the important power utilization locations, for example, class 1 and class 2 important loads, fire load, emergency lightings of the buildings ss well as the infrastructure .
SATSG series automatic transfer switch equipment (ATSE), Schneider Electric (China ) Investment Co., LTD./Schneider Wangao Electric Equipment Co., LTD.has PC level ATSE product is widely used for AC 50Hz distribution system of power supply transfer with load , with voltage of 380V and more and rated current from 32A to 800A. In addition ,it can be used to to infrequently make and break circuit and isolate circuit .
SATSG series automatic transfer switch equipment has the making capacity , bearing current capacity , power transfer capacity in the full load and ultra-strong interference resistance . It possesses three stable working positions , multi flexible control functions and characteristics of saving energy , reliable operation , no noise and so on .
