Applicable scope
FCQ1 series automatic transfer switch (A.T.S.) is applicable for AC emergency power supply system of 50Hz, rated voltage 380V below and rated current 100A and less than. Through remote electric control or emergency manual control, it can realize the transfer between normal power and reserve power or between two closing loads, is mainly used the important fields where don’t permit power failure such as the hospital, emporium, bank, chemical engineering, metallurgy, high-rise building, fire control, etc.. The product conforms to the standards of IEC60947-6-1，GB14048.3 and GB/T14048.11.
