Product Description

Application

SMGQ2 series of automatic transfer switch is mainly used for electric distribution network or motor network with rated voltage 380V. 50Hz, DC rated voltage 220V,rated current 16A to 3200A. change over between main power and backup power system .power grid and genset. Meanwhile it can be used as isolation of unfrequency making and breaking circuit

It is widely used in the transmission and distribution system and automation system of the important place which not allow power cutoff such as fire-fighting.Hospital, Bank, high building etc.The SMGQ2 series automatic tranfer switches comply with the following standards
