These Series switch mainly used for AC 50Hz, rated voltage up to 380V and below, DC voltage up to 220V, rated current to 160A electrical circuit for manually infrequent making or breaking the circuit for the purposes of control and conversion ,can also controlling three-phase asynchronous motors and circuit directly as the purposes of master control and measurement. The products widely used, instead of the various national switch, can be used as the circuit control switch, measuring equipment switches, motor control switches and the master control switch, and welding machine switch and so on. Compliance with standards: The changeover switch use to the main circuit switching and direct control comply with GB14048.3-2001 The changeover switch use to master control comply with GB14048.5-2001
