Abstract:
     It is a kind of contactor, composed of touch, electromagnetic and action devices as well as thermal and electromagnetic trip gears on each phase. Based on the requirements of possible condition, i.e. in addition to manual labour, it can be cut-in and broken-out at any further place, and it can guarantee the safety during overload and short circuit. Here it also suggests another structure, in which armature iron of electromagnet is acted upon the cut-in key, or it joins through a crank with a prolonged piece of the mutual bridge contact chip shelf of the touching device, there is still a sliding block. It can clamp not only the crank, but also the thermal and electromagnetic trip gear.
