The present disclosure relates to a frame of an electromagnetic contactor, and more specifically, to an electromagnetic contactor having excellent coupling force between an arc box and a frame. The electromagnetic contactor, comprises: a lower frame; an upper frame coupled to the upper portion of the lower frame; and an arc cover coupled to the upper portion of the upper frame, wherein a first coupling part is protrudingly formed on one surface of the lower frame, a second coupling part, connected to the first coupling part, is protrudingly formed on one surface of the upper frame, and a third coupling part, connected to the second coupling part, is protrudingly formed on one surface of the arc cover, wherein the fastening member is fastened by connecting the first coupling part, the second coupling part and the third coupling part.

Electromagnetic contactor

An arc box and an electromagnetic contactor comprising same are disclosed. The arc box according to an embodiment of the present disclosure comprises a coupling protrusion. The coupling protrusion is inserted into and coupled to a grid coupling hole of an arc chamber. Therefore, the arc chamber can be stably coupled to the arc box. In one embodiment, the coupling can be performed through snap fastening. Therefore, the arc chamber and the arc box can be easily coupled. A rib part is formed on the arc box. The rib part is positioned to be adjacent to the coupled arc chamber so as to prevent pitching of the arc chamber. Therefore, the arc chamber coupled to the arc box can stably maintain a stopping state.
