6 . Structure Features The contactor is composed of arcextinguishing system, contact system, base frame and magnetic system (including iron core, coil) The contact system of the contactor is of direct action type and doublebreaking points allocation. The lower baseframe of the contactor is made of shaped aluminum alloy and the coil is of plastic enclosed structure. The coil is assembled with the amarture to be an integrated one. They can be directly taken out from or inserted into the contactor. It is convenient for user's service and maintenance. Scheme of NC5~5 structure 3 : arcextinguishing system, : contact system, 3: base frame 4: magnetic system 4 NC series contactor is of short arcing distance. For example, the arcing distance of NC5~330 contactor is only 0mm (00~500V), which is about one sixth that of the previous contactor of same capacity. It is an excellent complementary element used for an electric control device and it occupies smaller space in a complete set of equipment. The mechanical interlock can be added to the contactor in both horizontal direction and vertical direction. Three sets of contactor can be interlocked in the vertical direction.
