The contactor is composed of arc-extinguishing system, contact system, base frame and magnet system (including iron core, coil) The contact

system of the contactor is of direct action type and double-breaking points allocation. The lower base-frame 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.

1: arc-extinguishing system, 2: contact system, 3: base frame 4: magnetic system

NC2 series contactor is of short arcing distance. For example, the arcing distance of NC2-115~330 contactor is only 10mm (200~500V), 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.

Connection of connection plate

4.1 Refer to fig below for connection mode of connection plate,

the interlocked contactors could be mounted horizontally

or vertically. For vertical mounting, contactors with lower

current mounted at the upper position.

4. Structure Features

4.2 For reversing type contactors assembled with

NC2-115~225 and NC2-265~630, which will be mounted

vertically, a padding plate should be added at the bottom

of NC2-115~225.
