ABSTRACT:It is the main products of low-voltage electric apparatus , and the basic component to exchange the contactor , have a large capacity and a wide range. The improvement of its advanced life-span of structure and dependability , has already influenced the competitive power which enterprises produce, influence national economic construction again。CJ20 type exchanges the contactor and is used for exchanging 50Hz mainly (60Hz), the specified voltage is to 660V (whether specific grade can to 1140V), electric current for frequently putting through and assigning to and give up the circuit to the electric circuit of 630A and frequently start and control and exchange the motor remotely, suitable for making up the electromagnetic starter with the hot relay or the electronic protector , in order to protect circuit or exchange whom motor might take place pass loading and broken looks. CJ20-63 exchanges the contactor for the moving directly type, pair is a bit more broken, fix up three-dimensionally , of simple structure and compact, appearance install of size old product dwindle greatly. 目 录 摘 要
