Why one of the main products electric apparatus Co., Ltd. the people CJ40-125 in Shanghai exchange the contactor, it is the fairy of Leqing.
Why main product, Co., Ltd. of electric apparatus, it will be the intersection of Leqing and the intersection of city and fairy: Snide, Siemens, LS produces the electricity, ABB, Changshu switch, the people in Shanghai, Omron, Mitsubishi, Japanese Fuji, the electromechanics of intellectual circles, the platform is fitted etc..Cooperate with a plurality of producers, sells directly to households in the producer, the selling idea which the producer retails that the real one has made sure the producer sells in batches,Have brought the direct purchase profit to the masses of customers, purchase the costly problem after solving every large complete set of producers, supplying all parts of the country in production in our company, welcome old and new customers to consult!

Applicable scope
--------
1,This Standard is suitable for
--------------
Series CJ20 exchange the contactor (hereafter referred to as the contactor) . This contactor is used mainly for exchanging 50Hz, specified voltage to 660V (specific grade to 1140V) ,Put through and divides and break the circuit in the power system to 630A of the electric current, and make up the electromagnetic starter with the appropriate hot relay or electron type protector, the circuit of year may happen in order to protect. Accord with the Ministry of Machine-Building Industry standard JB2455-85 " low-voltage contactor " with other standard relation this Standards, and adopt IEC158-1(1970) equivalently , IEC158-1A(1975) , IEC158-1B(1979) , IEC158-1C(1982)<>.
2, basic parameters
------------
2.1 The insulating voltage of amount of the contactor, the working voltage of amount, agree to generate heat in the electric current, power that and work in electric current sum amount and work in corresponding work system, corresponding amount that uses under the classification
2.2 Specified work system The contactor is suitable for the following work systems:
2.2.1 Eight-hour day: This work system is a basic work system, the agreement of the contactor generates heat in the electric current Ith namely therefore the work system is confirmed.
2.2.2 Incessant work system: Mainly touching the head in order to contact of this work system keeps closing, and year exceed 8h (several weeks, several months even a few years) with a stability electric current Do not divide and break either.
2.2.3 The work system of intermittent cycle: The intersection of contactor and load under work system this 0.4 in factor, until might realize in the every hour operate rank number of times divide at most:
CJ20-10- CJ20-160 1200 grades (namely 1200 times / hour) ;
CJ20-250- CJ20-630 600 grades (namely 600 times / hour) .
3,The air is electromagnetic type to exchange the contactor CJ40
--------------------------------
1,CJ40 exchanges the contactor and kills arcly and covers and replaces the traditional vertical sewing type of potter's clay to kill the arc cover with one stretch of types of plastic bar, exist potter's clay kill arc to put on fragile shortcoming, and because plastic the intersection of bar and a superior one put out arc performance, make it shorten greatly not to fire arc time, raise and divide into and break ability notably. The whole series are divided from 63A to 1000A into four basic frames and 13 pieces of electric current specification, namely 125 frames (63A, 50A, 100A, 125A) together , 250 frame( 160A, 200A, 250A) , 500 frame( 315A, 400A, 500A) , 1000 frame( 630A, 800A, 1000A) ,Among them 1000 frames and three specification products have been accomplished zero the arc requirement has flown, CJ40 exchanges the contactor and to no small extent shrinks than the volume that series CJ20 with the capacity exchange the contactor; 125,250,500 three ten electric current of frame design four product very much specially in the specification. For the situation in need of making and breaking the centre line at the same time in the three-phase Line four electric power system to select for use. The intersection of amount and for 380V, 660V, the intersection of 1140V and pairs of broken some structure of moving etc. direct working voltage.
2,The above is about two sections of commonly used air are electromagnetic type exchanges the contactor: The concrete introductions of CJ20 and CJ40, has good instructing results to generally selecting type, combine one's own experience at the same time, it is necessary to be very much.
