Scope of application

 The CJX2 series exchange contact device (hereafter refers to as contact device), mainly uses in to exchange 50Hz (or 60Hz), the voltage to 660V, the electric current to in the 95A electric circuit, puts through for the long-distance range and divides breaks the electric circuit, frequently the starting and using of the control motor, and may protect with the suitable thermal relay composition electromagnetism starter possibly occurs has operated the load electric circuit .
       This contact device series changes in French TE in Corporation LC1-D then becomes, definitely may substitute the import product

Type & Meaning

Normal working condition and installation condition

3.1 The surrounding air temperature is: In -5 ℃ ~ +40 ℃, 24 hours its mean value does not surpass +35 ℃;
3.2 Altitude above sea level: Does not surpass 2000m;
3.3 Atmospheric condition: In +40 ℃ space and times was mad the relative humidity does not surpass 50%, in compares under the low temperature to be allowed to have a higher relative humidity, the wettest month monthly mean most low temperature does not surpass +25 ℃, this month monthly mean maximum relative humidity does not surpass 90%, and the consideration because the temperature change occurs on the product congeals the dew;
3.4pollution grade : 3 level;
3.5installation sort : Ⅲ level;
3.6 Installs the condition: The fitting surface is not bigger than with Vertical surface the gradient ±5°;
3.7 Impact vibration: The product should install and use in not remarkably undulates, the impact and the vibration place

Structure characteristic

5.1 May use the building block system to install the way to install the assistance contact group, air time delay (its time delay scope see Table 4), appendix and so on thermal relay, the group synthesizes the many kinds of derivations product: Timing contactor, reversible contact device, magnetic starter, star triangle starter.

5.3 The contact device has the volume slightly, the weight light, the power loss small, the life high, safe is reliable and so on the characteristic ,
5.4 The contact device main body and below has pair of open in 32A often to shut assists the contact, 40A and above has a pair of open and often shuts assists the contact, moreover may install the F4 assistance contact group (two group or four groups), its combination situation (see Table 5),
5.5 The contact device besides uses the bolt installment, but also may use 35mm (CJX2-09~32) and 75mm(CJX2-40~95)     the standard caliper gauge axle installs.
