1 use and scope of application
1.1 CJ40 series AC contactor (referred to as contactor) for AC 50Hz, rated voltage to 660V, current to 1 000A power system connected to the circuit and with the appropriate thermal relay or electronic protection device into a motor starting To protect the circuit from which overload may occur.
Contactor according to GB14048.4 and JB8591.3 design, manufacture and testing.
1.2 normal working conditions and installation conditions
1.2.1 ambient air temperature: the upper limit of +40 ℃, 24h its average does not exceed +35 ℃; the lower limit of -5 ℃.
 1.2.2 Altitude: The altitude of the installation site does not exceed 2 000 m.
 1.2.3 Atmospheric conditions: The relative humidity of the air at the installation site is not more than 50% at a maximum temperature of + 40 ° C; a higher relative humidity is allowed at a lower temperature; the minimum minimum temperature at the wettest month does not exceed + 25 ° C When the monthly average maximum relative humidity of the month does not exceed 90%, and should be considered due to temperature changes occurred in the product surface condensation.
1.2.4 pollution level: pollution level of 3.
1.2.5 Installation category (overvoltage category): The installation category is III.
 1.2.6 Installation conditions: the installation surface and the vertical tilt of not more than 5 °.
Note: The composition of the mine starter products and the vertical surface of the tilt is not greater than 15 °, when ordering to the manufacturer to declare.
2 model meaning  
Auxiliary specification code consists of four parts, according to the need to select the following order *
  Use, where:
  A) the first part of the main circuit with a number of bits that number, respectively, with 3,4, said 3 pole, 4 pole but 3 can not write;
  C) the third part of the rated power supply voltage, with the letter "AC" that the exchange, the first part of the rated power supply voltage, the use of the letter "AC" "DC" that DC, after the letter with the rated power supply voltage value, but "AC380" can not write;
  D) The fourth part uses the letter "F" and 2 digits to indicate the type and number of auxiliary contacts, the previous digit indicates the number of the auxiliary contact contacts, and the latter digit indicates the number of auxiliary auxiliary contacts, F42 "can not write, 40A the following specifications of the contactor only four pairs of contacts," F22 "can not write.
3 Dimensions and mounting dimensions
The dimensions and mounting dimensions of the contactor are shown in Figures 1 and 1.
.4 contactor withstand the ability of overload current:
The contactor can carry 8 times the overload current of AC-3 maximum rated operating current, the energization time is 10s. 5 control circuit working conditions
5.1 control coil for the exchange of 50Hz, rated voltage Us 36V, 127V, 220V, 380V, other specifications can be negotiated with the manufacturer.
5.2 Control power supply voltage range of 85% to 110% Us. 6 installation and precautions
6.1 The following should be noted before installing the contactor:
A) Check the contactor to confirm that the parts are not damaged and have good performance.
B) Check that the contactor nameplate and coil label correspond to the normal operating conditions used.
6.2 contactor installation should pay attention to:
A) Installed according to the specified working position;
B) Check the terminal mark: Main circuit: 1 / L1, 3 / L2, 5 / L3 is the incoming terminal, 2 / T1, 4 / T2, 6 / T3 is the outgoing terminal; auxiliary circuit: 13,23,33,43 ... ... moving out of the line for the 14,24,34,44 ... ... moving into the line for the 11,21,31,41 ... ... moving out of the line for the 12,22,32,42 ... ... control Circuit: Terminals A1, A2; c) The metal base of the contactor is provided with a grounding screw and has a clear grounding mark. The contactor should be used to ensure that the contact surface of the grounding screw is good and the grounding is reliable. Green color line.
6.3 The main circuit of the contactor allows the maximum cross-section of the access wire to be seen
7, use and maintenance
7.1 contactor factory, overtravel, distance and other parameters have been adjusted, so the user can directly use, not allowed to adjust.
7.2 contactor in the operation should be regularly checked, check the cycle depending on the working conditions of the decision, check the power should be cut off, check the items are as follows:
     A) remove fouling, especially in and out of the line and the core of the pole;
B) cleaning the metal particles on the surface of the contact;
C) tighten all fasteners;
D) Remove the carbides and metal particles from the arc extinguishing cover.

The same time as
CJ40 series AC contactor (hereinafter referred to as contactor) for AC 50Hz, rated voltage to 660V, current to 1000A power system connected to the circuit and with the appropriate thermal relay or electronic protection device into a motor starter To protect the circuit from which overload may occur.
Contactor according to GB14048.4 and JB8591.3 design, and manufacturing inspection.
