    Type and meaning

    jkldryf

    Type and meaning

    The auxiliary code is composed of 5 parts, which are selected in the following order as needed:
    • In the first part, “y” means general type, “N” (can be omitted) means reversible type;
    • In the second part, l digit is used to indicate the number of poles of the main circuit: 3 and 4 respectively indicate 3 and 4 poles, and 3 can be omitted;
    • In the third part, 2 digits are used to indicate the highest rated working voltage, "06" (which can be omitted) indicates 690V, "11" indicates 1140V;
    • The fourth part indicates the rated control power supply voltage, with letters "Ac" indicating alternating current 50 Hz and "Dc" indicating direct current. The value of the rated control power supply voltage is behind the letters, but “AC380” can be omitted;
    • In the fifth part, the letter "□" and two digits are used together to indicate the type and number of auxiliary contacts, of which the first digit indicates the number of pairs of normally open auxiliary contacts and the second digit indicates the number of pairs of normally closed auxiliary contacts, but “□42” can be omitted.
    Note: This item includes two parts, i.e., the number of main contacts and the number of auxiliary contact, which are indicated by number respectively, as shown in the diagram below. ( -□□-□□ ) indicates: - number of normally open main contacts, number of normally closed main contacts - number of normally open auxiliary contacts, number of normally closed auxiliary contacts.

    Normal working conditions and installation conditions

    • The altitude of the installation site should not exceed 2000m;
    • The ambient air temperature should not be higher than +40℃ and not be lower than -5℃;
    • When the highest temperature is +40℃, the relative humidity of the air on the installation site should not be higher than 50%; A higher relative humidity is allowed at a lower temperature; In the wettest month, the monthly average minimum temperature should not exceed +20℃, and the average maximum relative humidity should not exceed 90%. Measures should be taken for condensation on the product due to temperature change;
    • The inclination between the installation surface and the vertical plane should not exceed ±5°.
    • Pollution level: level 3;
    • The product should be installed in a place without obvious shaking, impact and vibration.

    Structural features of the product

    CJ40-63~1000 AC contactor adopts the structure of oven type, normal installation, direct acting and double breakpoints. The auxiliary contacts are installed on both sides of the main contact as independent components, which are electrically separated; The iron core is a U-shaped structure with the permanent air gap. The base is made of aluminum alloy die-casting (for CJ40-630A and above), which is installed by screws: But. The base of CJ40-63~125 is made of unsaturated polyester glass fiber reinforced molding compound, which may be installed by screws or by “TH75” guide rail. With the advantages of high breaking capacity and high reliability, etc., the arc extinguishing chamber is made of arc resistant plastic and iron grid.
