    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: 1 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 letter indicating alternating current 50Hz and "DC” indicating direct. The value of the rated control power supply voltage is behind the letters, but “AC380” can be omitted;
    • In the fifth part: the letter "g" 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 contacts, 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
    CJS0t-63~1000 AC contactor adopts the structure of open 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 CJS0t-6304 and above), which is installed by screws; But, the base of CJS0t-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.

    Frequently Asked Questions (FAQ)
    Can the AC contactors be customized for specific scenarios?
    Yes, all products of the company can be customized for production according to the user's specific usage scenarios.
    What are the ambient temperature and altitude limits for installation?
    The altitude of the installation site should not exceed 2000m. The ambient air temperature should be kept between -5℃ and +40℃.
    How does humidity affect the working conditions of the contactor?
    At a maximum temperature of +40℃, relative humidity should not exceed 50%. Higher relative humidity is allowed at lower temperatures (e.g., up to 90% average maximum relative humidity in the wettest month at an average minimum temperature of +20℃). Measures must be taken to prevent condensation caused by temperature changes.
    What are the structural features of CJS0t-63~1000 AC contactors?
    These contactors adopt an open-type, normal installation, direct acting, and double breakpoint structure. The auxiliary contacts are electrically separated and installed on both sides of the main contact as independent components. The U-shaped iron core features a permanent air gap, and the base is made of aluminum alloy die-casting (for CJS0t-6304 and above) or unsaturated polyester glass fiber reinforced molding compound (for CJS0t-63~125).
    What mounting options are available for the CJS0t-63~125 models?
    The base of the CJS0t-63~125 models is made of unsaturated polyester glass fiber reinforced molding compound, which can be installed using screws or mounted directly on a “TH75” guide rail.
    What is the pollution level and vibration tolerance for these contactors?
    The product is designed for Pollution Level 3 and must be installed in locations free from obvious shaking, impact, and vibration.
