    Why Choose Us?

    Product action reliability design

    Product Highlights:

    Reliable pull-in at 70%~110%Us, carrying line voltage fluctuation;

    The influence of voltage fluctuation:

    Considering line voltage fluctuation is an inevitable phenomenon in most application scenarios, short-term pressure loss will cause the contactor to malfunction and affect the operation of the equipment; Frequent pressure loss will cause frequent contactor release, affecting product life and equipment life.

    Method to realize:

    Matching calculation of suction force and reaction force curve to ensure reliable suction.

    Product Highlights:

    Reasonable iron core and magnetic split ring, no vibration after 75% Us is attracted;

    The influence of vibration:

    Affect product life and temperature rise;

    Method to realize:

    Through the optimized design of the short-circuit ring to ensure sufficient retention.

    Design of Product Reliability

    Product Highlight:

    Coil protective cover design to better protect the iron core;

    Damage of Unprotected:

    Most of the application scenarios are dusty and the iron core is not protected, which will cause the iron core area to be gray, then affect the product performance;

    Product Advantage:

    Silver contact point protection treatment ensures long-term low contact resistance and connection reliability;

    Influence of Unprotected:

    Silver contact point are easy to vulcanize, which affects product contact resistance; no power after action;

    Method to realize:

    Increasing the cleaning of silver contact point and the high-temperature protection treatment process, extending the vulcanization cycle of silver contact point to make the contact resistance change slowly;

    Product Advantage:

    AgCdO2 silver contact point, and the uniform thickness of the silver layer ensure the electrical life;

    Design of Product Practicality

    Product Highlight:

    Full series of standard quick-connect terminals; In addition to the quick-connect terminal, there are two options for Screw connection method, and being arbitrarily matched;

    Product Highlight:

    The bottom plate is installed with a porous design, and the installation size can be freely selected;  Product Highlight:

    3P&4P accessory auxiliary contact point has multiple combinations choice , and there are micro switch types to ensure low current reliability;
