    Product Series


  • industrial power distribution

  • Underpressure tripper;auxiliary contact;Alarm contacts;shunt release;Electric operating mechanism, manual operating mechanism

  • *Small size and compact structure;

    * 4 kinds of shell frame grades, 5 kinds of breaking capacity, can meet the application in various fields of industry and power distribution;

     *5 kinds of intelligent controllers, 4-stage protection, monitoring and protection of various circuit parameters, signal contact input and output, self-diagnosis and fault memory, communication functions;

    * The DOUBLE-speed contact design effectively protects the main contact; 12 contacts are connected in parallel, and the electric repulsion is reduced to 1/12; the electric repulsion is compensated for the contact pressure, which improves the dynamic and thermal stability, thereby increasing the electrical and mechanical life.
