    Modularization of Functional Unit

    The main circuit unit and running product are coherent in interchangeability.

  • administration.icon02
    Strong Versatility

    The operating mechanism can be separated from the whole circuit breaker for convenient and easy maintenance and fix.

  • administration.icon02
    Low Maintenance

    No need of adjustment of driving unit; long-acting lubricating, reliable corrosion resistance, and high mechanical stability make low maintenance possible.

  • administration.icon02
    Long-acting Lubricating

    We apply German lubricating grease boasting lower starting torsion, stronger anti-aging and oxidation resistance.

  • administration.icon02
    Strong Corrosion Resistance

    Utilizing zinc-nickel alloy plating line with a German process to make sure our corrosion resistance is 5 to 7 times stronger than ordinary zinc-plating process.

  • administration.icon02
    Strong Expandability

    This product can easily realize diverse arrangements and combinations to meet functions like expandability and control.
