Feature

Main Circuit

  • The product features an integrated frame structure that ensures insulation while providing sufficient mechanical strength. The insulation withstands voltage levels up to 3kV.
  • The vacuum switch tube uses products from well-known domestic manufacturers with mature technology, reliable quality, and a good market reputation.
  • The conductive busbar is designed to be aesthetically pleasing and durable, with two center distance options available to accommodate different user needs.


Electromagnetic System

  • Utilizes a novel, fully sealed auxiliary switch, significantly improving the reliability and safety of the auxiliary switch.
  • The optimized action structure reduces the coil's starting and holding power, thus lowering temperature rise, extending lifespan, and enhancing reliability.
  • The actuator head of the auxiliary switch also employs buffering to reduce the impact force, thereby increasing the reliability of the auxiliary switch.


Action Structure

  • The pivot support is designed to be flexible, with no sticking and minimal axial play, improving performance and consistency.
  • A reasonable action mechanism ensures the coaxial movement of the vacuum tube's moving conductive rod, enhancing the performance and reliability of the contactor. The three-phase synchronicity and bounce characteristics are superior to similar products on the market.
  • Enhanced contact pressure in the main contacts improves electrical performance and operational characteristics, surpassing similar products.

Ease of Use and Maintenance

  • The control circuit and auxiliary contacts are connected to wiring terminals, and each terminal is clearly marked with its function to avoid incorrect wiring, making it user-friendly and easy to maintain.
Normal Operating Conditions


  • Ambient Temperature: The highest surrounding air temperature should not exceed +40°C, and the 24-hour average should not exceed +35°C, with a minimum not lower than -15°C.
  • Altitude: The installation site's altitude should not exceed 2000 meters.
  • Relative Humidity: The relative humidity of the atmosphere should not exceed 50% when the surrounding air temperature is +40°C.
  • Working Environment: There should be no exposure to rain, snow, open flames, explosive hazards, chemical corrosion, or intense vibrations.
  • Installation Conditions: The installation surface should not be tilted more than 5 degrees from the horizontal or vertical plane.
  • Pollution Level: Level III.
