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.
