  • Applicable occasions should free from inflammables, explosives, corrosives and severe vibration

Note: Customized products beyond those standard services condition are available, please check with sales before ordering.


  • Highly reliable operating mechanisms thanks to a low number of components which are manufactured using production systems for large quantities
  • Extremely limited and simple maintenance
  • The electrical accessories can be installed or replaced easily and rapidly thanks to the cabling which is already prepared with its own plug-socket connectors
  • Protective covering over the opening and closing pushbuttons to be operated using a special tool
  • Superior breaking capacity: It can break the circuit quickly and reliably to ensure the safety of the power system.
  • Long electrical life: The vacuum interrupter has a long electrical life, reduces maintenance frequency and cost, and improves the reliability of the product
  • Strong insulation performance: The product has a high insulation level, strong anti-interference ability, and good arc extinguishing performance.
  • Wide application range: It is suitable for various fields and industries with different requirements.
  • No emission of gas in atmosphere, little maintenance required, no danger of fire, silent operation
