• BDNF4004

  Application Field

  BDNF4004 is an air-break disconnect switch used primarily in high voltages, low current applications. It’s useful in a variety of electrical connections, including lighting circuits, safety systems, and HVAC systems. It is also commonly used in mining, construction, transformer stations, and other hazardous areas. It offers superior contact reliability, flexibility in connection types, and robust endurance.

  Working Principle

  In the BDNF4004 air-break disconnect switch, a gaseous air between two contacts is employed to break the electrical connection. This design not only yields superior safety, but also eliminates arcing to reduce maintenance costs. In addition, the overall structure is composed of materials such as aluminum alloy and stainless steel, making them more durable and reliable under the condition of outdoor use. The operating life of the BDNF4004 exceeds the industry standards, and is capable of up to 6,000 mechanical operations and 600 electrical operations per hour.
