BDS240 is a specialty disconnect switch component designed for fast medium and high voltage circuits. It is applied in various power supply systems and electric power transmission and distribution networks. In this article, we will discuss the application field and working principle of BDS240 disconnect switch.

Application Field: BDS240 disconnect switch can be used in different environmental conditions, such as wet, dusty, damp, corrosive, and so on. It can handle very fast short-circuit current thanks to its multiple contacts and breakable structure. The large contact area can provide large-degree of contact force, and the designed-in reference protective cover can effectively prevent atmospheric corrosion. In addition, it features superb epoxy power arc protection and permanent open switchable.

Working principle: The BDS240 disconnect switch opens by manually turning the handle or running the actuator motor. This rotating handle or motor will rotate the shaft inside the switch. The shaft is connected to the internal mechanism which will rotate the movable contact parts, thus causing the two parts of the contacts to separate from each other and the switch to open. The contacts will be prevented from being released because of the elastic force of the spring. When the switch is turned off, the movable contacts will be forced back into contact with the stationary contacts and the switch will be closed.

The horizontal handle of the switch is also designed to provide emergency shutdown when the need arises. This feature helps shorten the time for executing emergency shutdown procedures, thereby protecting the disconnect switch components and the interconnected power equipment.

Conclusion: BDS240 disconnect switch is an ideal choice for medium and high voltage circuits. Its optimized design, reliable performance and safety features make it the optimal choice for a wide range of electrical applications. With its larger contact area, arc protection and reference protective cover, the BDS240 disconnect switch is the ideal choice for any circuit.
