FZN25 FZRN25 12KV 24kV Indoor high voltage electric three pole air vacuum load break switch

Products Description

vacuum load break switch (VLBS) is a type of disconnecting switch that uses vacuum technology to interrupt the flow of current in a circuit. It is commonly used in medium voltage power distribution systems for load breaking and isolation applications.

A vacuum load break switch typically consists of a vacuum interrupter housed in a metal enclosure. The vacuum interrupter contains two contacts, which are separated by a small gap. When the switch is closed, the contacts are pushed together, allowing current to flow through the switch. When the switch is opened, the contacts are pulled apart, creating a vacuum arc that extinguishes the current.

VLBSs are designed to be compact and require very little maintenance compared to other types of load break switches. They are also highly reliable and can operate in a wide range of temperatures and environmental conditions.

In addition, VLBSs have a high breaking capacity, which means they can interrupt high currents without damaging the switch or surrounding equipment. This makes them an ideal choice for applications where there is a high level of electrical stress, such as in power distribution systems.

Overall, vacuum load break switches are a versatile and reliable component of electrical systems and are widely used in a variety of industrial and commercial applications.
