    Fuse Switch Disconnectors

    Fused switches disconnectors/switch fused isolators are devices used to ensure that a circuit is completely powered down in order for it to be serviced or maintained. They isolate a given part of the circuit by cutting off its electrical supply, making it safe for service or maintenance. You can find out more in our complete guide to isolators and switch disconnectors.

    Fused switches contain multiple fuses inside the same enclosure so that it is easy to select and isolate a particular part of the circuit. For example, an isolator switch can be used in a substation to physically disconnect any circuit when repairs are being carried out.

    What are fused switch disconnectors used for?

    Fused switches protect workers performing maintenance on part of an electrical circuit as well as preventing damage to the circuit itself. The advantage of using a fused switch over a non-fused switch is that it can provide a higher level of safety compared with unfused disconnectors, as the fuse blows in the event of breaches such as short circuits or over currents. This makes it certain that that part of the circuit cannot have current flowing through it while being worked on.

    Types of fused switch disconnectors

    Fused switches mainly differ depending on the type of fuses they house, the number of poles they have, and the terminal type.
