Isolator & Switch Disconnectors

Fused switch disconnectors 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.

Fused switch disconnectors 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 switch disconnectors 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 disconnector over a non-fused switch disconnector one 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 overcurrent. 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 switch disconnectors mainly differ depending on the type of fuses they house, the number of poles they have, and the terminal type.
