Fused switch disconnectors are used to ensure a circuit is completely shut down for servicing or repair. By cutting off its electrical supply, they isolate a give section of the circuit, making it secure for maintenance or repair. Fused switch disconnectors contain multiple fuses within the same enclosure so that a particular part of the circuit can be easily selected and isolated.

What is the purpose of a fused switch disconnector?

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.

Protecting workers who conduct part of the electrical circuit maintenance, as well as avoiding damage to the circuit. The benefit of using a fused switch disconnector over an unfused switch disconnector one is that it will offer a higher degree of protection compared to unfused disconnectors as the fuse will blow if there is a short circuit or overcurrent.

The fused switch disconnectors vary mainly depending on the type of fuse they hold, the number of poles they have and the type of terminal.
