Fuse Switch Disconnectors

Fuse Switch Disconnectors, also known as fused isolator switch disconnectors, are devices used to safely isolate electrical circuits for maintenance or service. Fused switches typically contain one or more fuses inside the same enclosure so that it is easy to select and isolate a particular part of the circuit.

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.

At RS, we offer a wide selection of Fuse Switch Disconnectors from leading brands such as Siemens, Eaton, ABB, and Schneider Electric, as well as our own trusted RS PRO range. We also stock a comprehensive range of Isolator Switches for related applications. With RS, you can rely on Next Day Delivery to keep your projects on schedule.
