DDO Fuse Tubes

Fuse tubes, also called fuse cartridges are an insulating tube which houses a replaceable fuse element for fuse link. When the fuse link blows, the fuse tube drops out of place opening the circuit, and hangs from a hinge on the lower end. This hanging fuse holder provides a visible indication that the fuse has operated and assurance that the circuit is open. The circuit can also be opened manually by pulling out the fuse tube using a hot stick.

Fuse tubes are typically made out of a fibreglass tube with conductive contact points.
