The overload fuse link is prepared from a solder alloy and is directly attached to the interior of one of the cartridge fuse terminals. The overload fuse link has an open bore opening at one end and a connector extending from the other end. the cartridge fuse which uses the fuse link also has an insulator through which the connector passes and the insulator separates the short circuit fuse link from the body section of the overload fuse link wherein when there is an overload, the fuse link connector electrically separates from the fuse link body section.

Why it's free to use
- Filed January 11, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 11, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 11, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
