Abstract: A precautionary timer for installation in a kitchen range, as a replacement of a plug-type fuse protecting one of the heating elements of the kitchen range. In a first aspect of the invention, the precautionary timer comprises a threaded fuse stock having first and second electrically conductive terminals set apart from one another, and conductive segments mounted inside the threaded fuse stock and connected to the first and second terminals. A timing unit comprising a low voltage solid state timer and an electronic switch is also mounted inside the threaded fuse stock. The solid state timer is powered by a current transformer sampling power from the current flowing in one of the conductive segments. The semiconductor switch is connected in series with the conductive segments and the first and second terminals, for selectively electrically connecting and disconnecting the first and second terminals to and from one another.
