    Abstract: A time-delay fuse having a fuse element with a series of weak spots surrounded by a loose sand filler. The fuse element is connected to a trigger mechanism by solder or other meltable alloy. The trigger section provides overload protection and the fuse element provides short circuit protection resulting in a time-delay fuse which can be used in places where there are size restrictions.
