Non-Resettable Wire Ended Fuses

Non-resettable wire ended fuses are a type of single use circuit protection device that are can be soldered onto printed circuit boards or carriers. This category encompasses any type of single-use fuse that consist of a fuse body with two wires extended outside of the body.

How do non-resettable wire ended fuses work?

Non-resettable wire ended fuses form part of a circuit and allow an electrical current to flow through them. When a fault such as overcurrent or a short circuit is detected, the metal strip in the fuse body will melt, breaking the circuit and preventing damage. This type of fuse must be replaced after it has blown.

Types of non-resettable wire ended fuses

Non-resettable wire ended fuses differ broadly, mainly in their shape. The fuse body can be a short, fat cylinder or a longer, thinner one, and the wires may extend in parallel both from the same side of the fuse, or in opposite directions from either side of the fuse body. They also differ in their current and voltage rating, and the range of their operating temperature.
