Non Resettable Fuses

Non-resettable fuses are single-use circuit protection devices that break a circuit when a fault is detected, offering protection to vital components. This type of fuse is designed to be mounted directly onto a printed circuit board (PCB). This type of fuse is for single use, with the fuse body and two wires that extend outside the body.
