Fuses
Fuses are necessary parts of electrical systems, giving overcurrent protection by interrupting excessive current flow to keep circuits and equipment from being damaged. These devices, which include kinds such as cartridge fuses, glass fuses, and auto fuses, work by utilizing a fuse wire or link that melts when the current exceeds the rated capacity, effectively breaking the circuit. Their use is widespread in many areas, like cars, factories, and homes, where they help keep the safe operation of electrical equipment running smoothly and without excessive interruption.
Distinct functions are served by automotive fuses and medium-voltage fuses. The former is found in vehicle electrical systems, while the latter is used in applications requiring high power, like transformers and motors. Fuses must be selected according to voltage, current rating, and breaking capacity—more or less, an electrical "must not exceed" specification—that guarantee fuse compatibility with diverse vehicular and industrial power systems. Incandescent burn-out indicators (a good way to tell a fuse is blown) are available on some modern fuses; the visual indication makes it quicker and easier to find problematic fuses.

Mersen 550TPMOVTS SPD - TPMOV 550V Short Leads Microswitch Visual Tabs 50 kA TS
$56.00
$103.99
Mersen’s TPMOV technology eliminates common failure modes that occur in the field with standard metal oxide varistors. Internally each unit is comprised of a voltage clamping device and a disconnecting apparatus that monitors the status of the metal oxide disk, making the TPMOV surge suppression component a fail-safe device. In the event of an overvoltage breakdown, the metal oxide disc is securely disconnected from the system power by an arc shield. Upon failure, the TPMOV surge suppression component is also equipped with a visual pin indicator as well as a normally open micro-switch, providing remote indication if applicable.
