Description Of Explosion Proof Slow Blow Pico Fuse
This kind of fuse has a very broad range of application, it can be used for a variety of precision power supply, audio video controller, LCD monitor, medical equipment and military products, etc. The fast-acting micro fuses conform to UL248-1 and UL248-14 standards, and obtained the certification of American UR certification and CSA of Canada. The advantages of the fuse include small volume, convenient use, and small installation area. The fuses adopt color ring mark, thus the ampere figures can be seen at a glance. The fuse can also be added with insulation protection to be isolated with other electronic components according to the customer requirements.

How do fuses work?
Fuses are essentiallyfire breaks, points of deliberate weakness that, if power surges through a house’s electrical system, will collapse to prevent damage orfire. This is achieved by the fuse’s central component, a strip or strand of metal which has a lower breaking capacity. The metal’s breaking capacity is the maximum current that can be passed through it safely, while anything above that will cause it to melt and break the circuit. Zinc, copper, silver and aluminium are all commonly used as fuse wire.
The fuse wire is then placed between two terminals, wrapped in a non-conductive material and then put in place. Then, if a power surge happens, the fuse will break, severing the connection, closing the circuit and minimising further damage.
