0217.630H Application Field and Working Principle

0217.630H, also called “Blade Fuse”, falls into the category of “Fuses” and is a type of current-limiting overcurrent protection device. It is mainly used for protecting vehicles’ electrical systems and electrical components against short circuit or overload. As its name indicates, this fuse is flat and has been designed to fit into low profile fuse blocks.

Application Field

Generally, 0217.630H Blade Fuses are used in automotive vehicles in order to avoid, or at least to reduce, any potential hazards connected with high current and drop or interrupt the electric supply right away when set values of current are exceeded.It is suitable where you need to protect smaller and simpler circuits and is commonly used in conjunction with lighting and air conditioning units, as well as with other equipment requiring a secure power supply from the car’s battery.In addition, due to its specific shape, this fuse can also be employed even in narrow and difficult-to-access spaces, such as within the vehicle’s interior fittings, without the need of large and bulky enclosures.

Working Principle

When it comes to the working principle of 0217.630H Blade Fuses, it is actually quite simple, yet efficient. The device consists of a metal strip with two electrical conductors and a plastic body. The strip is usually made of zinc alloy and contains two pull clips at both ends that allow its connection to the rest of the electrical circuitry. When the current flowing through the fuse reaches a certain level, the fuse melts and the circuit is broken.

This is the most important element and its breaking is actually detectable. The breaking point is usually marked on the fuse itself: at the sides of the plastic body, you will usually find two colours to indicate, in some cases even the exact amperage. The colours indicate voltage, amperage rating or a temperature rating.

Final Words

When it comes to fuses, the 0217.630H Blade Fuse is an important piece of hardware that can help to protect vehicles and other electrical components from any potentially hazardous short circuit or overload. The device is simple, efficient and easy to understand, making it the perfect choice for automotive and home applications. Its specific shape and size also allow it to be used in difficult-to-access sites, thus saving time and resources.
