Some car applications by nature need a large inrush current at a start-up that exceeds a fuse’s pre-determined rated current value. If a fast-blown safety switch is used, it could blow immediately resulting in the wrong nuisance blowing. There are multiple different types of automotive fuses. Varying types and sizes will be needed for dealing with specific electrical equipment within the vehicle. For this reason, it is common for a single car to include many different types of fuses. In the second design, the bottom of the plastic housing body is kept closed, sealing the fuse-element from the atmosphere (To protect the fuse-element from moisture), called the ATC fuse. Where “C” stands for “Closed” housing space between the two blades of the fuse. As explained above, the first steps to replacing a car fuse are to locate the fuse box and the blown fuse and buy a new fuse of the same type, size, and current rating. Once you have the new fuse, you will need to carefully insert it into position within the fuse box or housing. Make sure to insert it into the correct location where the blown fuse was situated.

The purpose of the fuse is to protect the wiring harness and electrical components of the vehicle from damage. The fuses feature an internal fuse element that melts, when a high amount of current passes through the fuse element, causing the breaking of the circuit. Fuse Element Width Size Gently slot the new fuse into position in the fuse panel, taking care not to damage it or any surrounding fusesBlade-type fuses are also known as Plug-in fuses, developed first in the 1970s. It is the most common automotive fuse type used in the car industry. A blade fuse is a type of automobile fuse consisting of two blades/prongs and a fuse-element (A metal wire connecting both blades) encased in a semi-transparent color-coded plastic. The purpose of a transparent plastic housing is for easy identification of a broken fuse. Fuses are designed to blow preventing the electrical circuit from burning. There are hundreds of vehicle fuse varieties and designs. automobile fuse types vary in terms of make and model. Each fuse has its specification, design, and installation depending upon the need of the circuit. The major types of fuses are either of these: It has the characteristics of built-in time delay and low voltage drop. Its fuse-element material is designed to slowly raise its temperature when the current overruns the electrical path, which protects the fuse from false blowing. Thus, a slow-blow fuse melts after some time in an overload event. Also, bear in mind that the plastic housing body of a fuse can repeat and makes you confused. In a regular blade type fuse, the 10 amp fuse color is red. The same Red color in the maxi-blade fuse represents 50 amp. These are the cautions, one must keep in mind while replacing fuses, especially in worry situations. There are various dimensions, colors, and types of fuses that come in to represent its characteristics.

A broken fuse in a car can indicate a major problem. When a fuse has blown, it shows some symptoms which indicate an issue with a fuse including a loss of power to one or more of the vehicle’s functions or accessories, such as windshield wipers, power windows, or radio. The surest sign of a broken fuse is if the car’s electrical system stops working as the fuse box controls the electrical system of the vehicle. If the fuse is working correctly, this means the problem does not lie with the fuse. If the fuse has blown or is not working correctly, it will need to be replacedWe will explain the different car fuse types further on in this guide, but the specific type of fuse your car needs will depend on a selection of factors. This includes the make and model of the vehicle, the existing fuse, and the electrical circuit or equipment it is designed to protect. Electric vehicles (EV) fuse is a high-voltage, high-current rating fuse. It is used in high-voltage batteries or hybrid electric vehicles for protection from overcurrents.

In the first design, the bottom of the plastic housing body of a fuse is kept open, exposing the fuse-element to the atmosphere, called the ATO fuse. Where the “O” at ATO stands for “Open” housing space between the two blades of the fuse. First let me make it clear that ATO/ATC only relates to the design of the housing body of the fuse, not to anything else. Car manufacturers made plastic housing bodies of a fuse in two different designs.
