30A Standard Car Auto Blade Fuse 30 Amp ATO - Pack of 10

Product Information

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. Therefore, fuses are defensive or protective components that take the shot for the components they are guarding. Every vehicle has 30 amperage fuses. But what does a blown 30 Amp fuse look like? What does a blown house fuse look like? Blade-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. By using a slow-blow fuse you can bypass this false tripping problem. A slow-blow fuse fulfills the overload demand of applications without bursting itself. It bursts only when the overcurrent situation sustains an electrical path.

When comparing a new 30 amp fuse with a blown one, it is very clear to see the difference. The new 30 amp fuse has a metal strip or wire running through the middle of the fuse. Different components in your vehicle will require different amperages. For instance, components that don’t require a lot of electrical current like lights will have a 10 amp fuse. However, components that do require more electrical current such as the AC or ignition and possibly many others, will require a 30 amp fuse. What Does a Blown 30 Amp Fuse Look Like

There are three methods of testing 30-amp fuses. The most common method is using a multimeter. We’ll explain that in a moment. But first, let’s look at how to tell if a fuse is blown without a multimeter. Visual inspections So, when the current is too strong, the fused element inside(metal strip or wire) of the 30 amp fuse heats up and breaks. The breaking action disconnects the circuit which means electricity can’t flow through it anymore and can not damage the main component. Look at the diagram on the fuse cover to aid your search. Next, locate the blown 30-amperage fuse and pull it off. You can either pull the blown fuse with a pair of pliers or by hand. Depending on your vehicle, the fuse may have bolts on it. If that’s the case, depress the fuse to expose the bolt and take them off. Step 3: Test the fuse 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.

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 replaced Look for the color code to identify the type of 30 amp car fuse. Blade fuses use a standard color scheme. Some fuses also feature embossed numbers. Fuse boxes are often in dark corners and dirty engine bays, so knowing the colors will make your life much easier. A blown 30 amp fuse will look like having a metal strip or wire that is disconnected in the middle of the fuse itself by being blown from over current. 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.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: Circuits that use 30 amps or more can have overcurrent safety protection provided by a 30 amp car fuse. It is the weakest link in a circuit, and a blown fuse will prevent high current from getting to the main components. The fuse rating is listed on the fuse. Your car’s fuses should match it. The wrong fuse can cause a component to fail, which could lead to the problem getting worse. More importantly, if the amperage rating on the fuse is too high, components may fail before the fuse does. On some vehicles, there are two fuse boxes. As shown in the photo above, right above the handle for the hood there is a fuse box. However, the 30 amp fuse is usually located under the hood. So, to gain access to the fuse box, you will need to open the hood by pulling the hood latch. 3. Locate and open the fuse box
