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

Product Information

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

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. 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 Amp fuses in cars are used to provide overcurrent safety protection on electrical circuits that uses 30 amperages. Examples are the ignition and the AC. For a 30 amp fuse to effectively carry out its safety job, it serves as a fragile joint in the electrical circuit. A blown 30 amp fuse typically appears as a disconnected or broken metal strip or wire in the middle of the fuse, often accompanied by signs of physical damage, discoloration, darkening, or burning. Pull out the fuse with the fuse puller or a pair of pliers. Look at the metal strip across the fuse terminals. If the strip is broken, you have a blown fuse. If the metal strip is still intact, the fuse is okay. Using a test lightThe last and most common method is using a multimeter. This method is more suitable for those fuses in a box like the pink 30 amp fuse with a blue cover. 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

If the visual inspection is inconclusive, use a multimeter to test whether the fuse is working or not 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. 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. Get your multimeter and set it to ohm settings. First, make sure you fix the probes on the multimeter properly. Then, touch the two probes and record the reading. You should get the same or similar reading when you test the fuse. 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.

When this happens, it is important to replace the fuse with one that matches the amperage and voltage rating of the original fuse. Gently slot the new fuse into position in the fuse panel, taking care not to damage it or any surrounding fuses 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.
