Automotive fuses - popular types and characteristics of fuses

Every electrical circuit must be protected from sudden surges in voltage and current. Automotive fuses are installed in cars, the task of which is to catch overloads and break the circuit. Thus, they protect devices from irreversible damage. What are the types of these necessary elements in the car? How do you know if they are burned out? You will find all this in our article!

Types of fuses installed on cars

The place where these small elements are mounted is the car fuse socket. It is in it that the protection of individual electrical circuits of the car is located. In the socket you will see many fuses of different colors. Why do they look like this? The colors should indicate the level of security.

Fusible colors - what do they say about protection?

Each security level is indicated by a different color. The colors of car fuses symbolize levels of safety. Miniature and conventional automotive fuses are in this division:

• gray - 2A;
• purple - 3A;
• light brown or beige - 5A;
• dark brown - 7.5 A;
• red - 10A;
• blue - 15A;
• yellow - 20A;
• white or transparent - 25 A;
• green - 30A;
• orange - 40A

fuses for car in maxi size it is:

• green - 30A;
• orange - 40A;
• red - 50A;
• blue - 60A;
• brown - 70A;
• white or transparent - 80 A;
• purple - 100A

Automotive fuses - types of elements by size and heat

What other types of automotive fuses are there? Fuses in a car can be distinguished by size. Electrical installations of cars are of 3 types:

• mini;
• normal;
• maxi.

Most often, you will come across the first two types of fuses. Usually they are located inside the car and are designed to protect low-current circuits. The maxi type protects devices operating at a higher current.

Characteristics of fuses installed in cars

Looking at one selected fuse, you will notice several constants. This includes:

• 2 legs;
• insulation of a certain color, usually translucent;
• connecting legs of wires, filled in with insulation;
• amperage mark on the top of the fuse.

Automotive fuses and how they work

These minor safety features are designed to protect devices from excessive current. Therefore, each of them is marked with the corresponding symbol with the letter A (amperage). When the permissible current is exceeded, the fuses of the car blow out. This ensures that the device does not receive excessive power caused by a malfunction. Thus, the components are protected from irreversible damage.

Mini, normal and maxi car fuses - how to recognize a blown one?

The first symptom is quite obvious. When a device in a car is not working, it more or less means that power is not reaching it. Can you test it? To find a place for the fuses, you need to remove the blown grip. Unfortunately, you will have a hard time recognizing which one was destroyed if you look from above. So first you have to take it out. But is it necessary to do it blindly?

Automotive fuses - marking on the body

If you want to know which car fuses have blown, look at the description on the socket cover or on the Internet. There you will find a diagram of the location of individual fuses and their description, assigned to a specific device in the car. Once you know which fuse is bad, you can easily find it.

Types of fuses and their replacement after a blown

Automotive fuse markings visible in the manual will allow you to locate the blown one. Use the grapple to effectively remove it from the slot. Usually there won't be enough space in the security zone to grab a particular element with your fingers. When you look at a damaged fuse, you will immediately see that it is broken. In plastic insulation, you will see characteristic traces of burnout. Replace the burnt element with the same one with the same amperage.

Why should you have a set of automotive fuses in your car?

It's simple - you never know which one might burn out. Therefore, it is best to take several pieces of this fuse with you. Maybe a kit. The characteristics of the fuses that we have presented are more likely to convince you of this. Blown car fuses will let you see the problem in the car's electrical system. Do not underestimate the problem if one or another protection regularly burns out.

As you can see, automotive fuses are small items, but extremely valuable. The classification we have shown will allow you to easily distinguish between individual elements and their current strength. If you have an elemental burnout adventure, don't worry. Replacing fuses in a car is very simple and you can handle it without any problems. The biggest trouble can only be finding an outlet with protective functions. It is usually located under the hood near the battery or under the steering wheel.
