What are the most common car fuses? (6 Types of Car Fuses)

Car Fuses are the essential components designed to protect the electrical system from short circuits, power surges, and excessive loads.

There are fuse boxes located in the engine compartment, and the passenger compartment section featuring various fuses. Every fuse has its specific role and function.

In this blog post, we will find out what are the most common car fuses used. We will also discover the importance of fuses.

Without further ado, let’s get started.

Types of Car Fuses

There are different types of car fuses equipped to protect several electrical components in a vehicle. Some common car fuses include Blade Fuses, Mini Blade Fuses, Maxi Fuses, Glass Tube Fuses, Ceramic Fuses, and Resettable Fuses.

Now, let’s discuss these fuses in detail.

Blade Fuses

One of the most common fuses used in the vehicle is the blade fuses. These protective devices are designed in a rectangular shape with two flat blades on the top, and a transparent plastic body as shown in the image above.

Blade fuses are specially used to protect electrical components like wipers, audio systems, headlights, and others. 

These fuses are available in six different physical dimensions including Micro2, Micro3, LP-mini (APS), Mini (APM/ATM), Regular (APR/ATC/ATO/ATS), and Maxi (APX).

Mini Blade Fuses

Mini Blade Fuses are identical to Blade Fuses however, they are smaller in size. The shape of the mini blade fuse is rectangular, and the physical dimensions are compact.

These fuses are used to protect electrical components like power windows, auxiliary outlets, interior lights, and other electrical accessories in newer vehicles.

Maxi Fuses

There are specific fuses known as Maxi Fuses designed to handle higher amperage levels. These fuses are larger in size, and feature a plastic body with two metal blades on the top.

Maxi Fuses are typically located in the engine compartment fuse box, and are responsible for protecting high-current electrical components like a cooling fan, air conditioning compressor, power seats, and others.

Glass Tube Fuses

Glass Tube Fuses are generally used in old car models. These fuses have a cylindrical shape with a glass tube, and metal caps on both ends.

The major role of glass tube fuses is to protect components like the alternator, ignition system, and starter motor.

Ceramic Fuses

Ceramic Fuses look like glass tube fuses but are manufactured with a ceramic body. These fuses are used to offer better protection against high-temperature conditions.

Vehicles requiring demanding electrical systems are equipped with ceramic fuses. Fuel Pumps, ABS systems, and Power Steering are some of the crucial components protected by ceramic fuses.

Resettable Fuses

Resettable fuses are commonly known as circuit breakers. These fuses are unique compared to others because it doesn’t need replacement after a fault.

When excessive current flows through them, they automatically trip and then reset once the issue is resolved. These fuses are commonly used in sensitive electronic systems, such as power windows, seat heaters, and entertainment systems.
