What Do You Need to Know about Automotive Fuses
For automotive fuses, let's first understand: fuses are common names, their scientific name is fuse, but we usually refer to them as fuses. Their basic function is to protect the circuit when overcurrent occurs.
Generally speaking, fuses mainly have two important parameters: rated current and rated voltage. We usually choose the corresponding specifications of fuses based on the current and voltage of the circuit. Automotive fuses generally adopt a plug-in design, with a plastic outer shell wrapped in a molten structure made of zinc or copper, and a metal melt connected to the pins.
The specifications of automotive fuses are generally 2A to 40A, and there will be a label at the top of the fuse. In general, fuses with different amperes have different colors, and according to international standards, we can identify the ampere number by color. For example: 2A gray, 3A purple, 4A pink, 5A orange, 7.5A coffee, 10A red, 15A blue, 20A yellow, 25A colorless transparent, 30A green, 40A deep orange.
Because every device in a car is equipped with a fuse, and there are many parts and equipment in the car, to facilitate future maintenance, each car will have a fixed place to collect all the fuses, which is called a fuse box.

Selection Process of Fuses
This article tells about the selection process of fuses.
The Selection of Miniature Fuses
Miniature fuses are primarily used in digital cameras, laptops, mobile phones, and other electronic products. From traditional glass tube fuses to miniature fuses, the selection focus varies slightly due to differences in product technology. The selection of miniature fuses involves the following elements.
Why Do Fuses Have High Resistivity
A fuse is a wire made of lead antimony alloy with a lower melting point and a lower resistivity. The more voltage constant resistance can be compared, the more it can detect micro current resistance that exceeds the working range. A high current is required to fuse the resistance, which can burn out the electrical appliance and prevent it from melting. Some principles use the current thermal effect fuse to control the current flow and allow the current to flow.

Selection of Current Fuses in Automotive Circuits
In automotive circuits, the selection of current fuses is of great significance for ensuring the safe operation of the vehicle. There are several key factors to consider when choosing a current fuse for an automotive circuit.
Essential Knowledge for Selecting Automotive Fuses
When a certain overload current passes through, the heat generated is radiated to the surrounding environment through the melt and shell, and the heat dissipated through convection, conduction, and other means gradually reaches a balance with the heat generated. If the generated heat is greater than the dissipated heat, the melt temperature can increase; When the temperature reaches or exceeds the melting point of the melt, the melt melts, fuses, and cuts off the current, playing a role in safety protection of the circuit.

Self Recovery Performance and Working Process of Self Recovery Fuses
Traditional fuses are installed in circuits. When an overcurrent occurs due to a fault or abnormality in the circuit, the fuse itself melts to cut off the current and protect the circuit. However, due to the fact that traditional fuses can only protect once and need to be replaced if burned out, some products still cannot resume operation after troubleshooting or abnormal overcurrent disappears. As a new type of overcurrent protection device, the self-recovery fuse has the function of automatic recovery, which can meet the performance requirements of similar applications.
