Fuse I don’t know if you know this term. In fact, a fuse is a kind of protective device used to protect electricity. It is also widely used. Next, the fuse link supplier will take you to understand the fuse.

What is the function of the fuse link?
It mainly plays the role of short circuit protection in the circuit. The fuse is mainly composed of a melt and an insulating tube (insulation seat) for installing the melt. When in use, the melt is connected in series in the circuit to be protected. When a short-circuit fault occurs in the circuit, the melt is instantly fused to break the circuit and play a protective role.

What is the difference between a fuse link and a fuse?
A fuse link is called a fuse. It can be said that a fuse is a fuse. A fuse is not necessarily equal to a fuse. A fuse is a finished electronic component, but a fuse can be a semi-finished product, that is, an electronic component without forming. So I usually mark the fuse in the catalog instead of the fuse. Fuses represent a much smaller range, while fuses represent a much larger range. There are many types of fuses, and the fuse as a raw material is still very simple. There are roughly two types of fuses on the market at this stage. One is to protect the circuit based on overcurrent, and the other is based on Wenlai protecting the circuit, regardless of the method, its function is that when there is a problem with our circuit, the power supply can be immediately disconnected to protect everyone's equipment.

What happens when a fuse blows?
[1] There is a difference between a current short circuit and current overload: a current short circuit is a direct connection between the live wire and the neutral wire, without passing through electrical appliances, and an almost unobstructed current loop is rapidly generated, and the large current passes through the fuse, and the resistance of the fuse suddenly increases. Thermal energy is instantly fused;
【2】Pulse: When the circuit is started or the power supply is unstable, an instantaneous large current causes the fuse to break; in addition, the screw is not tightened when the fuse is installed, or the fuse is damaged, which will also cause the fuse to blow.
【3】Overload: The load current exceeds the rated current of the fuse, and the fuse will heat up and blow for a long time (generally 1.1 times the rated current will blow in about 1 hour)
【4】Short circuit: a short circuit fault occurs on the line side, and the fuse is quickly broken;

What does a fuse look like?
A fuse (fuse) refers to an electrical appliance that fuses the fuse with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. The fuse is based on the fact that after the current exceeds the specified value for a period of time, the heat generated by itself melts the melt, and then disconnects the circuit; a current protector is made using this principle.

Can the fuse be reset?
The fuse link supplier tells you not recoverable. The reason is that the fuses of the fuses are all disposable. Not recoverable. If you want to save fuses, maybe replace the fuse in the fuse. But it's better to be original.

In fact, a fuse link is a fuse, a fuse is a more popular name, and a fuse is a standard name. We are used to calling glass tubes or lead wires fuses, but fuses are more complicated in structure than fuses.

The fuse is included in the fuse. If there is an indicator mark after the fuse breaks, a component made into a pluggable shape, etc., then the core inside is the fuse.

fuse link supplier Tips: The standard fuse cannot be replaced by a thicker fuse or iron wire, copper wire, aluminum wire, etc. Because the resistance of the copper wire is small, the heat generated is less, and the melting point of copper is high, so it is not easy to fuse.
