# Fuse Breaker# The function of the fuse is to protect the current. The fuse is composed of a melt and a fuse tube, which are connected in series as a metal conductor in the circuit. When the current exceeds a certain value, the fuse will generate heat to melt the fusant, thereby breaking the current and achieving the protection effect. Fuses are widely used in various electrical and electrical equipment due to their simple structure and convenient use.
A fuse refers to an electrical appliance that uses its own heat to fuse the melt and disconnect the circuit when the current exceeds the specified value. The fuse is based on the current exceeding the specified value for a period of time, using its own heat to melt the melt, thereby breaking the circuit; a current protector made by using this principle. Fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As a short-circuit and over-current protector, it is one of the most commonly used protection devices.
The fuse is actually a short-circuit protector, which is widely used in power distribution systems and control systems, mainly for short-circuit protection or severe overload protection. A fuse is a simple and effective way to protect electrical appliances. It mainly plays a role of short-circuit protection in the circuit.
The fuse is mainly composed of a melt and an insulating tube (insulating seat) for installing the melt. When in use, the fuse is connected in series in the circuit to be protected. When a short-circuit fault occurs in the circuit, the fuse is instantaneously fused to break the circuit, which plays a protective role.
The function of the fuse in the circuit is over-current protection, which can also be called short-circuit protection.
When a short circuit occurs, the current in the circuit is the largest at this time. This current value is undoubtedly far exceeding the rated current of the equipment. If the circuit is not cut off in time at this time, the electrical equipment will soon be burned out due to the high current, so in order to Cut off the circuit in time to protect the equipment from damage. The principle of using the fuse element is that a large current can be generated in the circuit at the moment, and the fuse fuse will be blown quickly before the equipment is damaged, so as to achieve the purpose of cutting off the circuit.
