Fuses are an important component of electricity components and have been used for a long time. Although they may look small, their role in protecting the grid and maintaining the stability of electricity in the system is of great significance. The fuses used in the electric grid system today are mostly of the 03131-2MXP type, which uses a thin metal strip as a fuse element to bear the maximum current of the system, and when the current exceeds the maximum allowable value, the metal strip will be quickly damaged and automatically disconnected. The broken metal strip of the fuse opens the circuit and cuts off the electric power, so as to protect the security of the system from electric leakage and other accidents.

Application field of 031303-2MXP Type Fuse

Covering a wide range, the 03131-2MXP type fuse is widely used in the electric system of airports, ports, power plants, substations, residential areas and other places. It is mainly used to protect the system from damage caused by large current. Such as the sudden increase of starting current, ignition current, overload current and other protection and reaction control The fuse element used in 03131-2MXP type of fuse is also very suitable for use in places with frequent current switching, since its breaking time can be effectively shortened and the maximum current of the system can be quickly reduced. In addition, it also has advantages such as high electrical endurance and fast response in terms of protecting the circuit of electrical devices from overcurrent or short circuit.

Working Principle of 031303-2MXP Type Fuse

The 031303-2MXP type fuse consists of a fuse element and its holder, the fuse element is made of a piece of thin metal strip, and the fuse holder is a kind of insulated plastic shell. When the system is running normally, there\'s no current in the fuse element, and the fuse holder itself has a certain insulation effect, which keeps the current from leaking to the external environment. If the system suddenly has a large current surge, the thin metal piece in the fuse element will carry this current. Because the allowable maximum current of this fuse is limited, if the current exceeds its limit, it will cause the resistance inside the metal strip to heat up quickly, melting and opening the current path. At this time, the current will be interrupted and the circuit will be cut off.

In addition to the protection of the current, 031303-2MXP type fuses also have a self-locking ability. After the metal strip is broken, it will produce an obvious arc gap. If the power is disconnected, the gap can still remain, and it can still isolate the circuits, preventing the circuit from being reenergized.

Conclusion

031303-2MXP type fuses are especially suitable for use in places with frequent current switching. Their high electrical endurance and fast response protect the circuit of the system from overcurrent or short circuit, and their self-locking ability can effectively ensure the safety of the system. Although the fuse element looks small and simple, its role in protecting the grid and maintaining the stability of electricity in the system is of great significance.
