Fuses are important components in electrical circuits, and this article focuses on the application fields and working principle of 045401.5MR fuse.

Application Fields of 045401.5MR Fuse

The 045401.5MR fuse is highly applicable in the field of electrical appliances, electronic products, electrical circuits, and other fields that involve the current-limiting protection of electric wires. It is suitable for the protection of industrial automation, renewable energy, power distribution and other systems with circuits of 0.4-5A current.

This type of fuse is especially suitable for the renewable energy field. For example, 045401.5MR fuses are used in the energy storage equipment of solar energy systems, wind and hydroelectric systems, and can protect the batteries. It can also help protect electric motors in electric forklifts, and other commonly found in renewable energy systems. Furthermore, this type of fuse can also be used to effectively protect electrical wires in photovoltaic projects.

045401.5MR fuses are also frequently used in many electronics. For instance, it can help protect electronic control boards contained in various household appliances because it supports a maximum of 5A current and is fuse-compliant. Moreover, fuses of this type can also provide current limiting protection for consumer and industrial electronics, and help maintain the safety of the products. In addition, it can be used with various products such as transformers, switches, air conditioners, refrigerators, washing machines, computers, and communication equipment.

Working Principle of 045401.5MR Fuse

The 045401.5MR fuse is a cylindric integrated fuse with a diameter of 4mm and a length of 40mm. It uses the principle of melting fuse film to operate. When an electrical fault occurs in the circuit, the fuse reacts instantly to high current, melting the fuse and breaking the circuit. To ensure connection and prevent damage, it is generally composed of tin-plated copper tube, oxidized metal parts and thread. In addition, the fuse element is made of an organic material, such as the nitrile-butadiene rubber, which can be connected with the circuit and prevents the current overload.

When an overload takes place, the fuse acts as a current limitation device. It limits the current to a safe level, allowing for the smooth flow of current and protecting the sensitive components in the circuit. The 045401.5MR fuse is designed to operate at currents between 0.4A and 5A and is typically rated to operate at a 25A peak current. The 045401.5MR is also designed with a thermal fuse element, which further improves the operating temperature range.

Aside from providing a safe current flow, the 045401.5MR fuse also helps protect other components in the circuit from damage due to overload. It is usually equipped with a red indicator, which will light up when the fuse is damaged due to overload. This helps alert users to any faults in the circuit, protecting them from electrical hazards.

Conclusion

The 045401.5MR fuse is widely used in various applications such as renewable energy, industrial automation, consumer electronic, and power distribution. Its working principle relies on melting fuse film, which allows for the safe flow of current and helps protect other components in the circuit from damage due to an overload. When an overload occurs, the red indicator will light up, alerting users to the fault and protecting them from electrical hazards.
