142.5631.5402

Fuses are relied on to protect electrical installations and circuits especially those that are attached to potentially hazardous electrical products. It\'s important to understand the construction, application field, and working principle of fuses such as the model number 142.5631.5402.

Construction and Design

142.5631.5402 fuses are made up of zinc and other alloys and are housed in a protective case. The fuses feature pressure relief vents that allow for the quick and easy removal of air without removing the fuse, and provide optimum protection against corrosion. The main components of the fuse include the terminal, the body, the lead wire, and the breaker or fuse holder.

The outer case of the fuse protects the inner components from the elements, which is essential for it to remain in working condition over time. The terminal and lead wire are also designed to absorb mechanical shock and vibration so that they never become compromised due to external factors. The breaker or fuse holder is designed to allow easy access to the terminals so that you can easily replace the fuse, if needed.

Application Field and Working Principle

142.5631.5402 fuses are often used in AC circuits up to 20A and as low as 15A. The fuse’s working principle revolves around thermal and electrical properties and is used to protect devices from overloads and short circuits. The fuse is composed of a special wire that is heated quickly by electric current and causes a decrease in electrical current until the power supply is completely shut off. This helps to prevent accidents and damage to electrical components.

When electric current passes through the wire, the temperature of the wire rises. If the wire is heated excessively due to an overload or a short circuit, the wire melts and disconnects the circuit. This cutoff helps protect the device and the entire power supply from further damage. The fuse automatically resets itself after the wire cools down, and the power supply is switched back on.

The temperature rating of the 142.5631.5402 fuses is important to note because the higher the temperature rating, the less likely the fuse will be damaged due to an overload or short circuit. The temperature rating of this fuse is up to 200°C and it is suitable for applications with temperatures up to 125°C.

Conclusion

The 142.5631.5402 fuse is a reliable and safe product designed to protect electrical installations and circuits from overload and short circuits. The fuse’s construction and design make it suitable for use in a variety of AC circuits, and its temperature rating makes it an optimal choice for applications with temperatures up to 125°C. Knowing its application field and working principle is key to properly using this fuse as part of your electrical system.
