Introduction

A fuse is a type of electrical protection device designed to protect electrical circuits against over-current or short circuit conditions. Fuses work by either melting or blowing, when too much current passes through them. The 0218.040MXP Fuse is a fast-acting, time-delay fuse from Littelfuse. It uses a thermally-sensitive material encapsulated in a glass tube to protect electrical circuits from high-current overloads.

Device Description

The 0218.040MXP Fuse is a Type-3 Midget-sized Fuse with an IEC (257-2-3) configuration. It has a body length of 18mm and a body diameter of 4mm, making it suitable for use in space-restricted applications and crowded control panels. It has a current rating of 20A @ 250VAC and a breaking capacity of 10,000A. The fuse has a ‘U’ marking which indicates that it is legal for use in many countries in Europe, including the UK, and a ‘V’ marking which indicates that it is legal for use in many countries in North America, including the USA.

Application Field

The 0218.040MXP Fuse is used in a variety of electrical applications in both commercial and residential settings. It is typically used to protect electrical circuits from high-current overloads and short circuits. The fuse can be used in appliances, motors, fans, transformers, lights, and a range of other electrical equipment. It is commonly used in equipment operating at very low temperatures, where a fast-acting type of fuse is necessary.

Working Principle

The 0218.040MXP Fuse operates in a similar manner to other fuses. It is designed to automatically open the circuit if the current passing through it exceeds the rated value. When the current passes through the fuse, it causes the thermally-sensitive material in the glass tube to expand, which results in the fuse breaking the circuit. The time-delay feature of the fuse means that it will allow a higher current to pass through the circuit initially, before automatically opening if the current persists after a certain period of time. This helps to protect the electrical circuit from high-current overloads and short circuits.

Conclusion

The 0218.040MXP Fuse is a fast-acting, time-delay fuse from Littelfuse. It has a current rating of 20A @ 250VAC and a breaking capacity of 10,000A, making it suitable for use in a variety of electrical applications. It is commonly used to protect circuits from high-current overloads and short circuits. The fuse operates by allowing a higher current to pass through the circuit initially, before automatically opening if the current persists after a certain period of time.
