0219.250MXA application field and working principle

0219.250MXA is a type of fuse commonly used in various electrical equipment. It is usually applied to the protection of AC motors, transformers and control circuits. It features with high--speed response, low energy-let-through, high short-circuit current capacity and high breaking capacity. The followings are the main application fields and the working principle of 0219.250MXA:

Application Field

The 0219.250MXA is mainly used in intermediate circuit and overload protection, which suits for the performance of the start-up and running of small and medium-sized motors, transformers, air-conditioners, sensitive electronic equipment and various control circuits, etc. In the mean time, it can also be installed in the circuits with some delicate operation, such as the elevators, power cranes and safety protection circuits.

Working Principle

The working principle of 0219.250MXA is simple: when the fuse is working, it is heated by the electric current on the circuit. If the electric current is more than the rating value and then the heat generated by the fuse is more than the thermal energy, so the current passes through the fusible wire will be cut off, thus achieving the purpose of protecting the electric appliance. When the short circuit or overload occurs, the electric current on the circuit will reach the fuse current value, the fusible wire will be quickly melted and heated, so as to completely cut off the electric circuit.

Performance

0219.250MXA has excellent performance. It can withstand a large current and have a high breaking capacity. It has a high short-circuit current capacity, which contributes to a better protection of the circuit and electrical appliances. The melt-off time is fast, which can provide a higher response speed. Moreover, it has a low energy-let-through to ensure the reliability of circuit operation.

Conclusion

0219.250MXA is a type of fuse commonly used in various electrical equipment. It is mainly used in intermediate circuit and overload protection, including the start-up and running of small and medium-sized motors, transformers, air-conditioners, etc. In addition, it also provides excellent performance, such as a high breaking capacity, a high short-circuit current capacity, a fast melt-off time and a low energy-let-through.
