Inrush current limiters (ICL), such as MF72-012D11, are used to protect electrical panels and circuit boards against surges of inrush current. This type of surge protection has become an essential component in the design of any electrical system as it is vital for safety and maintenance purposes. The aim of this article is to provide an overview of the working principle and application field of MF72-012D11.

Application Field of MF72-012D11

The MF72-012D11 inrush current limiter is a robust and highly reliable component used in a wide variety of applications. It is designed to reduce the inrush current of AC and DC electrical systems by providing a constant current limit. The limiter can be used in residential, commercial, and industrial applications, such as lighting, motors,mot ion control, UPS, and other applications.

Working Principle of MF72-012D11

The MF72-012D11 inrush current limiter works by limiting the input current to the system, thereby preventing large inrush current from flowing into the system. The limiter uses a unique thermal fuse component, which is designed to heat up gradually as current passes through it. The increasing heat causes the element to melt gradually, creating an effective and reliable thermal fuse that breaks the current connection when it reaches a certain temperature. As soon as the current connection is broken, the inrush current is limited and the system is protected from the damaging effects of high inrush currents that could otherwise cause serious and costly damage.

In addition, the limiter uses an impedance element to further reduce the current flow and restrict the energy passing through the circuit. By combining the thermal fuse and the impedance element, the MF72-012D11 inrush current limiter offers excellent protection against the damaging effects of high inrush currents.

Conclusion

In conclusion, the MF72-012D11 inrush current limiter is an effective and reliable component for protecting electrical systems against harmful inrush currents. It is suitable for a wide range of applications, from residential to industrial, and it ensures a safe and reliable operation of the system. Its working principle is based on the use of a thermal fuse and an impedance element, which together protect the system from high inrush currents and limit the input current to the system.
