Inrush Current Limiters (ICL) are designed to protect electrical components from suffering the consequences of sudden large surges of energy in the form of an inrush current. This type of protection is necessary for components such as semi-conductors, motors, relays, transformers, and other types of actuators. The purpose of an ICL is to reduce the maximum instantaneous current that can flow through a given circuit. One of the most commonly used and reliable ICLs is the MF72-020D11.

The ratings of the MF72-020D11 Inrush Current Limiter (ICL) are impressive, with a voltage rating of 1500V AC/ DC and a current rating of 20A. Additionally, the manufacturer lists an energy rating of either 0.3J or 0.6J for optimal performance. This ICL utilizes two electrodes for the discharge of energy, and the internal electronics are designed to operate in a linear mode. When the load current exceeds the rated current, the internal electronics will detect this and activate the ICL. The ICL then converts the input AC energy to DC energy, which helps to reduce the instantaneous current.

The application field of the MF72-020D11 Inrush Current Limiter (ICL) is quite vast, as it is often the device of choice for commercial, residential, and industrial power distribution applications. It can be used to control inrush current in circuits with AC switchgear, capacitor banks, brakes, solenoids, shock absorbers, transformers, and other actuators. Additionally, this ICL is often chosen for use in LED lighting systems, power supplies, and AC drive systems.

The working principle of the MF72-020D11 ICL is fairly simple to understand. When the current within the protected circuit exceeds the rated current, the ICL will detect this and activate. The ICL then converts the AC energy to DC energy, which helps to reduce the instantaneous current. This conversion helps to reduce and eliminate any electrical shock or other damages that could occur due to an inrush current. When the overcurrent is gone, the ICL will immediately deactivate and the power will return to normal.

The MF72-020D11 Inrush Current Limiter (ICL) is a reliable and effective product when it comes to protecting circuits from inrush currents. It is a widely used ICL and is used in a variety of fields and applications. As previously mentioned, its voltage and current ratings are quite impressive, and it utilizes linear mode operation for the best performance. Its working principle relies on the conversion of AC energy to DC energy for reducing the instantaneous current, thus helping to protect the circuit from shock and other damages.
