Inrush current limiters, also known as ICLs, are a type of electromechanical device designed to protect equipment from excessively high inrush current. The MF72-400D9 is an ICL specifically developed for use in high power applications. This article will discuss the application field and working principle of the MF72-400D9 ICL.

Application Field of the MF72-400D9

The MF72-400D9 is a high power inrush current limiter designed for use in a variety of industrial and commercial applications. This ICL has a maximum rated current of 400A and an adjustable surge current limiting range of 5-30A. The MF72-400D9 is most suitable for applications where high inrush currents are expected, such as motors, compressors, transformers, servers, and other industrial equipment.

The MF72-400D9 has a wide operating temperature range of -40°C to +105°C. This makes it suitable for use in a variety of environmental conditions, including extreme hot and cold climates. The ICL also has a wide range of IEC certification including CE, CB, VDE, UL, PSE, SAA, and BSMI. This makes it well suited for use in domestic and international applications.

The MF72-400D9 has a compact design which makes it easy to install and integrate into existing systems. It also has an easy to use interface for configuring and monitoring the device.

Working Principle of the MF72-400D9

The MF72-400D9 is an integrated inrush current limiter which works by limiting the surge current upon system startup. Upon startup, the ICL creates a back-EMF field which is proportioned with the current flow. The back-EMF field acts to limit the surge current, thus preventing any potential damage to the system due to an over-current situation.

The MF72-400D9 uses a thermal disconnect device to ensure that the system does not overheat. This thermal disconnect device is triggered when the internal temperature of the device reaches a set threshold. Once the device has been triggered, it will cut off power to the system to prevent any further damage.

The MF72-400D9 also has a built-in circuit breaker which provides additional protection against over-current situations. This circuit breaker is designed to disconnect power in the event of an over-current situation and can be reset manually once the power has been disconnected.

The MF72-400D9 is designed to provide reliable protection for high power systems. It is especially effective in applications where rapid surges of current are expected. The ICL also provides excellent protection against over-current and over-temperature situations. The built-in circuit breaker and thermal disconnect device ensure that the system does not suffer any damage due to excessive current flow.
