MF72-200D5

Inrush Current Limiters (ICLs) are designed to prevent large inrush currents when a device is first switched on. Such a device is the MF72-200D5 specifically designed to limit the inrush of AC and DC circuits.

The MF72-200D5 is an ideal solution for controlling inrush currents in AC circuits. Its unique design features two thermistors and an air gap that combine to limit inrush current below a specified level. The thermistors respond to changes in temperature resulting from the inrush current and open up to allow the current to flow through the air gap. This limits the current level to a safe value that ensures reliable operation of the AC circuit.

The MF72-200D5 also offers enhanced protection to DC circuits. It features a construction of two air gaps connected in series. As the DC current passes through the first air gap, it is gradually reduced. The second air gap further reduces the current levels and provides protection from excessive DC current. This ensures that the DC circuit is protected from any damage caused by overvoltage or over current.

The MF72-200D5 has several features that make it suitable for a wide range of applications. It has an adjustable pre-set current limiting level that can be tailored to specific circuit requirements. It also features a high voltage tolerance and an operating temperature range of -40°C to +85°C. Additionally, it offers a high surge capability of 20kV/8kA and a high temperature performance of -40°C to +105°C.

The MF72-200D5 is an ideal solution for controlling inrush currents in AC and DC circuits. Its unique construction and features make it suitable for use in a variety of applications. It provides reliable current limiting solutions that ensure the safety of the circuits and ensure that they operate properly in a wide range of temperatures. The adjustable pre-set current limiting levels also allow customers to tailor the device to their specific circuit requirements.
