Inrush current limiters (ICLs) are electrical components used to protect circuits from high inrush current during switch-on. B57238S0220M000 is one example of an ICL. This device is specifically designed for switching power supplies, motors, and other applications with high start-up current. In this article, the application field and working principle of the B57238S0220M000 will be discussed in detail.

B57238S0220M000 is a bidirectional, fixed-biased, A.C. and D.C. rated ICL with very low on-state resistance. It is designed to provide an unrestricted inrush current up to 24A at a peak voltage of 800VAC (RMS). The device is fully insulated to protect against contact electric shock and offers a wide operating temperature range of -40 to 105°C, making it suitable for a variety of industrial and commercial applications. Other features include an internal thermal fuse for over-temperature protection and an integrated surge protection circuit for increased reliability and life cycles.

The B57238S0220M000 has a liquid cooled “dry-operation” configuration, allowing the device to be used at higher currents and voltages than a regular inrush current limiter. This additional cooling helps to reduce temperature rise, thereby improving the safety and efficiency of the equipment.

In operation, the B57238S0220M000 limits the inrush current to a predetermined safe level by acting as an impedance between the power supply and the load device. In doing so, it prevents the circuit from being overloaded and safeguards the system from the effects of a high inrush current. The device contains a thermal cutoff switch which acts as a safety feature in the event of an excessive inrush current. The thermal cutoff switch will activate if the current in the circuit is too high, thereby preventing damage to the circuit.

The B57238S0220M000 is an ideal solution for any application requiring reliable inrush current protection. It is compatible with most loads and voltage systems, and is easy to install. It can be used in a range of applications such as surge protection for switch-mode-power supplies, motors and other high-power devices. The device is designed to withstand severe surges and is well suited to industrial and commercial applications.

In conclusion, the B57238S0220M000 is a robust and efficient inrush current limiter designed for a wide variety of applications. The device is highly reliable and can be used in both AC and DC circuits. It helps to limit the inrush current while protecting the circuit from overload and offers reliable surge protection. It is highly recommended for both industrial and commercial applications.
