Inrush Current Limiters (ICL), also known as inrush current suppressors or inrush current limiters, are devices that limit inrush variance in electrical systems. The B57213P0470M351 is an example of such a device. These limiters are used in home and industrial applications where current control is necessary. They are used to protect sensitive equipment from power shocks and to limit the input current to a certain level in any given circuit.

In general, an Inrush Current Limiter contains a temperature-controlled resistor, or a thermistor, which is mounted in parallel with the load. When the power is turned on, the resistor catches the excessive inrush current, hence the name "inrush current limiter". The resistance value of the thermistor is chosen to limit the power to an appropriate level. After the power is turned on, the thermistor slowly reduces in resistance and the current rises slowly over time until it reaches its steady state.

The B57213P0470M351 inrush current limiter is a special type of thermistor that is designed to provide protection against inrush current in home, industrial, and automotive applications. This ICL has a wide range of features including a temperature coefficient of resistance, a high-voltage rating, and a low-temperature coefficient of resistance. The device is designed to limit the current to 4.7 A, making it suitable for applications with high inrush power requirements.

The B57213P0470M351 offers a one-time, time-limited period of high current in order to protect sensitive components from damage due to inrush current. Its thermistor is designed to be semiconductor-free to ensure that it is not vulnerable to power surge, and its temperature coefficient of resistance is designed to work with a wide range of temperatures.

In addition to ICLs, other device types are also available. These include MOVs (metal-oxide varistors), TVSs (transient voltage suppressors), fuses, and surge arresters. While these other types of protection may offer very good performance, an ICL is the most cost-effective and reliable protection available.

The B57213P0470M351 has numerous application fields. it can be used in appliances, electrical equipment, instrumentation, motors, power supplies, UPS systems, solar systems, as well as other high-current applications. It is used to limit damage to sensitive components and to ensure an optimal input current level in high-current applications.

In conclusion, the B57213P0470M351 is an important type of inrush current limiter that provides protection against high currents in home, industrial, and automotive applications. Its resistance is adjusted according to the temperature, providing an optimal level of current protection. This device is an indispensable part of any power system, and its numerous application fields make it an excellent choice for limiting inrush current and protecting sensitive components.
