Inrush current limiters (ICL) are devices designed to limit the inrush current of electrical systems during its power-up. These limiters are commonly seen in consumer, commercial and industrial applications where non-linear loads or air-condition elements are activated. The B57235S0809M000 is an example of an ICL, designed to offer reliable protection against inrush current under frequent start-up without sacrificing performance or energy efficiency.

The B57235S0809M000 is a type of ICL which is made of characteristics of both NTC (negative-temperature coefficient) thermistors and MOV (metal-oxide-varistor) elements. A MOV is a component that is designed to shunt away extremely high short-term spikes, while an NTC thermistor is used to regulate the extreme temperature variations associated with these spikes.

The working principle of the B57235S0809M000 is simple. When the main power switch is turned on, the thermistor regulates the device’s operating temperature, which in turn allows the MOV to shunt away the inrush current. Its resistance level is then restored to a nominal value after the transient spike passes. As the system continues to operate, the MOV also limits the voltage deviation from peak to peak to ensure a steady supply of energy.

The B57235S0809M000 is mainly used in power supply units, industrial controls, low voltage installations, lighting systems, IT equipment, HVAC systems, and automotive applications. It is designed to protect a wide range of electrical and electronic systems from the instant surge caused by the loading of non-linear elements. This ICL is also capable of suppressing electromagnetic interference (EMI) and radio-frequency interference (RFI) for improved system operation.

The advantages of using the B57235S0809M000 as an ICL are numerous. Its simple design offers reliable protection with minimal power consumption, which makes it energy-efficient. Furthermore, the device is designed with a high cycle life in mind, with a peak current rating of up to 350A and a voltage rating of up to 500V. The device also offers over-temperature protection with a compact and lightweight form factor.

The B57235S0809M000 is a highly reliable and efficient inrush current limiter for various electrical systems. It offers protection against high inrush current and over-voltage transient events, while also suppressing EMI for improved system operation. Its energy-efficient and lightweight design, combined with its high current and voltage ratings, make it an ideal choice for a wide range of applications.
