Inrush current limiters (ICL) are devices designed to limit the initial inrush of current caused by energizing a device. Electrical engineers use ICLs to protect circuits from large inrush currents caused by capacitors and inductors in a circuit. The SL15 2R508 is such an Inrush Current Limiter.

The SL15 2R508 offers superior current limiting characteristics in a compact form factor, allowing electrical engineers to include it even in the most space-constrained projects. This model is rated to operate from -55°C to +105°C and includes a self-reset feature for additional safety. The SL15 2R508 is designed to limit the inrush current to a maximum of 30 amps.

The working principle of the SL15 2R508 is based on Nonlinear Resistance (NLR) technology. The NLR technology creates a thermal resistance element between two electrical contacts, which will prevent an overload or short circuit. The contacts remain separated until the inrush current exceeds a specific limitation, producing an electrical arc between the contacts to ensure the current is limited to the maximum set point. As the inrush current falls below the limit point, the contacts separate again and the ICL is reset to its original position.

The practical application fields of the SL15 2R508 include power supplies, consumer electronics, and automotive systems. This model can be used in most applications that require current limiting, such as home appliances, battery chargers, lighting controls, solar inverters, uninterruptible power supplies, and industrial control systems. By using this model, electrical engineers can minimize the power losses due to inrush current and prevent overloading of their electrical systems.

In conclusion, the SL15 2R508 is a type of Inrush Current Limiter (ICL) which has a wide range of applications and is designed to limit inrush current to a maximum of 30 amps. Its working principle is based on Nonlinear Resistance (NLR) technology, which prevents an overload or short circuit by creating a thermal resistance element between two electrical contacts. The practical application fields of the SL15 2R508 include power supplies, consumer electronics, and automotive systems.
