Inrush Current Limiters (ICL) are self–actuating electronic components that minimize peak current drawn by large capacitive loads when powering a system. ICLs work by limiting the inrush current to a safe level. In other words, ICLs limit the flow of electrical current to protect any connected components or circuitry from an overabundance of current.

The SL12 1R010-B is an inexpensive general-purpose ICL designed for limiting inrush current up to 10 Amps. The SL12 1R010-B is a thermally activated device that transitions from high impedance to low impedance state. Its high current limit threshold is precisely determined by its internal thermal mechanism and design. Once the set current threshold is exceeded, the device immediately becomes temperaturesensitive and reacts by switching from low to high impedance in a matter of milliseconds.

The SL12 1R010-B is designed to provide a cost-efficient solution to reducing peak inrush current for the most demanding applications. Its thermally activated switch helps it automatically transition from a low to high impedance state when the current threshold has been exceeded. Although the SL12 1R010-B is designed to handle a wide range of current levels, it is best used for capacitive inrush current levels below 10 Amps.

The SL12 1R010-B is ideally suited for applications such as power supply start-up in numerous critical circuits, capacitor charging, and voltage transformer applications. The temperature-sensitive behavior of the SL12 1R010-B prevents overcurrents while allowing for smooth and rapid switch-on of secure load selections and protecting ultimate load damage in the course of a fault or erroneous wiring conditions.

The SL12 1R010-B is designed to prevent device overload and damage due to large start-up currents. To accomplish this, the SL12 1R010-B monitors the current flowing through its contacts. When the current reaches the set limit, the device quickly switches to a high impedance state and interrupts the current flow. The SL12 1R010-B acts as an electrical current limiter, which can be used to protect circuit components from overcurrents by limiting the current to a predetermined safe level.

The SL12 1R010-B is an effective and reliable inrush current limiter that provides reliable overcurrent protection. By limiting the current inrush to a safe level, the SL12 1R010-B can help ensure the safe operation of power supplies and other critical circuits. By protecting the system from overcurrents, the SL12 1R010-B can help increase the life of the system components and ensure reliable operation.
