Inrush Current Limiters (ICLs) are electronic devices that limit the amount of inrush current allowed into a circuit. While inrush current typically occurs at the initial power up of a circuit, it can also occur due to a sudden change in the supply voltage. In either case, this sudden rise in current can cause damage to the circuit due to electrical overload. ICLs, also known as surge protectors, prevent this overload by limiting the amount of current allowed into the circuit.

SL32 0R536 is one type of Inrush Current Limiter available on the market. SL32 0R536 consists of a solid-state contactor, rectifier diode bridge, and overvoltage protection relay that contains an LED indicator to detect and limit inrush and overcurrent. Its internal relay provides protection against voltage anomaly, opening it without passing any current through the contactor. It offers an adjustable current limiting range (CLR) and adjustable operating time range (OTR).

The wide range of applications for SL32 0R536 makes it a popular choice. Some of the usage include: air conditioning unit powered by electric motors, welding equipment, lighting systems, battery charging and other industrial equipment. The SL32 0R536 is suited for applications with voltage up to 750VIAC, current rating up to 50A and turn-off time up to 20ms.

The working principle of SL32 0R536 is based on the resistance-capacitance (RC) principle. When an large inrush current passes through the contactor, an internal RC network built into the device generates a counter-voltage which is used to reduce the main switch-off time. The internal relay is used to detect the voltage and provides overvoltage protection in case of overload, thus limiting the inrush current.

The particular working principle of SL32 0R536 is also determined by its contactor type and the rectifier diode bridge. This diode bridge allows current to flow only in the forward direction and prevents high voltages from passing the contactors and causing damage. Therefore, this current limiter can provide effective inrush current limiting for a wide range of applications.

Overall, SL32 0R536 is a reliable current limiter that can be used to prevent dangerous overcurrent or inrush current in a wide range of applications. Its adjustable current limiting range and adjustable operating time range make it ideal for applications with higher power demands. Its internal relay provides protection against voltage anomaly, and its contactor type and rectifier diode bridge ensure effective current limiting. It is an important part of any circuit’s protection.
