Inrush Current Limiters (ICL) are devices used to reduce the amount of current that is permitted to enter an electrical system as it is switched on or connected to a power source. The SL15 2R507-B is a type of ICL which is widely used in the industry. This article will discuss the application field and working principle of the SL15 2R507-B.

Application fields: SL15 2R507-B is mainly used in the transformer industry. It is mostly used in the line reactors and auto-transformers which demand high reliability and safety, as well as in uninterruptible power supply (UPS) applications. Its use in transformer products such as control cubicles, transformers, boosters, line reactors, and auto-transformers ensures that the power supply to the product is stable and that it is protected against external power fluctuations.

Working principle:The SL15 2R507-B consists of two parts - a positive and a negative part. The positive part is the current-limiting resistor which limits the amount of current flowing into the circuit, while the negative part is a temperature-sensitive device which limits the amount of heat generated by the resistor. The negative part acts as a temperature switch which is triggered when the temperature of the resistor rises beyond the set threshold. When this happens, the switch is triggered and the current is reduced. This ensures that the current entering the circuit does not exceed the set limit.

The SL15 2R507-B is an effective current limiter that allows for a stable power supply to the transformer. It also provides protection against external power fluctuations and ensures that the transformer is not damaged by high currents. The current limiter is also used in other applications such as uninterruptible power supply (UPS) systems to protect against power surges.

The SL15 2R507-B is a reliable, cost-effective, and easy-to-use device which can be used in a variety of applications. These include transformers, line reactors, auto-transformers, control cubicles, and uninterruptible power supply (UPS) systems. It is an important component in ensuring the safety of transformer operations and is used to reduce the amount of current entering electrical systems.
