Inrush Current Limiters (ICL) remain an important factor in cost-effectively protecting electrical circuits, and the need for them has grown significantly in recent years as electrical loads have increased alongside technological advancements. The SG110 is a type of ICL, designed to protect against sudden surge of current that can happen when switching on high-powered electrical circuits. It works by absorbing the high level of current and dissipating it over a longer period, allowing the circuit to be switched on without causing damage.

ICLs, or Inrush Current Limiters, are designed to control the inrush current of a circuit, thus preventing it from exceeding its load current when the main supply is switched on. In other words, their purpose is to limit the amount of current that flows into the main supply when the power is switched on, thereby avoiding damage to the circuit and the system. The SG110 is one such ICL and is designed to reduce high first inrush currents of up to 6,000 A. The operating principle of the SG110 is to absorb the high current flow and dissipate it to the load within a controlled time period.

The SG110 is a type of resistive current limiter, which means that it uses a resistive element to control the flow of current and reduce inrush currents. Its resistive element is made up of a carbon graphite material with high electrical and thermal conductivity and low electrical resistivity. The carbon graphite layer can absorb a certain amount of energy, thereby limiting the peak current that flows into the circuit. Thanks to the unique design of the SG110, it allows for flexibility in controlling and dispersing the current as required.

The SG110 can be used in a wide variety of applications and can be adapted to a variety of different electrical loading conditions. For example, it is suitable for controlling the start-up current in motor-driven applications, as well as for current regulation and protection when switching on UPS systems. It is also suitable for usage in the converters and circuit breakers of power supply units.

In addition to its versatility in terms of application, the SG110 also offers a safe and cost-effective solution for the inrush current problem. It is designed to withstand up to 50,000 switching operations without sacrificing its performance. This ensures that it is able to stand up to long-term overloads, all while offering cost-savings when compared to traditional current limiters.

In summary, the SG110 is a type of Inrush Current Limiter which is designed to help protect electrical circuits from damage caused by sudden surges in current. It works by absorbing and dissipating the high levels of current over a longer period of time, allowing the circuit to safely be switched on without causing damage. The SG110 is suitable for use in a number of different applications, offering a cost-effective solution that is safe, reliable and durable over long-term.
