Inrush Current Limiters (ICL) provide protection from current spikes (or inrush current) that occur when switches and contactors are used to load and/or isolate high current electrical circuits. ICLs are a critical part of modern electronics, as they can prevent damaging and costly damage to expensive electronics, motor controls, and interconnection systems. The MS22 50004-A is an example of such a device, providing a safe and reliable alternative to conventional limiting methods such as fuses, thyristor circuits, and spark gaps.

As its name implies, the MS22 50004-A is fitted with an inrush current limiter. The device is designed to limit the maximum current that can be drawn by the connected circuit, preventing short-term spikes that can damage components and cause premature failure. The limiting feature is made possible by a series of resistors, arranged in a specific pattern. The resistors are connected in series between the circuit load and ground, limiting the available current that can be drawn. In order to limit the amount of current drawn by the connected circuit, the MS22 50004-A features a thermal cut-out switch. This switch disconnects the load when the inrush current passes a predetermined limit, ensuring that no damage can occur.

The MS22 50004-A can be used in many applications, including lighting systems, power supplies, electric motors, and interconnection systems. It can also be installed in a variety of electronic devices, including computers, phones, and televisions. As the device is specifically designed to limit inrush currents, it can protect these devices against the harmful effects of high current spikes. By using an inrush current limiter, users can have peace of mind knowing that their electronics will not be damaged by unexpected power spikes.

The working principle of the MS22 50004-A is simple and straightforward. Initially, when the switch is turned on, current flows into the connected circuit. This is known as the transient, or inrush current. The resistors in the device limit the flow of current, controlling the maximum current that can be drawn. When the current reaches a certain level, the thermal cut-out switch opens, and the current is cut off. As a result, the connected circuit is protected from short-term surges that could cause damage.

Overall, the MS22 50004-A is a reliable and efficient inrush current limiter that can protect electronics from the damaging effects of power spikes. By providing a safe and cost-effective method of limiting inrush currents, the device ensures that electronics remain safe and operational. The device is a great choice for any application that requires protection from short-term power surges, and it can be easily installed in a variety of electronic devices.
