Inrush Current Limiters (ICL): MS22 75004-A Application Field and Working Principle

Inrush current limiters (ICLs) refer to devices that protect electrical components and systems from excessive, sudden current. This is a common issue that arises when appliances are turned on. ICLs provide reliable protection during starts for a wide range of applications, from electric, lighting, industrial applications to home appliances.The MS22 75004-A is a state-of-the-art inrush current limiter made by American manufacturer Veris Industries. This device is a fully-sealed, thermally protected, thermoplastic NEMA 4/IP66 rated device, designed to reduce inrush current when AC voltages are turned on. This particular ICL is featured in a variety of industries, like industrial and motor control, solar, HVAC, food transport, and medical.The MS22 75004-A has many features, among which an adjustable inrush current limit, LED indicators, external manual reset option, and various mounting styles. It can be easily mounted and separated from other devices using metal and plastic brackets. It also provides protection against dust, moisture, dirt, oil, and other contaminants.The MS22 75004-A is engineered to conform to UL, CSA, EN, CE, and other safety standards. It is designed to reduce or minimize the initial surge of current that occurs when a load is switched on. This device includes a precision time delay circuit, which delays the starting time, reducing the peak current at the start of the motor or transformer. Consequently, it reduces the motor or transformer life. This particular ICL works through a resistive element that limits the inrush current for a specified period of time when the load is switched on. It ultimately reduces the peak of the current waveform and the time period of the current waveform. A further benefit of this device is that it has a low quiescent power consumption (15 mW maximum), thus it has a negligible impact on the electrical system. Overall, the MS22 75004-A inrush current limiter is an advanced device that ensures maximum protection of electrical appliances from high inrush current, thus securing a longer lifetime of components and ensuring better energy efficiency. It is ideal for systems and components requiring durability, reliability, and safety.
