Inrush current limiters (ICLs) are devices that are designed to prevent large, damaging surges of electricity that can occur when power is applied to an electrical system. The ST20010B is an ICL that serves to protect electrical equipment from inrush current. In this article, we will look at the application field and working principle of the ST20010B.

The ST20010B is designed for high-voltage switchgear installations, typically from 18kV to 40.5kV. It is best used in environment where a peak inrush current of up to 3,500 Amps could occur. The ST20010B is a reliable device to prevent the damage that these large electrical surges can cause. Many of the components are silicone filled and come in a corrosion resistant stainless steel design for greater reliability and durability.

The working principle of the ST20010B is relatively simple. When power is applied to an electrical system, it can cause a large surge of electricity. This is known as an inrush current. The purpose of the ST20010B is to limit this inrush current by providing a "soft start" to the system. The ICL does this by creating a protected space around the system, which is filled with negative ions. These negative ions create an electrical barrier that blocks the inrush current from entering, thereby limiting the current and preventing damage to the system.

The ST20010B is a reliable and cost effective way to protect electrical systems from inrush currents and the damage they cause. The device is easy to install and provides a long lasting solution to the problem of inrush current. The device is highly reliable and has proven to be effective in protecting systems even in the harshest environmental conditions.

In summary, the ST20010B is a reliable and cost effective ICL designed to protect electrical equipment from inrush current. The device is designed for high-voltage switchgear and can withstand peak inrush currents of up to 3,500 Amps. Its working principle involves creating a protective space of negative ions around the system to block the inrush current from entering. The device is easy to install and provides a long lasting solution to the problem of inrush current.
