Circuit breakers are one of the most important components of an electrical system. They provide protection to the electrical system and the people who use it. The IELHK111-30299-272-V is a high-voltage circuit breaker designed for industrial applications. It is a cost-effective solution for protecting high-voltage circuits from over-current or short-circuit overloads.

The IELHK111-30299-272-V is a two-pole circuit breaker with a voltage range of 1000V to 3600V. It can be used for applications that require high current rating, up to 50kA. The contacts are arranged in a conventional three-pole arrangement for easy maintenance. They are designed to break or make an electrical connection when a current overload occurs. This helps to prevent electrical accidents and protect the equipment and personnel from any danger.

The IELHK111-30299-272-V circuit breaker has two operating modes, make before break and break before make. In make before break mode, the contacts close before opening and are therefore used to start motors or other electrical devices that require an electrical supply to be initiated. In break before make mode, the contacts open before closing and are used to stop running motors or other electrical devices.

The IELHK111-30299-272-V uses a mechanically operated moving contact arm inside a vacuum chamber. The chamber is filled with a high-pressure gas, such as SF-6 gas. When the contacts are closed, an electrical arc is formed between them and the gas is ionized. This ionization forms a spark, which instantly extinguishes the arc. The moving arm then lowers and the contacts break the current, thus helping to protect the electrical system from damage caused by an overload. The contacts then reset automatically after a predetermined amount of time.

The IELHK111-30299-272-V circuit breaker is designed for use in industrial applications such as power plants, substations, factories, and other large-scale industrial operations. Its main purpose is to protect the electrical system from overcurrent or short-circuit overloads. It is also certified to UL, CCC, and CE standards, which ensure it meets safety standards for use in hazardous areas. As such, it is a reliable and cost-effective solution for a wide range of industrial applications.

The IELHK111-30299-272-V is a reliable, cost-effective circuit breaker that provides high-voltage protection from short-circuit or over-current overloads. It has two operating modes and is designed for use in industrial applications. The certified safety standards make it an ideal solution for a wide range of industrial applications where high-voltage protection is required.
