Circuit breakers are electrical devices that are designed and installed in electrical systems or circuits to protect them from damage due to overcurrent, overload, short-circuit, and ground fault conditions. The IELHK111-1-62-60.0-ABK-01-V circuit breaker is a type of low-voltage sulfur hexafluoride (SF6) system circuit breaker. It is used for protection of high-voltage electrical systems, from transmission lines, distribution lines, and low-voltage installations.

The IELHK111 circuit breaker is a type of metal-enclosed, vacuum-operated, arc-resistant, instrument-grade circuit breaker. It is designed to allow safe operation under normal conditions and provide protection for the system in the event of abnormal conditions like overloads and short-circuits.

The working principle of IELHK111 circuit breaker is based on the principle of air gap interruption. It uses a vacuum interrupter to break the circuit. The vacuum interrupter consists of two electrodes that are separated by an air gap. When the rated current passes through the electrodes, the air gap will create an arc and thus create an electrical interruption.

The IELHK111 is also equipped with a monitoring system that constantly measures the current and voltage in the circuit. The monitoring system is connected to the circuit breaker and enables it to detect any fault current and cut off the power supply in time to prevent any damages to the circuits.

In addition, it also has an arc-extinguishing device. This device is designed to extinguish any arc that may occur in the circuit due to an overload or short-circuit. This is done by using a gas operated burst that is connected to the vacuum interrupter. The burst will be activated when the current flow becomes too high or when the voltage in the circuit exceeds the set limits.

The IELHK111 circuit breaker is suitable for high-voltage transmission and distribution lines, as well as for residential and commercial installations. It is an efficient and reliable device that can be used to protect circuits from damage due to overcurrent, overload, short-circuit, and ground fault conditions. Additionally, it can be used as a master switch to disconnect the power in the event of an emergency.
