Circuit breakers are used as important components in electrical circuits, especially in conditions that require over-current protection. They are used in almost all electrical systems ranging from small residential applications to large power industrial plants. The IEGS66-27187-4-V Circuit Breaker is a new type of circuit breaker that is designed for medium to high voltage power systems. In this article, the application field and working principle of IEGS66-27187-4-V circuit breaker will be discussed.

The IEGS66-27187-4-V circuit breaker can be used in medium to high voltage power systems, such as power transmission lines, power distribution networks, and substation applications. It is designed for systems that require high current ratings, high short circuit ratings, and a variety of operating conditions. The circuit breaker has a voltage range of 7.2kV to 24kV, with a current rating of 630A and short circuit rating of 25kA. The device also has adjustable trip settings, short-time pick-up, adjustable ground fault settings, and a variety of current carry, overload, and short circuit protection features.

The working principle of IEGS66-27187-4-V circuit breaker consists of three stages. During the first stage, the circuit breaker detects a fault in the system, such as an overload or short circuit condition. When the fault is detected, the circuit breaker trips, transferring the current load to an external circuit. During the second stage, the device quickly shuts off the power supply to isolate the fault from the system. Finally, the circuit breaker will reset itself after the condition has cleared and reset, allowing normal operation to resume.

The IEGS66-27187-4-V circuit breaker is an important device in high voltage power systems. It is designed to provide reliable and efficient operation, thanks to its adjustable trip settings, short-time pick-up, adjustable ground fault settings, and a variety of current carry, overload, and short circuit protection features. The device is designed for applications that require high current ratings, high short circuit ratings, and various operating conditions.
