Circuit Breakers

A circuit breaker is an electrical device that is designed for the protection of the electrical circuit against excessive currents and overloads. Circuit breakers are also used to protect against short circuits, which occur when a wire or other element shorts out. Circuit breakers can be found in every household on the electrical panel and are also used in many industrial settings.

IEG2-71191-8-V application field and working principle

The IEG2-71191-8-V is a type of circuit breaker that is designed for use in the residential and commercial sector. It is a three-phase circuit breaker that is capable of protecting individual circuits against excessive current, short circuits, and overload conditions. The IEG2-71191-8-V is designed to be easy to install and provides reliable protection in a wide variety of applications.

The IEG2-71191-8-V is designed to be used in combination with a compatible switchgear system and to have a breaker rating of 125 Amperes. It is constructed with a thermal-magnetic tripping mechanism to help protect against overloads and over current. It is also designed with a self-aligning feature for easy installation and a unique locking mechanism for added safety.

In operation, the breaker will monitor the current in the circuit. If the current exceeds the preset limit, the breaker will trip and open the circuit, removing the power and protecting the circuit from further damage. The breaker can be reset manually using the reset button on the breaker itself, or it can be reset remotely using a compatible switchgear system.

The IEG2-71191-8-V is designed to be used in combination with a compatible switchgear system in order to provide the highest level of protection. It is important to ensure that the circuit breaker is installed correctly and that it is compatible with the switchgear system that is being used. It is also important to ensure that the breaker rating is sufficient for the application, and that it is properly maintained in order to ensure its optimal performance.
