Circuit breakers are electrical devices used to protect electrical systems from damage due to overloads, short circuits and power surges. The IEGX11-28170-1-V is a type of circuit breaker designed for use with medium-voltage power systems. This device features a contact system constructed out of pure silver, non-porous for greater contact integrity and increased service life. Its modular design allows for easy assembly and flexible operation. In this article, we will discuss the application field and working principle of the IEGX11-28170-1-V.

Application Field

The IEGX11-28170-1-V is designed for use in medium-voltage power systems, such as those in residential and commercial applications. It can be used in both indoor and outdoor applications, and its modular design allows it to easily fit into any standard electrical enclosure. The IEGX11-28170-1-V is suitable for both AC and DC applications, and can be used with both single- and three-phase systems.

Working Principle

The IEGX11-28170-1-V is designed to trip in the presence of an overload, short circuit or power surge. It does this by automatically opening the circuit when the current exceeds the breaker’s threshold. This is done by the breaker’s contact system, which consists of a pure silver trip contact connected to the breaker’s trip coil. The trip coil is connected to an electromagnet that, when energized, draws the trip contact and breaks the electrical circuit. The trip contact then returns to its original position when the power is switched off.

The IEGX11-28170-1-V can also be used in manual reset mode, in which the circuit is closed after a manual reset switch is pressed and the trip contact is released. This allows the user to determine when it is safe to close the circuit, ensuring the protection of the electrical system.

In addition, the IEGX11-28170-1-V features a series of indicators that alert the user of the breaker’s status. These include a red LED indicating tripped, a green LED indicating closed, and a yellow LED indicating manual reset mode. These indicators provide essential information that helps the user ensure the safety of their electrical system.

Conclusion

The IEGX11-28170-1-V is an essential component for protecting any medium-voltage power system, and its modular design allows for easy installation and flexible operation. Its pure silver contact system ensures integrity and service life, and its LED indicators provide essential information on the status of the circuit. With its reliable performance and intuitive design, the IEGX11-28170-1-V is an ideal choice for any medium-voltage power system.
