Circuit Breakers

The IEGBX1-36776-5-V is a type of circuit breaker that provides over-current and short-circuit protection. The device prevents damage to the electrical system and personnel by interrupting the path of an electrical current during an overload or short-circuit event. This article will discuss the application of the IEGBX1-36776-5-V and its working principle.

Application

The IEGBX1-36776-5-V is designed for both indoor and outdoor applications in medium voltage networks up to 24kV. It is most commonly used in distribution substations, proteciton systems, and control systems. The IEGBX1-36776-5-V has been specially designed for use in industrial environments where dust, dirt, and moisture are present. The device is constructed with a corrosion-resistant aluminum housing that offers improved thermal performance and weather protection.

Working Principle

The IEGBX1-36776-5-V circuit breaker operates on the principle of thermal overload protection. The device uses a bimetallic strip that is sensitive to electrical current. When an overload current passes through the strip, heat is generated and causes the strip to bend. This action moves a mechanical switch, which trips the device and interrupts the path of the electrical current. In the event of a short circuit, the same principle applies but in a much faster time period.

The device can also be equipped with an over-voltage protection system. This system is designed to automatically disconnect the power supply if the voltage exceeds a specified level. The IEGBX1-36776-5-V also features a current-limiting feature, which ensures that any faults that occur will be limited in magnitude.

Conclusion

The IEGBX1-36776-5-V is a robust, reliable circuit breaker that provides protection against over-current and short-circuit events. Its corrosion-resistant design means it can be used in both indoor and outdoor applications. The device operates on the principle of thermal overload protection and can be equipped with additional features, such as over-voltage protection and current-limiting, for extra protection.
