Circuit Breakers

A Circuit Breaker is a safety device that is used to protect an electrical circuit from damage caused by overload or short circuit. The IEG666-1REC4-30843-1-V is a type of circuit breaker specifically designed for medium-voltage applications. This article will discuss its application field and working principle.

Application Field

The IEG666-1REC4-30843-1-V circuit breaker is designed to protect medium voltage networks and installation from overvoltage, undervoltage, overcurrent, and short-circuits. It is suitable for a wide range of applications from industrial and utility applications to residential applications. It also has a wide range of rated switches, from 5A to 32A, ensuring that it is suitable for all medium voltage applications.

Working Principle

The IEG666-1REC4-30843-1-V circuit breaker works by automatically breaking the electrical circuit if it senses a current overload or a short circuit. This protects the electrical system from overloading and short circuit damage. When an overload occurs, the internal magnetic switch is triggered and the breaker trips. When the circuit is opened, the main contacts are broken, and the current reduces to zero. The circuit is then reclosed after the overload has been cleared. If a short circuit occurs, the breaker trips and the main contacts are opened. The short circuit current then dissipates and the breaker can then be reset once the short circuit has been cleared.

The IEG666-1REC4-30843-1-V circuit breaker is designed to provide reliable protection and is suitable for a wide range of applications. It is easy to install and easy to maintain, making it an ideal choice for all medium voltage applications.
