Circuit breakers are an essential component in any electrical application. In order to protect the user from the potential risks associated with high-voltage electricity, it is important that circuit breakers be able to detect and cut off electricity in the event of an overload or short circuit. The LEG66-38879-1-V is an example of such a breaker, and this article will discuss its application field and working principle.

The LEG66-38879-1-V is classified as an AC/DC 690V circuit breaker. This type of breaker is most commonly used in high-energy industrial applications. Its 690V rating makes it suitable for the majority of larger-scale industrial needs. This includes applications such as electric motors, large-scale pumps, transformers, and generators.

Apart from its 690V rating, the LEG66-38879-1-V also has an internal capacity of 100A. This allows it to handle large amounts of electricity at once without becoming overloaded or damaging itself. Additionally, the LEG66-38879-1-V has been designed for high speed switching. This means it is able to detect and cut off electricity within a fraction of a second, allowing it to protect the user from a potentially hazardous situation.

When it comes to the working principle of the LEG66-38879-1-V, it is relatively simple. When the current running through it exceeds its maximum capacity, the breaker detects this and opens a mechanical trip mechanism. This instantly cuts off the electricity and prevents any further current from being transmitted. The resulting interruption of power supply is enough to instantly shut down any equipment connected to the circuit breaker.

In conclusion, the LEG66-38879-1-V is a highly effective 690V circuit breaker which is suitable for both AC and DC applications. Its high internal capacity and fast switching time make it ideal for high-energy industrial applications, such as electric motors, pumps, transformers, and generators. Furthermore, the LEG66-38879-1-V works on a simple principle whereby it detects an overload or short circuit and trips a mechanical trip mechanism which instantly cuts off the electricity.
