Circuit Breakers

Circuit breakers are devices for controlling the flow of electricity in a system. They are essential to ensure that electricity is safe to use and that the system is not damaged by power surges or other potentially dangerous conditions. Circuit breakers come in many different forms and models, and they can be applied either to protect a single circuit or several. In this article, we will focus on one type of circuit breaker, the 8340-T110-K1T2-ALH126-2A, and the purpose and working principle of this breaker.

Application Field

The 8340-T110-K1T2-ALH126-2A is a high-amperage circuit breaker suitable for installation on industrial systems and infrastructures, such as electrical utilities and power distribution networks, as well as commercial and residential buildings and facilities. The breaker is equipped with an adjustable thermal trip, which allows for customization of the settings to ensure optimal protection to the specific application.

Working Principle

The working principle of the 8340-T110-K1T2-ALH126-2A breaker is straightforward: when an overcurrent or overload occurs on the circuit, the bimetallic strip inside the breaker activates, causing the circuit to be interrupted. The bi-metallic strip is made of two dissimilar metals, usually copper and zinc, which expand or contract at different rates when the temperature changes. This differential expansion is used to close and open the breaker switch contacts, stopping the flow of electricity.

When the current exceeds the values set by the adjustable thermal trip, the metal strip expands faster, opening the contacts and breaking the circuit. After the overload is over, the bi-metallic strip cools quickly and contracts, restoring the contacts and returning the breaker to an operational state.

Features and Benefits

The 8340-T110-K1T2-ALH126-2A breaker is designed to provide maximum safety and functionality. It features an adjustable thermal trip and a manual reset switch that allows the current value to be tested and adjusted. Additionally, the breaker’s housing is designed to prevent dust, debris and other foreign matter from entering and interrupting the circuit. Moreover, the breaker is designed to integrate with the specific application and its environment, minimizing noise and ensuring high reliability.

The breaker is also designed to be easy to install, maintain and service. The breaker is supplied with mounting brackets and terminal lugs, eliminating the need for separate fixtures. Additionally, the breaker is equipped with a test button and adjustable trip level, for quick and easy testing and adjustment.

Conclusion

The 8340-T110-K1T2-ALH126-2A is a high-amperage circuit breaker suitable for installation in industrial, commercial and residential facilities. It is equipped with an adjustable thermal trip, bimetallic strip, manual reset switch and other features to ensure reliable and safe protection of the system. Additionally, the breaker is easy to install, maintain and service, making it a great choice for any application.
