Circuit Breakers

Circuit breakers have been used in the form of electrical protection technology since the 19th century. Over the years, they have become an integral part of electrical systems and are responsible for safeguarding delicate electronic systems against dangerous electrical surges. In this article, we take a look at the 9129813200 application field and working principle of circuit breakers.

Application Field

Circuit breakers have a wide range of applications, infiltrating all aspects of our lives. From the lighting system in our homes, to the backup power generators in power plants and the power grids of entire cities, the use of circuit breakers is ubiquitous.

Circuit breakers are also used for operations with increased safety considerations. For instance, in the metallurgical industry, large and heavy machinery are used to operate in hazardous environments, such as high temperatures or exposure to combustible concentrations of gases or other pollutants. In such cases, the use of circuit breakers, as well as other electrical protection and control systems, is recommended in order to reduce the risk of human injury or destruction of valuable equipment.

Working Principle

A circuit breaker is essentially a mechanical switch that is designed to switch off in the case of an electrical surge. It consists of a movable contact arm and a stationary contact, which are usually connected to a heat-sensitive strip material. When an excessive electrical current is flowing through the circuit, the heat-sensitive material “trips”, causing the contact arm to shift and cutting off the flow of current.

The trigger mechanism of a circuit breaker is a temperature-sensitive device, usually housed inside its body. Once the temperature reaches a certain level (determined by the level of current running through the breaker), the trigger mechanism activates and shifts the contact arm, thereby switching off the electricity supply. The reset mechanism then needs to be actuated to reboot the breaker.

Modern circuit breakers come in two types – high voltage breakers and low voltage circuit breakers. Low voltage circuit breakers are generally used in home and office applications and are designed to detect and respond to overloads or short circuits in small electrical circuits. High voltage circuit breakers, on the other hand, are used in larger industrial applications, such as power grids and substations, and are designed to offer protection against more severe electrical faults.

Conclusion

The 9129813200 device is a vital component of all electrical systems. It is responsible for providing both electrical protection and control, helping to keep personnel and equipment safe from dangerous power surges or overloads. It is available in two types – low voltage and high voltage – allowing for usage in a range of applications. Understanding the working principle of the device helps users to use it more effectively.
