Circuit Breakers: 991250 Application Field and Working Principle

A circuit breaker is an electrical component that controls and monitors the flow of electrical current in a circuit. The 991250 circuit breaker is a two-pole unit that mounts easily onto DIN-Rail mounting and is particularly suited for applications in the range of 480VAC/277VAC. It offers superior protection and reliability for challenging applications and is available in a range of current ratings from 10A to 50A.

Applications of the 991250 Circuit Breaker

The 991250 circuit breaker is suitable for a wide range of applications in commercial and industrial settings. For example, it is suitable for use as a branch circuit breaker in commercial and industrial buildings, as a motor circuit breaker in machine installations, as a protection breaker for pumps, transformers, and motors, as well as for a range of lighting and heating applications.This circuit breaker is also suitable for use in hazardous areas, such as oil and gas plants, where it can provide safe, reliable power distribution. It is also well suited for use in industrial and offshore applications where it provides reliable protection from short circuits and overloads.

Working Principle of the 991250 Circuit Breaker

The 991250 circuit breaker utilizes an electromagnet, housed in a metal casing, which activates the circuit breaker when an excessive current is detected. The electromagnet consists of an iron core, wrapped with a coil of insulated wire. When a current overload occurs, the electromagnet is activated and a contact is opened, interrupting the circuit and preventing further damage.The electromagnet activates when the current overload exceeds the trip threshold current, which is generally set to approximately 150A. In order to reset the breaker, an operator must reset the trip current to a level below the trip threshold, which can be accomplished by using a small manual wheel.

Advantages of the 991250 Circuit Breaker

The 991250 circuit breaker has numerous advantages over traditional fuses and circuit breakers. It is cost-effective, easy to install, and offers superior protection from short circuits and overloads. It is also designed to provide a high degree of safety and reliability, as well as a wide range of current ratings. Additionally, it can be used in hazardous areas, where it provides reliable power distribution and protection from short circuits.

Conclusion

The 991250 circuit breaker is a two-pole device designed for use in commercial, industrial, and hazardous areas. It is easy to install and offers superior protection from short circuits and overloads. It is also cost-effective and has a wide range of current ratings. It is well suited for a range of applications, including branch circuit breakers, motor circuit breakers, transformers, pumps, and lighting and heating applications.
