Circuit Breakers are an important part of a power system. They safely regulate the current flow and protect critical components from the devastating effects of electrical overloads and short circuits. The 299-3-1R-2911-9 Circuit Breaker is an industry staple, designed to handle medium voltage applications in a wide range of industries. This article will provide a brief overview of the 299-3-1R-2911-9 Circuit Breaker\'s application field and working principle.

Application Field

The 299-3-1R-2911-9 Circuit Breaker is designed for use in medium voltage panelboard or switchboard applications. This includes industrial, commercial, and domestic electric systems. It is capable of handling currents of up to 3,000 A and is designed for use in applications with an operating voltage of 5 kV to 35 kV. The breaker also features a reliable self-protection system, designed to ensure optimal performance in the toughest working environments.

Working Principle

The 299-3-1R-2911-9 Circuit Breaker is designed to function using a self-protection system. This system consists of a voltage sensing trip bar, a set of motor-operated mechanisms, and a set of overcurrent protection devices. When an overcurrent condition is detected, the trip bar triggers the opening of the motor-operated mechanisms, which then shut off the power to the circuit. The overcurrent protection devices then act as backups to ensure that any further current surges can be reliably shut off.

The 299-3-1R-2911-9 Circuit Breaker also features a voltage release system. This system is designed to protect the breaker from surges in voltage. It works by automatically releasing the contacts when an overvoltage condition is detected, thus preventing damage to the system. The voltage release system also helps the breaker respond effectively to short circuits and power outages.

The 299-3-1R-2911-9 Circuit Breaker is designed with safety in mind. It features a high-visibility indicator which helps identify a breaker that has tripped. Additionally, the breaker is designed to prevent the risk of shock. This is done by using insulated contacts and a special resistor which prevents electromagnetic interference. These features help to ensure the safety of users in any environment.

Conclusion

The 299-3-1R-2911-9 Circuit Breaker is a powerful, reliable, and safe device which is an essential component in medium voltage applications. Its self-protection system and voltage release system ensure optimal performance in the toughest environments, and its shock-preventing features keep users safe. It is a robust and reliable solution for any industrial, commercial, or domestic application.
