Circuit breakers are electrical devices designed to protect electrical installations against long-term damage and short-term overvoltage. There are different types of circuit breakers available, including APG1-1REC2-2916-25.

The APG1-1REC2-2916-25 circuit breaker features a high breaking capacity of up to 25kA and is suitable for protecting electrical installations in both industrial and residential areas. It is designed to trip at overvoltage levels of 1.4 times the rated voltage, preventing damage to connected electrical equipment. It also features a wide range of adjustable settings for current tripping and resetting capabilities.

The APG1-1REC2-2916-25 is also designed with a modular design to allow for easy installation and maintenance. It includes a built-in alarm to inform personnel in case of an overvoltage event. Additionally, it has two different types of handle extensions, allowing it to be used in different locations without requiring any additional installation.

The working principle of the APG1-1REC2-2916-25 circuit breaker is based on an electromechanical mechanism. When a short-term overvoltage occurs, the breaker trips the overvoltage device and interrupts the power supply to the electrical system. The overvoltage device consists of an internal comparator, a permanent magnet, and a contactor.

When an overvoltage occurs, the internal comparator measures the voltage level and tells the contactor to switch the power off. The contactor then moves the permanent magnet to the “on” position, which pulls the contactor open and the power to the electrical system is interrupted. The breaker then needs to be manually reset to restore the power supply.

In addition to providing protection against overvoltage, circuit breakers such as the APG1-1REC2-2916-25 can also be used to protect electrical systems from other types of damage, such as lightning strikes or power surges. They can be used in a variety of applications, such as residential and commercial buildings, industrial and manufacturing plants, ships, and submarines.

In summary, the APG1-1REC2-2916-25 is an advanced circuit breaker designed to protect electrical installations against overvoltage. It features a high breaking capacity of 25kA, a wide range of adjustable settings, a modular design, a built-in alarm, and two different types of handle extensions. Its working principle is based on an electromechanical mechanism, which allows it to be used in different applications for protection against overvoltage and other types of damage.
