Circuit Breakers are a type of safety device used to protect electrical components from electrical surges. The APG1-34931-4 is an example of a circuit breaker, with a wide variety of applications and functioning principles.

The main function of circuit breakers is to protect electrical components and circuit breakers from excessive or dangerous levels of power. When too much power is applied to a circuit, the breaker will trip, meaning it will open in order to disconnect the circuit from the power. This prevents the circuit from becoming overloaded and causing permanent damage or present danger.

The APG1-34931-4 is one example of a circuit breaker, specifically designed for medium-voltage applications, for power networks up to 24 kV. This circuit breaker has a rated breaking capacity of 40 kA and is IP54-rated, meaning it is dust- and water-protected, allowing for outdoor installation in industrial areas. It operates using a single-phase fully encapsulated hydraulic magnet drive mechanism with no need for external energy, making it an efficient and reliable safety device.

The APG1-34931-4 can be used for a variety of applications, from residential and industrial electrical supplies to complex networks in power stations and heavy industry. Due to its design, it can also be used for bridge control, building automation systems, arc suppression, power distribution, and other such areas.

In addition, the APG1-34931-4 has a fast operation time, selecting in just 200 ms and breaking in just 0.07 ms. Its adjustable pick-up current ensures that it is able to effectively trip off on the proper current, the adjustable interface prevents problems associated with overcurrent or thermal blowouts, and its adjustable delay allows for adjustable time delays for more precise and accurate protection.

The APG1-34931-4\'s working principle is simple; when the current exceeds the set level, the breaker will trip and cut off the power to the circuit. In order to reset the circuit, the reset handle must be manually triggered. This ensures that all circuits are safe and will not restart until the reset handle has been used.

Overall, the APG1-34931-4 is an efficient and reliable medium-voltage circuit breaker, with a variety of applications and an easy-to-understand working principle. Its adjustable parameters make it easier to use and tailored to the individual’s needs, and its fast operation time ensures that the protection is there when you need it most.
