A circuit breaker is an important device in a power system that performs the functions of both a switch and a fuse. The 2800840 is one of the most widely used circuit breakers available today. It is designed to provide reliable and safe protection for both residential and commercial applications.

The 2800840 is a UL listed, 2-pole circuit breaker with thermal-magnetic trip characteristics, suitable for residential and industrial applications. It features UL Type B trip current curves and is rated up to 30 amps at 120/240 volts AC. The breaker has a maximum interrupting capacity of 10,000 amps at 240 volts AC and 20,000 amps at 120 volts AC.

The 2800840 is designed to automatically detect any abnormal electrical environment in a power system, and rapidly disconnect the circuit to ensure the safety of personnel, equipment and the power system. Unlike an ordinary fuse, a circuit breaker is able to detect abnormal load conditions and automatically isolate the circuit from current flow, without having to be manually reset. This feature makes it ideal for residential and commercial applications.

The 2800840 circuit breaker works on the principle of thermal-magnetic tripping. The device uses a combination of two technologies to detect and trip the circuit - a thermal element, and a magnetic element. The thermal element is based on the Joule-Lenz Law which states that the current passing through a metallic conductor is proportional to its temperature. The breaker senses the temperature of the conductors and trips the circuit when the temperature exceeds a certain limit.

The magnetic element, on the other hand, uses an electromagnet to detect current flowing through the circuit. When the current passing through the circuit exceeds a certain limit, the electromagnet trips the circuit. The combination of these two technologies ensures that even low current faults can be detected, and is suitable for applications where there may be long pauses between overloads.

The 2800840 circuit breaker is a safe and reliable device for residential and commercial applications. It is able to detect both over current and over temperature conditions, and is able to trip the circuit before any damage occurs. This makes it an ideal choice for protection of valuable equipment, personnel, and the power system.
