Circuit breakers are devices that protect electrical circuits and equipment against excess current. The APL11-2REC5-9808-1 circuit breaker is one of the most popular types of circuit breakers used in the commercial, industrial, and residential markets. This particular breaker is an automatic, single-pole, two-position type with a current rating up to 15 amperes.

The main application of an APL11-2REC5-9808-1 circuit breaker is to protect wiring circuits from overcurrent damage, which can be caused by too much load (such as a short circuit), or by failures in the circuit protection system itself. It is also used to protect devices such as switches, relays, contactors, and motors from excessive electrical shock. In general, circuit breakers provide greater protection for electrical circuits than fuses, since they are quicker to sense and trip during a fault condition.

The working principle of an APL11-2REC5-9808-1 circuit breaker is simple. It consists of a metal strip connected to two separate contacts. When a pre-determined current flows through the breaker, the strip--called the bimetal--deflects, causing the contacts to move away from each other. This is the trip action that stops the flow of electricity and prevents further damage from occurring.

When the breaker is reset, the contacts move back together, allowing the electrical current to flow freely. This reset action is also triggered by the bimetal. However, the bimetal must be cooled down before it can return to its original position, otherwise, it will remain tripped. This is why APL11-2REC5-9808-1 circuit breakers are also well-suited for applications where it is necessary to prevent the current from being immediately re-established.

The advantages of APL11-2REC5-9808-1 circuit breakers include their ability to protect wiring circuits, switchgear, and other equipment from overcurrent damage, as well as their superior ability to sense and trip during a fault condition. They are also relatively easy to install and maintain, and their reset feature prevents the immediate restoration of current after a trip. Additionally, these breakers are highly reliable and can be used in a wide range of applications.
