Circuit breakers are essential to the protection of electrical systems and the workplace. They protect components in the event of a catastrophic event, such as an overload of electrical power or a short circuit. In this article, we will discuss the application field and working principle of the APGN2-25984-1 circuit breaker.

The APGN2-25984-1 is a 3-pole, 24V AC/DC, 40A miniature circuit breaker, compliant with IEC/EN 60947-2 standards. Its tripping characteristics include the C type (3-5) for low current short circuits, B type (2-3) for medium current short circuits, and A type (1-2) for high current short circuits. It can also provide protection against overload, such as when a circuit is loaded beyond its rated value. This makes it ideal for use in medium voltage applications, such as residential, commercial, and industrial electrical systems.

The working principle of the APGN2-25984-1 circuit breaker is based on the thermal-magnetic tripping action. In short, when an overload or short circuit occurs, the trip motor will respond to the rapid increase in current. It then moves the trip lever, causing the terminals to be disconnected and the breaker to be manually reset. This process is known as thermal tripping, which is slower than the magnetic tripping process.

The APGN2-25984-1 circuit breaker is also equipped with a bypass switch which allows it to be used for maintenance purposes without interrupting power to the connected equipment. Moreover, the breaker is equipped with a test button which allows the user to test the trip characteristics and ensure that it is functioning correctly.

Overall, the APGN2-25984-1 circuit breaker is a high performance, compact, and durable circuit breaker that can be used in a wide range of applications. With its thermal-magnetic tripping action and bypass switch, it provides reliable protection against overload and short circuits, ensuring the safety of the connected equipment.
