Circuit breakers are essential components of any electrical system. They provide protection against short circuits, overcurrent, and overloads, and help prevent damage to electrical components and circuits. The 219-3-8625-17 is a type of circuit breaker designed for a variety of applications. This article will discuss its application field and working principle.

Application Field

The 219-3-8625-17 circuit breaker is typically used in applications where the current levels do not exceed 440V AC. It has been designed to provide a reliable and safe operating platform for a variety of applications, such as ac- and dc-driven equipment, breaker panels, and other industrial machines.

It is designed to work in both indoor and outdoor installations. Due to its rugged design, it can work reliably in harsh environments, such as high temperatures and vibration. It is UL listed, and thus can be used in areas where UL approval is required. Furthermore, it complies with the relevant industry standards, which makes it suitable for use in a variety of applications.

Working Principle

The 219-3-8625-17 circuit breaker is a current limiting device. It works by detecting abnormal amounts of current flowing through a circuit and breaking the circuit when a predetermined threshold is exceeded. The breaker uses a thermal-magnetic tripping mechanism, and the tripping characteristics can be adjusted using a calibration process.

When the current in the circuit exceeds the preset threshold, the temperature of the internal components increases. This causes the bimetallic sheet in the breaker to expand and activate a tripping mechanism, thereby breaking the circuit. Once the current has been reduced, the bimetallic sheet will cool and reset the circuit breaker.

In addition, the circuit breaker also has an overcurrent protection feature. This feature works by allowing a certain level of current to flow while simultaneously constantly monitoring the current level. If the level exceeds the preset threshold, an alarm is triggered and the breaker trips.

Conclusion

The 219-3-8625-17 circuit breaker is a reliable and powerful current-limiting device. It is designed for medium to low-voltage applications, and is suitable for both indoor and outdoor use. Additionally, it is UL-certified and compliant with relevant industry standards. It uses a thermal-magnetic tripping mechanism to detect abnormal currents, and also has an overcurrent protection feature.
