Introduction

Circuit Breakers are an essential safety device in the electrical system. It protects the electrical equipment connected to the electrical circuit from damage caused by abnormal overcurrent. The circuit breaker consisting of 219-3-8625-22 is one of the circuit breakers used widely in power distribution systems. This article will discuss the application field and working principle of 219-3-8625-22 circuit breakers.

Application Field of 219-3-8625-22 Circuit Breakers

219-3-8625-22 circuit breakers are typically used in low-voltage distribution systems, such as those in residential, commercial and industrial buildings. It can be used in systems with an operating voltage ranging from 110-220 volts AC. They are most commonly used for the protection of lights, motors, appliances and electronic equipment in buildings.

Working Principle of 219-3-8625-22 Circuit Breakers

219-3-8625-22 circuit breakers follow the same basic working principle as any other type of circuit breaker. They are designed to detect when the current passing through the circuit is either too strong for the equipment being connected to the circuit, or when the power is not going to the right place. When this occurs, the circuit breaker will automatically cut off the power to the circuit, thus preventing any damage from occurring.The circuit breaker consists of a main switch, a control and trip unit, a contact system and an arc runner. The main switch is responsible for closing and opening the circuit. The contact system is comprised of stationary and movable contacts. The movable contact is connected to the control and trip unit. When an overload or short circuit occurs, the control and trip unit sense the current, and then trip the movable contact, thus breaking the circuit. The arc runner prevents the reestablishment of the arc when the circuit is opened through maintaining the contact\'s separation until the arc is extinguished.

Conclusion

In conclusion, 219-3-8625-22 circuit breakers are a type of commonly used circuit breakers. They are mainly used in low-voltage distribution systems. The working principle of these circuit breakers is fairly simple, in that they are designed to sense an abnormal overload or short circuit and automatically cut off the power. This is an essential safety device in the electrical systems, as it helps to protect equipment from damage caused by the abnormal current.
