Circuit Breakers

A circuit breaker is a type of electrical device used to prevent an overload from damaging a power system. It works by cutting off the power, allowing the system to cool down, and then restoring it once the overload has been removed. The 219-4-6388-099 application field and working principle is designed for insulation and overload protection in single level or two-level distribution boards with six to sixty-four poles. The protection device contains overcurrent release, and the voltage release works depend on the incoming voltage.

Application Field

The 219-4-6388-099 is suitable for indoor use, and is designed to protect single-phase and two-phase power systems from overloads, short circuits, and insulation faults. It is also used in industrial and agricultural power systems, power plants, and power grids. Its protection range is rated current 25A to 125A.

Working Principle

The working principle of the 219-4-6388-099 can be divided into four stages. The first stage is the Normal Working State. In this state, the breaker is in its "on" position and current is flowing through the system. The second stage is the Overload Protection State. When the current reaches a certain level, the breaker trips and cuts off the power supply to the system. The third stage is the Restoration State. After the current has gone down to a safe level, the breaker can be restored to the Normal Working State by pressing the reset button. The fourth stage is the Short Circuit Protection State. When the current exceeds the set rating, the breaker trips and shuts off power to the system immediately.

Advantages

The 219-4-6388-099 has a number of advantages over traditional fuse-boxes and breakers. Firstly, it can be used in places where other types of switches or control boxes are not suitable, such as in power plants and power grids. Secondly, it is very reliable and has a long service life. Thirdly, it is also very economical since it reduces the downtime and losses caused by excessive current or short circuit. Lastly, it is self-resetting, so there is no need to manually reset the breaker after each trip.

Conclusion

The 219-4-6388-099 circuit breaker is a reliable and economical solution for protection against overloading, short-circuiting, and insulation faults in single level or two-level distribution boards with six to sixty-four poles. It follows the working principle of four stages consisting of normal working state, overload protection state, restoration state, and short circuit protection state. It has a number of advantages over traditional fuse-boxes and breakers, including reliability, cost effectiveness, and self-resetting capability. Therefore, it is a suitable protection device for a variety of power systems.
