Circuit breaker is a kind of automatic switching device which is mainly used in power system to complete the circuit between its two poles, make or break the circuit in a very short time, and complete the power supply together with some other ancillary equipment. 219-4-6388-171 is one type of circuit breaker. It combines the technology and application fields of the whole circuit breaker family. Its application field is extremely wide, and its working principle is also very reliable.

In terms of its application fields, 219-4-6388-171 is widely used in many fields. In general, it is mainly used for various low-voltage circuit connections, power distribution networks, power supply systems, and main power supply and other power systems in modern industrial and mining enterprises. With the rapid development of science and technology, it can also be used in automatic protection systems such as industrial control, UPS uninterruptible power supplies and other occasions.

219-4-6388-171 has a particularly high reliability and uses the principle of thermocoupling to complete the highest switching action in the shortest possible time. The device includes two parts. The new part is the solid state switch and the power part is the existing switch. When the current reaches a set value, the power switch is quickly opened by using the energy produced by the internal heating of the current itself to open the solid-state switch. Thus, it can effectively protect the circuit from damage due to overheating. In addition, the switch can be reseted to return to the on-state after the event and after the fault is eliminated.

In summary, 219-4-6388-171 is a kind of circuit breaker. Its application field is wide and its working principle is reliable. It is mainly used for low voltage circuit connection, power distribution network, power supply system and others in industrial and mining enterprises. The circuit breaker uses the principle of thermocoupling to help open the solid state switch efficiently, and protect the circuit from damage due to overheating.
