Electronic molded case circuit breaker rated limit short-circuit breaking capacity Icu: circuit breaker has two breaking capacity index values: rated limit short-circuit breaking capacity ICU and rated short-circuit breaking capacity in working integrated circuit chip. As a characteristic parameter, ICS is not only a simple consideration of the breaking capacity of the circuit breaker, but also a breaking index value, in other words, everything can work normally after several times of short circuit common faults are destroyed.

With the advent of the Internet of Things, whether it is industrial production or daily life, the quality of the power supply system of the power supply system has been clearly put forward more and more specifications. This stipulates that the power supply and distribution system has a higher level of automation technology and intelligent level

Universal circuit breakers, also known as low-voltage circuit breakers, can also be used to manufacture and block load circuits, and can also manipulate motors that are not easy to run often. This is also the total amount of loss of the knife switch, electrical components or overcurrent relay pressure controller, and the role of undervoltage protection distribution network as an anti-cracking heat relay is a major one.
