Circuit- breakers are regulatory devices for overcurrent protection: overloads and short circuits. Their function is to act when a fault is detected, that is to say, to cut off the electricity supply of the installation and allow its restoration when the anomaly has been solved.
According to the standards, the automatic circuit breaker is defined as the “mechanical connection device capable of establishing, supporting and interrupting currents in the normal conditions of the circuit, as well as of establishing, supporting for a certain time and interrupting currents in specified abnormal conditions of the circuit such as short-circuit”.
What are the basic parameters for the selection of the circuit breakers? How is it possible to classify them? Read the full article.
