In modern life, every household is inseparable from electricity, and household appliances are also inseparable from the use of electricity. Every family has a very large demand for electricity, but when using electricity, it must be used safely, so as to ensure the safety of family members and themselves. A circuit breaker is an important circuit device in an electrical circuit and one of the most important safety mechanisms in a household circuit. This simple circuit arrangement shuts off power once the current flow in the house wiring is excessive until the fault is corrected. Without circuit breakers, household electricity would be very inconvenient. So what are the functions of circuit breakers? We can learn more about the role of circuit breakers from the following aspects.
The role of the circuit breaker is as follows:
The circuit breaker is also called the air switch. Its function is to cut off and connect the load circuit, as well as cut off the fault circuit, prevent the accident from expanding, and ensure safe operation. In the case of electrical overload or abnormal operation, if there is a fault, the circuit breaker will automatically open the switch to protect the electrical and circuit. In addition, there is a leakage protection device in the circuit breaker, which has the function of leakage protection.
Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overload or short circuit and undervoltage faults, the circuit breaker can automatically cut off the circuit. Its function is quite It is used in combination of fuse switch and overheating relay, and generally does not need to change parts after sectional fault current.
The above is the specific function of the circuit breaker. Through the above description, you can learn about the specific function of the circuit breaker in detail.
