The role of circuit breakers and how to choose
Speaking of circuit breakers, I believe everyone has heard of it. Circuit breakers are actually what people often call air switches. In recent years, air switches have become an indispensable device in the home. So, what is the specific role of the circuit breaker? How should we choose a circuit breaker? Today we will solve these two problems.
What is the specific role of the circuit breaker
The function of the circuit breaker is to block or penetrate the overloaded circuit, so that it can prevent a safety accident in the circuit. However, although the service life of the circuit breaker is very long, the wrong use method can also cause it to malfunction, so it should not be sloppy when using it.
How to choose a circuit breaker
The circuit breaker can be selected from two aspects, according to the application or according to the function.
The first is the choice of use. Screening is generally based on indoor lighting requirements. For example, if the current of the lighting circuit is not large, you can choose a circuit breaker with a smaller current. However, a circuit breaker with a large label cannot be selected for a current with a small current, because when the current does not reach the number marked on the circuit breaker, the circuit cannot be cut off, causing a series of dangerous accidents.
The second is function selection. If you only need to control a live wire, then we can choose a level 1 circuit breaker. If you want to control a live wire and also have the effect of leakage, then you can choose a level 1 anti-leakage circuit breaker. In addition, the installation position of the level 2 circuit breaker is generally at the main switch, which can usually be used to control the on and off of two lines. The 2-level leakage circuit breaker is generally more suitable for the use of larger power appliances, such as air conditioners, induction cookers and so on. Therefore, when selecting a circuit breaker, it should be screened according to the function of the electrical appliance.
I explained to you what the specific role of the circuit breaker is and how to choose the relevant content of the circuit breaker. I hope I can give you a help.
