Buy Circuit breaker in bulk at TradeWheel

When it comes to electrical power generation, transmission and distribution, the control of current and voltages turn out to be a vital issue. The question is how to deal with controlling of current. In electronics, the control of current is through series and parallel combinations of resistors. But resistors only limits low currents. 

Where do circuit breakers come in?

When it comes to high current and voltages, circuit breakers are used. We often see circuit breakers of various kinds used in different industries. A fuse is also used to stop the flow of current. However, the fuse is used for low currents and are used one time only. A circuit breaker, on the other hand, prevents the flow of high current by tripping. Tripping of circuit breaker shows that a high current surge was experienced and due to which the breaker tripped. Since it deals in extreme currents, there are different kinds of breakers. Different kinds of circuit breakers are used in different scenarios. The first circuit breaker was suggested by Thomas Edison. 

Do you know what is rating of a circuit breaker?

Circuit breakers are categorized by their ratings which is in Amperes. The greater the ampere level, the greater the capacity a breaker has to prevent current. What is important is to understand is what kind of rating a circuit breaker have and which equipment it should be used with. In different industries, there are panels of breakers. And these panels combine to form switchgear. There are different kinds of breakers in switchgear. Low voltage circuit breaker, high voltage circuit breaker, air circuit breaker, vacuum circuit breaker, molded case circuit breaker, etc. Residential uses circuit breakers being used are miniature circuit breakers or molded case circuit breaker as they have low ampere rating and are suited best for households.
