One of the best ways to describe the function of a circuit breaker (yes, we’re talking about popular choices such as Siemens and Westinghouse circuit breakers) is to monitor the number of amperes passed through the electrical wiring regardless of the purpose.
For example, it can be the circuit breakers used along power lines (that go above 72000 amperes) or even the simple 10, 15 or 20 ampere circuit breakers commonly used for the home.
To say the least, it is a safety device that has been designed to cut off power to any of the appliances in your home if there is a power surge. What happens is that as soon as the breaker detects this, it will cut off the power to the device thus saving it from unnecessary damage. Another advantage is that you can stop an electrical fire that can start due to an overloaded circuit.
In other words, the switch which will normally be in the ‘on’ position will switch back to the ‘off’ position almost immediately.
As mentioned earlier, there are several brands that offer these types of breakers while also carrying a model number (for example, the Square D KA36200 model) which you will have to be cognizant of when purchasing the item.
If you are in need of a circuit breaker, then it is important to know which type of circuit breaker is needed for the purpose you need it for. Each model number meets a certain specification in terms the number of amperes it can handle, thus also suiting situations in which low, medium and high voltage circuit breakers are required.
So if you are in need of a Square D MA36800 circuit breaker, it should be too difficult to find them as there are several online and offline stores that can understand the type of circuit breaker you need and supply it to you immediately.
