A circuit breaker is an electrical switch that has been designed to protect the electrical circuit from damage due to overload, overcurrent, or short circuit. The function of this circuit breaker is to stop the flow of current after a fault has been detected through a relay
Although low and medium circuit breakers have unique designs, there are 5 main components of circuit breakers:
- Framework – It is designed to protect the internal part of the circuit-breaker both from the inside and from the outside.
- Operating mechanism – It allows operators to open and close the circuit breaker
- contacts – It allows current to flow through the electrical circuit breaker when it is closed.
- arc extinguisher – When a fault is interrupted by a circuit breaker, the arc helps to extinguish it.
- Trigger – In the event of a prolonged short-circuit or overload, the releases help to open the mechanism.
Types of circuit breakers
Circuit breakers are a certain type of switch that is placed inside the circuit breaker box, which helps protect a home’s electrical components from fire or overheating. In the event of an electrical overload or short circuit, circuit breakers solve the problem by stopping the flow of electricity.
These three types of circuit breakers: arc fault circuit breakers (AFCIs), standard circuit breakers, and ground fault circuit breakers (GFCIs)
Single pole circuit breakers
These circuit breakers are commonly used in residential homes. Single pole, it is designed to monitor the passage of electricity from a single wire or trip in the event of an electrical overload or short circuit. Single pole circuit breakers were designed to accommodate 15 to 30 amps and supply 120 volts of electricity to the circuit.
Double pole circuit breakers
Double pole circuit breakers are designed to monitor the flow of electricity through two wires in parallel. These are generally recognized as single circuit breakers with side-by-side and interconnected switches. These circuit breakers trip if there is a short circuit or overload in one or both wires. It delivers 240 volts or 120/240 volts in an electrical circuit and can accommodate 15 to 200 amps. Double circuit breakers are used to operate appliances that require a significant amount of electricity, such as clothes dryers and washing machines, etc.
These types of circuit breakers are designed to protect a line-to-ground fault. This is specifically used especially when a dangerous electrical path occurs between the electrical current and the grounded item. GFCI circuit breakers also help protect appliances and properties from a current overload or electrical short circuit.
AFCI circuit breakers
AFCI circuit breakers are used when an arc is detected in the spirit of an electrical circuit. It helps by triggering electrical flow, thus preventing the circuit from further damage. Arcing occurs when the electrical cord is damaged or its coating thins, which can pose a major fire threat to its installed space. Regular unipolar and bipolar electric circuits are not equipped to detect the electric arc. AFCI circuit breakers are primarily used in new homes and properties.
How to buy the right type of circuit breaker?
There are several types and suppliers of circuit breakers available in the market. So, when you as a buyer decide to choose the right one, the first thing you need to do is to get as much knowledge as you can about that electrical item.
See what they do, which type fits, the material use for these products, and more. Once you have acquired the basic information, it will be easier for you to choose the right one. Then you need to go online and find the companies that offer the best circuit breakers.
After choosing the provider, contact them through the phone number or email address mentioned on their website. If what they offer meets your needs, you can purchase circuit breakers.
