Circuit Breakers – An Ideal Solution that Keeps Electrical Circuits Away from Damage


Circuit Breakers

How to Protect Electrical Circuit from Damage

A circuit breaker is designed to protect an electrical circuit from damage if it ever short circuited or from overloading. This is an electrical switch that is automatically operated in the event of overload. Its core function is to interrupt the current flow when it detects a fault condition. Unlike a fuse, a circuit breaker does not have to be replaced after its operation. The circuit breaker can be reset, manually or automatically, to go back to original operation. They come in various sizes and functions, from protecting individual household appliances to entire cities. All circuit breakers have several common features in their operation, but their details will vary depending on the current rating, voltage class, and the type of circuit breaker. In order for circuit breakers to work, they must be able to detect the fault condition within the electrical circuit. Once the fault is detected, the contacts within the breaker open in order to interrupt the entire circuit. The contacts are disconnected by using some sort of mechanically-stored energy contained inside the circuit breaker. Smaller circuit breakers may be required to be manual reset, but larger ones usually have solenoids that trip the mechanism and motors to reset the breaker. The contacts must be able to carry the load current without excessive heating as well as withstanding the heat of the arc produced when breaking the contacts. Contacts are usually made of copper or copper alloys, silver alloys, and other conductive materials. There is a service life with the contacts which is determined by the erosion of the material from the heat of the arc. Contacts in smaller breakers cannot be replaced and thus, the entire circuit breaker must be replaced. Go for best Distributors of  circuit breaker.
