Circuit Breakers
Electric circuit breaker: Perfect replacement of fuses
Electric Circuit breaker is a device which is used to control electrical power networks by switching circuits on, by carrying load and by switching circuits off under manual or automatic supervision. The role or function of circuit breaker is little unusual as they will usually be in the closed position carrying load, or in the open position providing electrical isolation. Today, these devices are often used at residential and industrial locations.
Circuit breakers have the major duty of altering one condition to the other only occasionally, and to execute their special function of closing on to a faulty circuit or interrupting short-circuit current only on very rare occasions. Thus, the circuit breaker you install ( for home or industrial purpose) must be reliable in the static situations, but be effective instantly when they are called on to perform any switching operation, often after long periods without movement.
Today, electric circuit breakers are available in different sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city. They are also made in different measures to meet different needs such as there are home circuit breakers, standard circuit breakers and industrial circuit breakers etc.
Now, circuit breakers have become an ultimate replacement of fuses, in fact considered as the preferred type of circuit protection. Technically, they are called molded-case circuit breakers, or MCCBs. Circuit breaker use a two-part system for protecting circuit wiring. When a small overload is on the circuit, a thermal strip will heat up and open, or trip, the circuit. When massive amount of current comes through very quickly, as in ground fault or short circuit, an electromagnet gives the thermal strip a boost. The greater the amount of trip current, the faster the breaker will trip.
The great benefit circuit breakers have over fuses is that they can be reset without too much effort; you don't have to place a new one every time an appliance draws excessive current. Moreover, when a breaker closes off the circuit, it won't work unless you throw it all the way to the off position before you turn it back on again. One more feature of electric circuit breaker is that it is air-ambient compensated— the hotter the air around them gets, the sooner they will trip.
In addition, standard circuit breakers are worldwide and have clips on the bottom that snap onto the hot-bus tabs in the panel box. Contact with the hot bus brings power into the breaker. But, you should be also aware that some manufacturers make breakers with wire clips that mount on the side. These clips slide over the tab on the hot bus, requiring you to remove one or more of the other breakers to get at the one you want. Presently, there are various online stores available on the internet that offer home circuit breakers, industrial circuit breakers and other types of breakers with detail information.
