Circuit breakers are an electrical switch which is operated and designed to protect an electrical circuit from destruction. Damage can occur to an circuit or circuit breaker when there is an overload of electricity or short-circuit.

The essential function of business circuit breakers or circuit current sensor is to sense a fault condition. If there is any fault, the breakers discontinue the electrical current. Made of varying sizes, industrial breakers can be reset manually or automatically to resume regular function.

Breakers can be a small device to guard a single household appliance or huge switchgear fashioned to safeguard high voltage circuits that supply a complete town. There are 3 types of circuit breakers based mostly on their voltage.

A low-voltage breaker is made for circuits at 1000 volts or less. The molded circuit breaker is one of the most commonly used low-voltage air circuit current sensor. This is the breaker used often in homes, certain industrial uses and enterprises.

Types of low-voltage circuit breakers include the Miniature Circuit Breaker or MCB, and Molded Case Circuit ...
... Breaker or MCCB. The MCBs are for uses with electrical energy rate not exceeding 100A. They will be used as thermal or thermal-magnetic operations.

Low-voltage breakers are mounted inside draw-out enclosures to permit removal and interchange without dismantling switchgear. The big low-voltage molded case and power breakers have electrical motor operators to open and shut them using remote control.

Medium-voltage circuit breakers are intended for applications requiring voltage of higher than 1,000 however no more than 2000. They will be used indoor or outside. For indoor function, a circuit breaker is used along with enclosed switchgear lineup. For outside function, a circuit breaker is used as an individual element installed in substation.

There are three types of medium-voltage breakers. These are vacuum circuit breaker, air circuit breaker and SF6 circuit breaker. A vacuum circuit current sensor is employed for electric volts of 3000 A. it's used to interrupt the electrical flow by creating and extinguishing the arc in a vacuum container.

Air circuit breaker is for uses of 10,000 A. It is typically used for main power distribution in massive industrial plants to have simple and convenient maintenance. SF6 circuit breakers extinguish the arc in a container filled with sulfur hexafluoride gases.

Medium-voltage breakers can be connected into a circuit by bolted connections to bus bars or wires, specifically in switchyards found in most outdoors. These breakers, which are lined-up in switchgear, are created with draw-out construction. This construction is helpful in removing the breaker without interrupting the power circuit connections.

High-voltage circuit breakers are used if the electric voltage is 72,500 or higher as set by the International Electro-technical Commission. The underlying characteristic in most of the 3 types of circuit breakers is their solenoid function.

High-voltage circuit current sensors are used to shield and control electrical power transmission networks. They're equipped with current sensing protective relays maneuvered through electric transformers. They're categorized consistent with the tool used to extinguish the arc, that consists of the air blast, minimum oil, bulk oil, vacuum and SF6.
