The circuit breaker is a type of device which is designed to prevent any incident of electrical overloads. This device stops any kind of damage to electrical appliances and devices and automatically shut it down before further damage. Thus, every home or business own at least one type of circuit breaker. There are several types of circuit breakers available in the market and each vary depending upon various considerations such as power capacity or whether an individual circuit breaker is consistent with a breaker panel. The Circuit breaker is mainly of three types - standard circuit breakers, ground fault circuit interrupter circuit breakers, and arc-fault circuit interrupter circuit breakers.
One needs to evaluate various factors before purchasing a circuit breaker. This includes amp rating, continuous current rating, interrupting capacity, product testing and unusual operating conditions. Amp rating refers to the utmost number of amperes that the circuit breaker can handle. To determine the amp rating for the electric circuit, one has to calculate the total electrical load that the circuit need to bear. Interrupting rating refers to the maximum quantity of fault current that the circuit breaker can interrupt without creating any failures. The continuous current rating refers to the ampere rating that the breaker can carry in the habitat temperature where it was standardized.
Apart from these considerations, one of the factors that determine the functionality of the fuser is the voltage capacity. All the circuit breakers are accordingly categorized into high, medium and low voltage capacity.
High voltage circuit breaker is primarily used for those electrical systems that are positioned outside the house and can handle minimum 1500 volts. For example, the transmission networks which distribute power from the sources to the customers. High voltage fuser uses various methods to break the circuit such as minimum oil or bulk oil. However, considering the various environmental concerns, the recent fuser uses gas. The high voltage circuit breakers are more expensive to ship than the low voltage ones. Medium voltage circuit breakers are designed to handle maximum 1500 volts. These types of breakers are often found in gas turbines, pumped storage, etc. At times, they are also grouped with the other two types of voltage breakers.
The low voltage circuit breaker are designed to handle the minimum i.e. 600 volts of current. This type of breaker is mostly suitable for homes. They are also found in industrial buildings and small businesses. While they have an ample of methods to do their job, the most commonly used low voltage breaker is the thermal-magnetic one. Before one purchases the circuit breaker, it’s wise to compare their prices online as it will enable the user to spend his/her money effectively. One can also go through the users reviews as they will provide the buyer with a clear understanding of the actual performance of the breakers. Also users can look out for discounts as provided by the various dealers.
