If you are getting your home or office constructed or revamped, you might be installing electrical equipment as well. Circuit breakers are installed to ensure the safety of your loved ones and employees. Here you will get to know about circuit breakers.
SF6 Circuit Breaker: In an SF6 circuit breaker, the current that carries contacts operate in SF6 gas and is known as SF6 circuit breaker. It has an excellent insulating property and high electro-negativity. It can be described as the high affinity for absorbing a free electron. The negative ion is formed when a free electron collides with the SF6 gas molecule. It is absorbed by the gas molecule. The negative ions that are formed are heavier in comparison to a free electron. Thus, when compared with other gases, overall mobility of the charged particle in the SF6 gas is less. The mobility of charged particles is responsible for conducting current through a gas. Therefore, for less mobile and heavier charged particles in SF6 gas, it obtains very high dielectric strength. It is this heat transfer property because of low gaseous viscosity makes it an ideal choice for a circuit breaker. It is 100 times more effective in arc quenching media in comparison to an air circuit breaker. It is used for both high and medium voltage electrical power system from 33KV to 800KV. There are different types of SF6 circuit breakers. If you are considering installing it then it is important for you to know about its available types.
Air Circuit Breaker: It is an electrical device used for providing short-circuit and overcurrent protection for electric circuits over 800 AMPS to 10K AMPS. These circuit breakers are generally used in low voltage applications below 450V. It is a circuit operation breaker that operates in the air as an arc extinguishing medium at a particular given atmospheric pressure. There are different types of air circuit breakers easily available in the market. They are easy to install and maintain, durable and high-performing. The advent of the air circuit breakers has completely replaced the use of oil circuit breakers. The wide use of such circuit breakers has added to their popularity. You can easily place an order for any kind of circuit breakers from Crabtree India.
