Detailed Description for AC Circuit Breaker

 

A circuit breaker is an automatic electrical switch, which is designed to protect the electrical circuit from potential damage, which may cause due to current overload or short-circuit. The basic function of the breaker is to disrupt the flow of electricity after protective relays detect a fault.

 

Unlike any other fuse that operates at once and then ought to be replaced, the circuit breaker can be reset (either automatically or manually) to resume its operation. These breakers are available in different sizes, right from small device, which protects an individual household appliance to large switchgear that are designed to guard high voltage circuits feeding a complete city. The key function of a circuit breaker is to restrict the flow of power from a faulty system.

 

 

Circuit breakers are manufactured in various sizes and use a system of preferred numbers to cover a wide range of power ratings. The miniature circuit breakers are designed for a fixed trip setting where as changing the operating current value necessitates changing the whole circuit breaker. Larger circuit breakers have variable trip settings, which allow homogeneous elements to be applied, but with a setting that are intended to enhance protection.
