What Are The Advantages Of A Circuit Breaker?

1. What Are The Advantages Of A Circuit Breaker? A circuit breaker is an absolute essential electrical device designed to operate automatically to protect an electric circuit from damage caused by excess current or a fault current. The basic function of the circuit breaker is to interrupt current flow after a fault is detected. The circuit breaker is designed to reset either manually or automatically to resume normal operation. Circuit breakers come in various sizes, from small or residential types that you would find in your home to large industrial sizes that are found in main switch gear or commercial settings. What Are The Components Of The Circuit Breaker? The main components of a circuit breaker are a frame, operating mechanism, interrupting structure, trip unit, and terminal connections. • Frame: This consists of the components (listed below) and also provides insulation to contain the arc. Operating Mechanism: This component opens and closes the contacts in the circuit breaker Interrupting Structure: This specific part includes all the current-carrying parts except the trip unit and arcing probe. Trip Unit: This senses abnormal or faulty current flow and causes the operating mechanism to open the contacts. The circuit trip units are usually a thermal-magnetic type. Terminal Connections: The terminal connections provides a suitable connection from the breaker to the conductor. • • • •

2. How Does A Circuit Breaker Work? The circuit breaker mainly consists of fixed and moving contacts. These contacts touch each other to facilitate carrying the current under normal conditions when the circuit is closed. When the circuit breaker is closed, contacts carrying the current called the electrodes, engage each other under the pressure of a spring. Under normal conditions, the circuit breaker arms can be opened or closed for switching or maintenance of the system. The pressure is required to trigger and open the circuit breaker. If a fault occurs, the trip coil of the circuit breaker gets activated and the moving contacts move apart from each other with an operating mechanism and result in opening the circuit. Advantages of Circuit Breaker: • • • • Circuit-breakers are a great replacement for mechanically operating fuses. Circuit-breakers are highly reliable. Circuit-breakers are more functional. Circuit-breaker can be fixed once, easy to reset and lasts for a long time The following are the leaders in manufacturing the best circuit breakers to meet your needs: 1.
