Circuit Breakers – 209-2-36343-1 Application Field and Working PrincipleCircuit breakers are safety devices used to interrupt the flow of electric current when it exceeds predetermined levels. Circuit breakers can be used to protect electrical circuits and components from overloads and short-circuiting. In addition, they provide a safe way to quickly isolate electrical systems and circuits from the power source to address grounding problems or to perform maintenance on the device or circuit. Application FieldCircuit breakers are used in a variety of electrical applications. Residential homes and commercial buildings often use circuit breakers to protect the circuit from damage or interruption should an overload or short circuit occur. Circuit breakers are also used to protect components such as motors or transformers that are connected to the circuit. Circuit breakers are required by electrical codes in order to ensure safe operation of electrical systems. In addition, circuit breakers are necessary to avoid costly repairs or replacement of components that may be damaged by overcurrent or short circuiting. Working PrincipleCircuit breakers work by detecting an electrical overload or short circuit and breaking the electrical circuit. This works by using a type of fusible link that can detect when the current in the circuit exceeds a predetermined level. When this happens, the link causes a mechanical trip that opens the circuit or contacts, thus breaking the circuit. When a circuit breaker trips, it activates a switch that disconnects the load from the circuit. This prevents the current from flowing through the circuit and protects it from damage or destruction. When the issue has been rectified, the circuit breaker can be reset by pressing the reset button. This will reset the contacts and allow the current to flow through the circuit. This can be done manually or automatically and is an important part of the safety features of circuit breakers. ConclusionCircuit breakers are a safety device used to protect electrical systems and components from damage due to overloads and short circuits. Circuit breakers are used in many different application fields, including residential and commercial buildings, motor and transformer protection, and code requirement applications. The working principle of circuit breaker is based on a type of fusible link that can detect when the current in the circuit exceeds a predetermined level. When this happens, the link causes a mechanical trip that opens the circuit or contacts, thus breaking the circuit. The interrupting of the flow of electricity enables the circuits and components to be quickly isolated from the power source for grounding problems or maintenance. When the issue has been rectified, the circuit breaker can be reset by pressing the reset button, allowing the current to flow again through the circuit.
