What is a Circuit Breaker? |
|
Answer:
A circuit breaker is a safety component used in electrical systems, Circuit breakers look somewhat like wall switches, with a toggle lever that opens and closes the circuit. Circuit breaker designs vary by manufacturer and by specific need (i.e., high or low voltage or amperage). Circuit breakers are typically installed in main electrical panels (as in a residence or small commercial building) or local distribution panels (as may be used for larger office and factory lighting controls). Some of the types of circuit breakers available are: o Magnetic circuit breakers: Use electromagnetic solenoid to make or break a circuit based on current flow and safety set points. o Thermal circuit breakers: Use bi-metallic components which heats up and bends as current rises, and trips at safety set points. o Thermo-magnetic circuit breakers: Use both above methods; using the magnetic mechanisms to react to large current surges (i.e., short circuits), and the thermal mechanisms to react to less serious but perhaps longer lasting issues (i.e., current overloads).
