Circuit Breakers

Electronic equipment is often designed with built-in circuit protection. The main function is to provide protection to both the equipment and the equipment operator in the event of a circuit overload.

In principle, a circuit breaker is like a fuse—it can open the circuit pathway in the event of an overload or short circuit. Unlike the fuse, the circuit breaker is reusable. It is available in a manual or automatic reset. A manual reset requires the user to press a button or move a lever (or switch) to reset the circuit pathway. An automatic reset will return to normal functioning once normal conditions resume.

Circuit breakers only protect against low-level faults and are not meant to clear faults with high-voltage levels. A circuit breaker is not a surge resistor for catastrophic events, such as lightning strikes or high-voltage line shorts.
