Circuit Protection Device. A circuit breaker is one kind of electrical switch used to guard an electrical circuit against short. So we can see that there are many different potential sources of damage but how can we protect our circuits from such damage.
However unlike silicon diodes when used in reverse bias mode they will clamp. They are used as the name implies to protect either the power supply from being forced to deliver excessive current into overload or short circuit or to protect the connected circuit from a reverse connected power supply or a voltage that exceeds the circuit design voltage. Zener diodes series limiting resistors.
An overloaded circuit occurs when there s too much current flowing through the circuit.
In electrical circuits a fuse is an electrical device used to protect the circuit from overcurrent. About fuses a fuse is a base element for short circuit protection. All electronic devices need protection circuits. What is electrical circuit protection.
