Circuit Protection

Circuit Protection.jpg
Circuit protection is a crucial aspect of electronic components classification. It refers to the measures taken to prevent damage to electronic circuits due to overvoltage, overcurrent, or short circuits. Circuit protection devices such as fuses, circuit breakers, surge protectors, and voltage regulators are used to safeguard electronic components from damage caused by power surges, lightning strikes, and other electrical disturbances. These devices are designed to interrupt the flow of current when the voltage or current exceeds a safe level, thereby protecting the circuit and preventing damage to the electronic components. Circuit protection is essential for ensuring the reliability and longevity of electronic devices and systems.
