Overcurrent protection

In electrical and electronic circuits, this is a mechanism that protects the secondary circuit by stopping the output, such as by shutting off the circuit, when an abnormal current exceeding the rated value caused by a short circuit or current leakage is detected at the sensing part on the circuit. It is synonymous with OCP. When the cause of the overcurrent is removed, some systems recover automatically, while others require manual recovery after a person confirms safety. Overcurrent protection functions are widely used, from power transmission and distribution circuits that handle large amounts of power to electronic circuits that handle small amounts of power. In power transmission and distribution circuits, overcurrent protection also plays an important role in preventing electrical accidents such as electric shock and leakage.
