Overcurrent protection is a safety mechanism used in electrical systems to prevent excessive current flow that can lead to overheating and damage. It typically involves devices like fuses and circuit breakers that automatically interrupt the electrical circuit when the current exceeds a predetermined level. This helps protect equipment and reduces the risk of electrical fires. These protective devices are essential in both residential and industrial settings. By ensuring that the current remains within safe limits, overcurrent protection helps maintain the integrity of electrical systems and enhances overall safety. Regular maintenance and testing of these devices are crucial for effective operation.
