Overcurrent Protection Devices (OCPDs) are essential components in electrical systems designed to prevent excessive current flow that can lead to overheating and potential damage. These devices, which include circuit breakers and fuses, automatically interrupt the electrical circuit when the current exceeds a predetermined level, ensuring safety and reliability in electrical installations. OCPDs are crucial in various applications, from residential wiring to industrial machinery. By detecting overcurrent conditions, they help protect equipment and reduce the risk of electrical fires. Regular maintenance and testing of these devices are important to ensure they function correctly and provide the necessary protection for both people and property.
