What does "overcurrent protection" refer to?

Overcurrent protection refers to devices specifically designed to prevent excessive current flow in an electrical circuit. When the current exceeds a predetermined level, these devices automatically interrupt the flow of electricity, protecting both the wiring and connected equipment from damage caused by overheating or potential fires. This safety measure is crucial in electrical systems to ensure operational reliability and to prevent accidents.

Devices such as circuit breakers and fuses are common examples of overcurrent protection. These devices are integral to maintaining system integrity and safety, making it essential for anyone working with electrical systems to understand their function and importance.
