What is the primary function of overcurrent protection in control systems?

The primary function of overcurrent protection in control systems is to prevent excessive current flow that can damage equipment. This protective mechanism is crucial because when the current exceeds the designed limits of a system, it can generate excessive heat, leading to potential failures such as insulation breakdown, component burnout, or even fire hazards. By incorporating overcurrent protective devices, such as fuses or circuit breakers, systems can automatically disconnect to limit damage and maintain safety.

While controlling voltage levels, ensuring signal integrity, and maintaining power levels are important functions in various contexts, they do not specifically address the risks associated with excessive current. Thus, the focus on preventing overcurrent makes that option the most relevant.
