In limited-energy cabling, what is the function of a surge protector?

A surge protector serves a critical role in limited-energy cabling by preventing voltage spikes from damaging sensitive equipment. In electrical and electronic systems, various factors—such as lightning strikes, utility switching, or equipment malfunctions—can cause sudden increases in voltage known as surges. These surges can exceed the voltage rating of devices connected to the cabling, potentially leading to significant damage or functional failure.

The surge protector acts as a barrier, effectively redirecting excess voltage away from the equipment it is designed to protect. This strategy helps maintain the integrity of sensitive devices, ensuring they operate correctly and remain safe from harmful power fluctuations. By doing so, surge protectors contribute to the overall reliability and longevity of the cabling system and connected devices.

Other choices relate to different aspects of signal management and integrity but do not directly address the protective capabilities against voltage surges, which is the primary purpose of surge protectors in cabling systems.
