Which of the following would best describe a characteristic of "Enclosed" equipment?

Enclosed equipment is characterized by being protected from physical damage, which ensures durability and safety in various environments. This enclosure serves to shield the internal components from external hazards such as mechanical impacts, environmental elements, and unauthorized access. In many applications, this protection helps maintain both the functionality of the equipment and the safety of personnel working around it.

The other options do not accurately describe the nature of enclosed equipment. Open design would not adequately protect the equipment and makes it less suitable for environments where safety and damage prevention are priorities. Visible and accessible energized parts contradict the purpose of an enclosure, which is to minimize exposure to live components. Lastly, while some enclosed equipment may require specific mounting strategies, describing it as needing complex mounting does not define its enclosed characteristic and may vary widely based on the specific type of equipment in question.
