What does the term "limited energy" refer to in hazardous classification?

The term "limited energy" specifically refers to energy levels that are deemed to be insufficient to ignite an explosive atmosphere. In hazardous locations where flammable gases, vapors, or dusts may be present, it is critical to manage energy sources to prevent ignition sources from occurring.

Components that are classified as having limited energy are designed to operate within a range that minimizes the risk of sparks or other ignition sources, thereby enhancing safety in environments where hazardous materials are prevalent. This classification is crucial in defining which equipment can be safely used in such locations.

Understanding this concept is important for compliance with safety standards and regulations regarding equipment used in hazardous locations, ensuring that installations can function safely without posing a risk of ignition to flammable substances.
