CAT III equipment is designed to protect against
the transients in the equipment in fixed
equipment installations, such as distribution
panels, feeders and short branch circuits, and
the lighting systems in large buildings.
•
Do not use Clamp in wet environments or in
locations that hazardous gases exist.
