Protection of the object from access of solid foreign matter larger than Ø50mm. 2 Protection against medium-size foreign bodies Protection of persons from finger contact with active or internal moving parts. Protection of the object from access of solid foreign matter larger than Ø12mm. 3 Protection against small foreign bodies Protection of persons from contact with active or internal moving parts with tools, wires or similar foreign matter thicker than Ø2.5mm. Protection of the object from access of solid foreign matter larger than Ø2.5mm. 4 Protection against granular foreign bodies Protection of persons from contact with active or internal moving parts with tools, wires or similar foreign matter thicker than > than Ø1mm. 5 Protection against deposits of dust Total protection of persons from contact with voltage carrying or internal moving parts. Protection of the object from harmful deposits of dust. Ingress of dust is not completely prevented, but dust is prevented from entering in a quantity that would impair the functioning of the object. 6 Protection against ingress of dust Total protection of persons from contact with voltage carrying or internal moving parts. Protection of the object from ingress of dust.
