Classifies Protection against Touch and Intrusion of Foreign Particles

Code	Description	Level of Protection
0	No Protection	No protection against accidental touch of parts under power or moving or stationary parts.
1	Protection against large foreign parts	Protection against accidental touch of parts under power in large areas or internal moving parts.  Protected against intrusion of particles larger than 50mm diameter
2	Protection against medium foreign particles	Protection against accidental touch with fingers of parts under power or moving internal parts.  Protected against intrusion of particles larger than 12mm diameter.
3	Protection against small foreign particles	Protection against accidental touch of parts under power or internal moving part with tools, wires or similar objects with thickness of larger than 2.5mm.   Protected against intrusion of particles larger than 1mm.
4	Protection against grain-sized particles	Protection against accidental touch of parts under power or internal moving parts with tools, wires, or similar objects with a size larger than 1mm.  Protected against intrusion of parts larger than 1mm.
5	Protection against dust deposit	Complete protection against accidental touch of parts under power or internal moving parts with tools, wires, or similar objects.  Protected against intrusion of dust particles is not completely prevented, but dust particles can not deposit in such quantity that performance is compromised.
6	Protection against intrusion	Complete protection against accidental touch of parts under power or internal moving parts.  Protected against detrimental dust deposition. Intrusion of dust is not completely prevented,  but can not have a detrimental effect on the performance of the device.
