Two figures represent marked protection class as shown in Table 1 and Table 2 as shown in
Digital | Protection range | Explain |
0 | Unprotected | No special protection to the persons or things outside |
A | Prevention of diameter greater than 50mm solid foreign matter | Foreign matter to prevent the body (such as the palm of your hand) accidentally come into contact with an electrical appliance parts, to prevent the larger size (diameter greater than 50mm) |
2 | Prevention of diameter greater than 12mm solid foreign matter | Foreign matter to prevent a human finger to come into contact with electrical parts inside to prevent the medium size (diameter greater than 12.5mm) |
3 | Prevent solid foreign matter larger than the diameter of 2.5mm | To prevent the diameter or thickness greater than 2.5mm tools, wires and similar small intrusion of foreign objects come into contact with an electrical appliance parts |
