Degree of protection against water, human body and solid foreign material.
Protection degree is specified as per IEC (International Electrotechnical Commission).
|
First figure | Description | |
---|---|---|
0 | No protection | |
1 | Protection against contact with internal live parts by a human hand (ø50 mm ø1.969 in) | |
2 | Protection against contact with internal live parts by a human finger (ø12 mm ø0.472 in) | |
3 | Protection against contact with internal live parts by a solid object more than 2.5 mm 0.098 in in thickness or diameter | |
4 | Protection against contact with internal live parts by a solid object more than 1.0 mm 0.039 in in thickness or diameter | |
5 | Protection against dust penetration which can affect operation | |
6 | Complete protection against dust penetration |
Second figure | Description | |
---|---|---|
0 | No protection | |
1 | No harmful effect due to vertically falling water drops | |
2 | No harmful effect due to water drops falling from a range 15° wider than the vertical | |
3 | No harmful effect due to water drops falling from a range 60° wider than the vertical | |
4 | No harmful effect due to water splashes from any direction | |
5 | No harmful effect due to direct water jet from any direction | |
6 | No water penetration due to direct water jet from any direction | |
7 | No water penetration due to immersion in water under specified conditions | |
8 | No water penetration during immersion, even under conditions that are more harsh than the ones in No.7 |
Note : | The IEC standard prescribes test procedures for each protection degree given above. The protection degree specified in the product specifications has been decided according to these tests. |
