IP (ingress Protection) Protection Grade System Is Drafted By IEC (International Electrical Communication), Which Classifies Electrical Appliances According To Their Characteristics Of Dust And Moisture Prevention. The Foreign Objects Mentioned Here, Including Tools, And Human Fingers, Shall Not Touch The Live Parts In The Electrical Appliance To Avoid Electric Shock. IP Protection Grade Is Composed Of Two Numbers. The First Number Represents The Dust-proof And Foreign Object Intrusion Prevention Grade Of Electrical Appliances, And The Second Number Represents The Tightness Of Electrical Appliances Against Moisture And Water Intrusion. The Larger The Number, The Higher The Protection Grade

the first digit indicates the dust prevention index

0. indicates no protection

1. it can prevent the harm of solid above 50mm. (accidental hand contact)

2. it can prevent the harm of solid above 12mm. (finger size object)

3. it can prevent the harm of solid above 2.5mm. (thin wire, etc.)

4. it can prevent the harm of solid above 1mm. (thin wire, etc.)

5. it can prevent the harm of dust

6. completely prevent dust hazards

the second digit indicates the waterproof index

0. indicates no protection

1. it can prevent the hazard of falling vertically into the water

2. it can prevent the harm of direct water spraying at an angle below 150 in the vertical direction

3. it can prevent the hazard of direct water spraying at an angle below 600 in the vertical direction

4. it can prevent the hazard of direct water spray from all directions

5. it can prevent hazards from low-pressure water spray in all directions

6. it can prevent hazards from high-pressure water spray in all directions

7. it can prevent the hazard of immersion between 15cm~1m

8. it can prevent the hazard of long-term immersion under pressure
