What are the IP protection classes?

IP (INGRESS PROTECTION) protection level system is drafted by the International Electrotechnical Commission IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION). Electrical appliances according to its dust and moisture characteristics to be graded. The foreign objects referred to here include tools, human fingers and so on can not touch the electric part of the electrical appliances to avoid electric shock. ip protection level is composed of two numbers, the first number indicates the scope of the equipment resistance to dust, or the degree of people in the sealed environment from the harm. ip stands for the level of prevention of entry of solid foreign bodies, the highest level is 6 the second number indicates the degree of waterproof equipment. P represents the level of protection against water ingress, the highest level is 8

Such as the motor protection level IP65, protection level IP55, etc., the larger the number indicates that the higher the level of protection.

The two labeled numbers indicate the level of protection as shown in Table I and Table II.

Table I I represents the level of protection against the entry of solid foreign objects

0 No protection No special protection against external persons or objects

1 Protection against the intrusion of solid foreign objects with a diameter of more than 50mm Protection against the human body (e.g., the palm of the hand) accidentally coming into contact with the internal parts of the appliance, and protection against the intrusion of large-sized foreign objects (diameter of more than 50mm)

2 Protection against the intrusion of solid foreign objects with a diameter of more than 12mm Protection against the intrusion of solid foreign objects with a diameter of more than 12mm 12mm in diameter Prevents human fingers from coming into contact with internal parts of the appliance, and prevents the intrusion of medium-sized (12.5mm diameter or larger) foreign objects

3 Prevents the intrusion of solid foreign objects larger than 2.5mm in diameter Prevents the intrusion of tools, wires, and similar small foreign objects with a diameter or thickness of more than 2.5mm from coming into contact with internal parts of the appliance

4 Prevents the intrusion of solid foreign objects larger than 1.0mm in diameter from coming into contact with internal parts of the appliance Prevents the intrusion of solid foreign objects larger than 1.0mm in diameter Prevents the intrusion of tools, wires, and similar small foreign objects larger than 1.0mm in diameter or thickness from coming into contact with the internal parts of the appliance

5 Protection against foreign objects and dust Completely protects against foreign objects and dust, and does not prevent the intrusion of dust completely, but the intrusion of dust is not in an amount that affects the normal operation of the appliance

6 Protection against foreign objects and dust Completely protects against foreign objects and dust, and prevents the intrusion of foreign objects, and prevents the intrusion of foreign objects into the appliance. Table 2P represents the level of protection against water ingress

0 No protection No special protection against water or moisture

1 Protection against water droplets Droplets falling vertically (e.g., condensation) will not damage the appliance

2 Protection against water droplets even when tilted at 15 degrees Droplets will not damage the appliance when tilted at 15 degrees from vertical.

3 Protection against sprayed water Protection against rain or damage caused by water sprayed at an angle of less than 60 degrees from the vertical

4 Protection against splashing water Protection against damage caused by water splashed from all directions

5 Protection against sprayed water Protection against damage caused by water sprayed from nozzles from all directions

6 Protection against large waves

7 Protection against heavy waves

8 Protection against water dripping from the appliance when tilted at an angle of 15 degrees from vertical. Damage
