representation method

protection level is mostly expressed by IP followed by two numbers, and the numbers are used to clarify the protection level.

indicates the range of dust resistance of the equipment, or the degree to which people are protected from harm in a sealed environment. Represents the level of prevention of solid foreign matter, the highest level is 6;

second digit indicates how waterproof the device is. Represents the level of prevention of water ingress, the highest level is 8.

without protection

No special protection for people or things outside

1

Prevent the intrusion of solid foreign objects with a diameter greater than 50mm

Prevent the human body (such as the palm) from accidentally contacting the internal parts of the electrical appliance, and prevent the invasion of foreign objects of larger size (diameter greater than 50mm)

2

Prevent the intrusion of solid foreign objects with a diameter greater than 12.5mm

Prevent human fingers from touching the internal parts of the appliance and prevent the intrusion of medium-sized (diameter greater than 12.5mm) foreign objects

3

Prevent the intrusion of solid foreign objects with a diameter greater than 2.5mm

Prevent tools, wires and similar small foreign objects with a diameter or thickness greater than 2.5mm from intruding into the internal parts of the electrical appliance

4

Prevent the intrusion of solid foreign objects with a diameter greater than 1.0mm

Prevent tools, wires and similar small foreign objects with a diameter or thickness greater than 1.0mm from intruding into the internal parts of the electrical appliance

5

Prevent foreign objects and dust

Completely prevent the intrusion of foreign objects, although it cannot completely prevent the intrusion of dust, the amount of dust intrusion will not affect the normal operation of electrical appliances.

6

Prevent foreign objects and dust

Completely prevent foreign objects and dust intrusion

without protection

No special protection against water or moisture

1

Prevent water droplets from entering

Drops of water falling vertically (such as condensed water) will not cause damage to electrical appliances

2

is tilted 15 degrees, it can still prevent water droplets from entering

When the appliance is tilted from vertical to 15 degrees, dripping water will not cause damage to the appliance.

3

to prevent the sprayed water from entering

Protect from rain or prevent water sprayed in a direction less than 60 degrees from the vertical from invading the appliance and causing damage

4

prevent splashing water from entering

Prevent water splashing from all directions from invading the appliance and causing damage

5

to prevent water from being injected

Prevent water from all directions from the nozzle from invading the appliance and causing damage

6

prevent large waves from dipping

Electrical appliances installed on the deck to prevent damage caused by large waves

7

Prevents water from entering during flooding

the appliance is immersed in water for a certain period of time or the water pressure is below a certain standard to ensure that it is not damaged due to immersion.

8

to prevent the immersion of water when sinking

can be completely immersed in water structure, the experimental conditions by the producers and users to determine
