The difference between the protection level of explosion-proof motor ip65 and ip55

The previous number in the protection level IP65 of the explosion-proof motor represents the dustproof level of the motor. The higher the level, the better the dustproof effect. In the explosion-proof motor, the protection level 6 is the highest level. This kind of motor can become a dust-tight motor, and 6 means that dust cannot enter. A number 5 after each other represents the waterproof level, and water spraying in any direction has no harmful effect. The waterproof level is up to 8. This means that the appliance is submerged indefinitely under the specified water pressure, which ensures no damage due to submersion.
The protection level of IP55 is level 5, which represents the protection of metal wires (diameter greater than 1mm) and the prevention of harmful dust accumulation; the protection level of IP65 is level 6, which means complete protection against dust entry.
In explosion-proof motors, the IP55 level usually refers to places such as Class I mines, Class II gas floors, etc. IP55 meets the needs of most environments, while in Class III dust environments, it needs to be completely dust-proof and requires protection class IP65.
