Have you often seen characters like IPXX (where XX represents numbers) on stage electric hoists? Do you know what they mean? Also, what are the different implications of the numbers?
IPXX refers to the protection rating of the motor of stage electric hoists. Here, XX represents numbers, where the first number indicates the dust protection level, and the second number indicates the water protection level.
The first number ranges from 0 to 5. The larger the number, the higher the dust protection level. The second number ranges from 0 to 8. The larger the number, the higher the water protection level. So, what exactly does each specific number protect against?
First, regarding the dust protection level: 0 means no protection; 1 means protection against the intrusion of large solids; 2 means protection against the intrusion of medium - sized solids; 3 means protection against the entry of small solids; 4 means protection against the entry of solids larger than 1mm; 5 means protection against the accumulation of harmful dust; 6 means complete protection against dust entry.
