in this standard, in view of the electrical equipment enclosure protection of foreign body, the format of the IP rating for IPXX, where XX is two digits, said the tag number contact protection and foreign body protection level, the second tag Numbers waterproof protection level, the specific protection grade can refer to the table below.
