IP is the abbreviation of Ingress Protection. IP grade is the protection level for electrical equipment shell against the foreign body intrusion. It comes from the international electrical commission standard IEC 60529 which was also used as the national standard of America in 2004. In this standard, for the protection level of electrical equipment shell against the foreign body intrusion, the IP level format is IPXX. In which the XX are the two Arabia number. The first tag number indicates the protection level of contact protection and external object protection; the second tag number indicates the protection level of waterproof. For the more specific protection level can refer to the table below.
Level of protection usually uses IP with the following two figures to express. The numbers used to specify the protection level. The first number indicates the range of the device against dust, or the extent of people against damage in sealed environment. ‘ I ‘ represents the level of prevention of the entry of solid foreign bodies, and the highest level is 6; the second number indicates the level of the device against water. P representative the level prevent from water, the highest level is 8. Such as the protection level of motor IP65, IP55 and so on.
