IP DEGREE OF PROTECTION
DEGREES OF PROTECTION FOR ENCLOSURES
The IEC / EN 60529 Standard establishes a classification system for the degrees of protection of enclosures for electrical equipment whose rated voltage does not exceed 72.5 kV.
Its purpose is to specify the degree of protection of electrical equipment enclosures, the designation of these degrees of protection, the requirements for each designation and the verification tests.
According to these Standard, the IP degree of protection should be used exclusively with the 2 defining numbers and the additional letters. These are defined as follows:
Protection for people from contact with hazardous parts (see also ADDITIONAL LETTER) and protection of equipment from the entry of solid foreign bodies.
Protection of equipment from water entry.
To be used when the protection of people from hazardous parts is higher than that demanded by the first number for protection from the entry of solid objects.
Used to supply additional information about the material.
