Technical Information: Degrees of Protection
IEC Publication 60529 Classification of Degrees of Protection Provided by Enclosures provides a
system for specifying the enclosures of electrical equipment on the basis of the degree of protection
provided by the enclosure. IEC 60529 does not specify degrees of protection against mechanical
damage of equipment, risk of explosions, or conditions such as moisture (produced, for example, by
condensation), corrosive vapors, fungi, or vermin. NEMA Standards Publication 250, and UL 50
Standard does test for environmental conditions such as corrosion, rust, icing, oil, and coolants. For this
reason, and because tests and evaluations for other characteristics are not identical, the IEC Enclosure
Classification Designations cannot be exactly equated with NEMA Enclosure Type Numbers.
The IEC designation consists of the letters IP followed by, usually, two numerals (for example IP 55). The
first characteristic numeral indicates the degree of protection provided by the enclosure with respect to
persons and solid foreign objects entering the enclosure. The second characteristic numeral indicates
the degree of protection provided by the enclosure with respect to the harmful ingress of water. See the
tables below and on page 13 for what the two numbers mean.
In addition, a single-digit letter may follow the two numerals (for example, IP 20C). This letter indicates
that the actual protection of personnel against direct contact with live parts is better than that indicated
by the first numeral. So this example (IP 20C) indicates that the device is finger-safe (the ‘2’) and tool-
safe (the ‘C’) for tools 2.5 mm (or larger) in diameter. See the table on page 13 for what letters are
permissible and what each indicates.
Finally, a third numeral may sometimes appear and corresponds to the degree of protection against
mechanical impact. In accordance with standard NF C 20-010, the third numeral may either follow the
two IP numerals (for example, IP 55-9) or be shown separately from the IP code. This numeral also
corresponds to an external factor classification as defined in standard NF C 15-100. See the table on
page 13 for what numbers are permissible and what each indicates.
NOTE: Any characteristic numeral which is unspecified is replaced by an X (for example, IP XXB).
