IP ratings of equipment cabinets

IP ratings of equipment cabinets
IP ratings define protection types according to the standard EN 60 529/IEC529.

Protection type is stated like:

IP [First digit][Second digit]

For example:

[First digit] = 5 means that the cabinet is protected against dust. Dust can penetrate into the cabinet, but only in those proportions which will not affect the operation or safety of the cabinet.

[Second digit] = 5 means that the cabinet is protected against water stream. If water is directed from each direction at the cabinet as a stream, it will not cause harmful effects.

[Second digit] = 6 means that the cabinet is protected against strong water stream. If water is directed from each direction at the cabinet as a strong stream, it will not cause harmful effects.
