Final Report Lot 9: Public street lighting - Amper

Applies to the classification of degrees of protection provided by enclosures for
electrical equipment with a rated voltage not exceeding 72,5 kV. Has the status of a
basic safety publication in accordance with IEC Guide 104.
Degree of protection code IP X1X2:
X1 indicates the degree that persons are protected against contact with moving parts (other than
smooth rotating shafts, etc.) and the degree that equipment is protected against solid foreign
bodies intruding into an enclosure;
• X1 = 0 means no special protection
• X1 = 1 means protection against penetration by large foreign bodies, d>50 mm
No protection against intentional access
• X1 = 2 means protection against small foreign bodies, d>12mm, exclusion of fingers or
similar objects
• X1 = 3 means protection against small foreign bodies, d>2.5 mm, exclusion of tools,
wires or similar objects
• X1 = 4 means protection against grainy foreign bodies, d>1 mm, exclusion of tools,
wires or similar objects
• X1 = 5 means protection against dust deposits (dust protected), complete exclusion of
access
• X1 = 6 means totally protection against dust deposits (dust protected), complete
exclusion of access.
X2 indicates the degree of protection of the equipment inside the enclosure against the harmful
entry of various forms of moisture (e.g. dripping, spraying, submersion, etc.);
• X2 = 0 means no special protection
• X2 = 1 means protection against drops of water falling vertically
• X2 = 2 means protection against water falling at an angle (water drop), inclined at 15°
to the normal operating position
• X2 = 3 means protection against water spray, up to 60° from the vertical
• X2 = 4 means protection against water splashes from any direction
• X2 = 5 means protection against water jet from any direction
• X2 = 6 means protection against heavy sea or strong water jet
• X2 = 7 means protection against submersion in water at a certain pressure and for a
certain period
• X2 = 8 means protection against continuous submersion in water.
Example: IP65 means totally protection against dust deposits (dust protected), complete
exclusion of access and protection against water jet from any direction.
