Design of clearances and creepage distances in
electrical equipment
General
Since April 1997 the sizing of clearances and creepage dis-
tances has been covered by DIN VDE 0110, part 1 “Insulation
coordination for electrical equipment in low-voltage systems”.
DIN VDE 0110, part 1 contains the modified edition of IEC
Report 664-1 (see also IEC 664-1/Oct 1992). Since April 2003,
the rules of DIN EN 60664-1 / 11.03 in conjunction with DIN 61984
/ 09.02 apply to the dimensioning of clearances and creepage
distances.
The design data resulting from these provisions is – if applicable
– specified in this catalogue for each product.
For the design of clearances and creepage distances, applica-
tion of the regulations for insulation coordination produces the
following interrelationships:
Clearances
Clearances are rated in accordance with the following factors:
• Anticipated overvoltage
• Used
• Measures to prevent pollution

rated impulse withstand voltage
overvoltage protection precaution
pollution severity
Creepage distances
Creepage distances are rated in
accordance with the following factors:
• Planned
• Insulation materials used
• Measures to prevent pollution
Slots are taken into account when measuring creepage dis-
tances if their minimum width X is dimensioned according to
the following table:
Pollution severity

If the associated clearance in air is less than 3 mm, the
minimum slot width can be reduced to 1/3 of the
clearance.
