5 If the associated clearance air is less than mm, the minimum slot width can reduced 1/3 the clearance.Electrical data Since April 1997 the sizing of clearances and creepage distances has been covered IEC 60664-1 “Insulation coordination for electrical equipment low-voltage systems”.25 2 1 3 1.16 1282250000 2012/2013 . For the design clearances and creepage distances, application of the regulations for insulation coordination produces the following interrelationships: Clearances Clearances are rated accordance with the following factors: • Anticipated overvoltage rated impulse withstand voltage • Used overvoltage protection precaution • Measures prevent pollution pollution severity Creepage distances Creepage distances are rated in accordance with the following factors: • Planned rated voltage • Insulation materials used insulation group • Measures prevent pollution pollution severity Slots are taken into account when measuring creepage distances their minimum width dimensioned according the following table: Pollution severity min.5 4 2. The design data resulting from these provisions applicable specified in this catalogue for each product.
