IEC clearance and creepage distances
Dimensioning creepage distances
Decisive for dimensioning creepage
distances are the rated voltages derived
from the system voltages the power
supply for the respective type supply
system conjunction with the pollution
severity (classification, see “Clearances”)
and the insulating material used.56 0.50 1.00 1.60 1.20 5.11 0.75 1.90 2.09 0.30 1.53 1.30 2.025 0.53 0.00 12.00 5.04 0.10 2.00 0.20 1.08 0.40 2.10 0.00 2.
Note application pollution
severity and overvoltage categories
The pollution severity and rated impulse
withstand voltage derived from the
overvoltage category are each specified
in this catalogue and are product-related.60 0.50 0.10 1.60 1.80 2.8
