* Voltage peak or DC

** Voltage rms (sinusoidal)

Note: F = Functional

B/S = Basic/Supplementary

R = Reinforced

Note: Linear interpolation is permitted between the nearest two points, the calculated spacing being rounded to the next higher 0.1 mm

increment.

The following separations require the specified insulation grade:

• TNV3 from TNV3 — functional insulation

• TNV3 from SELV — basic insulation

• TNV3 from TNV1 — basic insulation

• TNV3 from TNV2 — basic insulation
