•
•
•
•
A capacitor of a type suitable for use in situations
where failure of the capacitor could lead to
danger of electric shock.
ClassY capacitors are divided into sub- classes
based on type of insulation bridged and voltage
ranges.
For definitions of basic, supplementary,
double and reinforced insulation, see IEC
