Question 68
Subject:
Insulation properties of housing
of subclass Y capacitors
Key words:
- subclass Y capacitor
- housing
- insulation
Decision approved
at the 46th CTL
Plenary Meeting
2009
Question:
Capacitors complying with IEC 60384-14 are permitted to bridge certain levels of
insulation. Does the housing of such capacitors provide this same level of
insulation?
Example: A subclass Y1 capacitor is permitted to bridge double or reinforced
insulation. Is it permitted that this capacitor housing serves as double or reinforced
insulation to other circuit parts, such as a transformer core?
Decision:
Housings of IEC 60384-14 subclass Y capacitors are considered to provide
insulation levels as specified in IEC 60950-1 (e.g. Table 1D for 2nd ed.) with the
exception of the areas near to the leads.
