Peter,

Peter,
I understand you want to use this capacitor between the Central Office battery
and Ground (Protective Earth).
Why do you need Basic Insulation anyway if you interconnect to Protective Earth.
From my point of view, you only need Operational insulation.

Hello Peter:
According to IEC 384-14, the capacitor types suitable to bridge BASIC
INSULATION are Y2, Y3, or Y4 capacitors. According to the voltages you
specify, a Y4 cap would be suitable.
The thing to keep in mind here is clause 1.5.3 of IEC 384-14, which defined
an X capacitor as: A
4 matches
