DESCRIPTION OF ISSUE:
Type of Issue: Technical/Certification
What insulation level may the casing of X1, X2, X3, Y1, Y2, and Y3 capacitors under IEC
60384-14, and X1, Y1 and Y2 capacitors under UL 1414 (FOWX2), and capacitors under UL
1283 (FOKY2) be relied upon to act as?
APPLICATION GUIDELINE:
Capacitor casings of Certified X1, X2, X3, Y1, Y2 or Y3 capacitors to IEC 60384-14 may be
accepted as Operational or Basic insulation when the capacitors are used in circuits compatible
with their ratings. Therefore, these capacitors do not need to be provided with an additional,
definable insulation level when the capacitor casing is acting as Basic or Operational insulation.
(Y1 capacitors may be accepted as Reinforced insulation also.)
Capacitor casings of X1, Y1, and Y2 capacitors Recognized to UL 1414 under Across-The-Line
Capacitors, Antenna Coupling and Line-By-Pass Components (FOWX2) may also be accepted
as Operational or Basic insulation when the capacitors are used in circuits compatible with their
ratings. Therefore, these components do not need to be provided with an additional, definable insulation level, such as Recognized Component – Tubing, when adequate clearances are not
provided between the capacitor casing and another component or an earthed dead metal part.
(Y1 capacitors may be accepted as Reinforced insulation also.)
Capacitor casings of capacitors Recognized to UL 1283 under Electromagnetic Interference
Filters (FOKY2) also may be accepted as Operational or Basic Insulation when the capacitors
are used in circuits compatible with their ratings. Therefore, these components do not need to
be provided with an additional, definable insulation level when the capacitor casing is acting as
basic or operational insulation.
RATIONALE:
Under IEC 60384-14, X1, X2, X3, Y2, and Y3 capacitors are subjected to a minimum Electric
Strength Test of 2000 V rms between live parts and case. Y1 capacitors are subjected to a 4000
V test. (Y4 are only subjected to a 900 V test).
For Recognized Component FOWX2 capacitors, UL 1414 now covers X1, Y1 and Y2 capacitors,
and the minimum Electric Strength Test is 2000 V between live parts and case. Y1 capacitors
are subjected to a 4000 V test.
For Recognized Component FOKY2 capacitors, UL 1283 requires the insulation between live
parts and casing is required to pass a 2Vr+1500V (Vrating =< 250V) electric strength test.
Additionally, the case is required to be V-2 or less flammable (or equivalent), and meet UL 746C
(or generic) insulation requirements.
