Type NS-B, a revised type designation from our
previous type designation of NS for “Class I
Equipment,” is recognized and classified as Sub-
Class Y2 capacitor according to IEC384-14 2nd Ed.
by European Safety Regulations.
The Type NS-B is recognized by UL and CSA
(UL1414/250 VAC and CSA C22.2 No.1).
