H02K 11/20 for measuring, monitoring, testing, protecting or switching (rectifiers H02K11/04; power electronics H02K11/33)
Introduced: January 2016
Title
Titles differ between systems:
IPC: for measuring, monitoring, testing, protecting or switching
CPC: for measuring, monitoring, testing, protecting or switching (rectifiers H02K11/04; power electronics H02K11/33)
Full Title
Full titles differ between systems:
Structural association of dynamo-electric machines with electric components or with devices for shielding, monitoring or protection > for measuring, monitoring, testing, protecting or switching
Structural association of dynamo-electric machines with electric components or with devices for shielding, monitoring or protection (casings, enclosures or supports H02K5/00) > for measuring, monitoring, testing, protecting or switching (rectifiers H02K11/04; power electronics H02K11/33)
IPC and CPC are identically structured here. All 6 subcodes exist in both systems.
3 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 2016.
