H10D 48/30 Devices controlled by electric currents or voltages
Introduced: January 2025
Full Title
Full titles differ between systems:
IPC:
Individual devices not covered by groups > Devices controlled by electric currents or voltages
CPC:
Individual devices not covered by groups H10D1/00 - H10D44/00 > Devices controlled by electric currents or voltages
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
IPC defines codes here since 2025.
