Rated back-to-back capacitor bank breaking current for special purpose switches (Ibb):
The rated back-to-back capacitor bank breaking current is the maximum capacitor bank current that a special purpose switch shall be capable of breaking at its rated voltage with one or more capacitor banks connected on the supply side of the switch adjacent to the bank being switched.
Rated back-to-back capacitor bank inrush making current for special purpose switches (Iin):
The rated back-to-back capacitor bank inrush making current is the peak value of the current that a special purpose switch shall be capable of making at its rated voltage and with a frequency of the inrush current appropriate
to the service conditions.
The assignment of a rated back-to-back capacitor bank inrush making current is mandatory for switches that have a rated back-to-back capacitor bank breaking current.
NOTE: The frequency of the inrush current for back-to-back capacitor banks may be in the range of 2 kHz to 30 kHz. The frequency and magnitude of the inrush current are dependent upon the size and configuration of the capacitor bank being switched, the capacitor bank already connected to the supply side of the switch and the inclusion of limiting impedances, if any.
The switch is not necessarily rated to break the inrush making current produced by the back-to-back capacitor bank installation.
