10.4.4 Switching frequency filter capacitors
The capacitors specified below are suitable for operation at any switching frequency. These being sized for operation at 3kHz, however, operation
above 3kHz is possible with the capacitors being more effective.

Switching frequency filter capacitor MCB
The 3-phase switching frequency filter capacitors can absorb harmonics
from the supply or notching currents from DC drives which can result in
spurious tripping of the MCB. Therefore considerations must be made to
the supply when sizing the MCB, if these are present at high levels. In
this situation consult the drive supplier for advice.

The 3-phase switching frequency filter capacitors are
situated on the input of the regen system. As a result the
capacitor can also absorb harmonics if present from the
supply, and in worst case conditions result in the capacitors
running hot or even failure.
An MCB should be fitted between the AC supply and the 3-
phase switching frequency filter capacitor. This is to protect
the capacitor and the wiring to the mains busbar from
damage by faults or overloads.
