Other topologies are relatively easy to ...
The maximum allowed ripple current and transient load may be very specific to the capacitor type. Some capacitor technologies may define ripple current and maximum surge current only, while dI/dt is considered to be covered by its "maximum surge current limitation".

Then round up to the next standard 3ph kVA rating as found in Section 14 of SquareD/Schneider Electric Catalog, Digest 178.
The maximum allowable ripple current is based on the capacitor''s power dissipation capability (as function of construction and case size) and expressed by maximum "self-heating" during the operation under ripple …
Capacitors for AC applications are primarily film capacitors, metallized paper capacitors, ceramic capacitors and bipolar electrolytic capacitors. The rated AC load for an AC capacitor is the maximum sinusoidal effective AC current (rms) which may be applied continuously to a capacitor within the specified temperature range.
And hence, when circuit breaker opens at current zero, voltage across the breaker contact is maximum. Whereas, in case of resistive load both current & voltage becomes zero at same time. Therefore, switching such type of inductive loads is critical. ... people are calling capacitor bank as capacitive load. Well, I think, capacitor bank …

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
