Frame-2 : 400 - 3200A N/N08/N10/S/H & 4000A S/H
Note: Above table is based on extensive study of popular bus-bar sizes used to terminate Air Circuit Breakers.
However other bus-bar sizes (in terms of thickness & width) can also be used to achieve bus-
Bar cross section recommended by IS & IEC. De-rating of switchgear depends upon various factors
Such as cross section area, orientation and material of bus bar, healthiness of bus-bar joints,
panel construction, and ventilation, etc.
*Not as per standard but generally followed
