Notes: For AR208S, AR212S, AR216S, AR208D, AR212D and AR216D it is assumed that main circuit terminals are of horizontal type at both the line and load sides. For other
types, it is assumed that main circuit terminals are of vertical type at both the line and load sides. The above values may vary depending on the switchboard configuration.
