Can the main breaker in EZM31600GCBC be adjusted down to 1400A?

Issue:
Adjustable trip range

Product Line:
EZM Main Breaker

Environment:
1600A Main Breaker

Cause:
Different long time trip setting required

Resolution:
The RGF36160U31A main breaker can be adjusted, but has an A trip unit with .8 and .9 mulitpliers, which would adjust to 1280A or 1440A as the closest values to 1400A. The closest you could get to 1400A would be 1408A by changing the A trip unit out with a B trip unit and adjusting to .88 multiplier. The B trip unit is part number S48819.
