DTSS = Double Throw Safety Switches  
Max. = Maximum
Ampere Ratings = Amp


There are two voltage ratings for DTSS, some of the switches are rated up to 240V ac Max. and 250V dc max. Then some of the DTSS are rated up to 600V ac Max. and 600V dc Max. 
SEE THE CURRENT SCHNEIDER ELECTRIC DIGEST AND/OR INDIVIDUAL CAD DRAWING OF EACH CATALOG NUMBER TO SEE THE MAXIMUM VOLTAGE RATING FOR THAT SWITCH.

Below are the Max. Amp ratings in the Fusible and Non-fusible versions: 
1) The Fusible DTSS are available in ampere ratings from 30A through 100A Max. Prefix Catalog numbers of DT(Series F ONLY)
2) The Non-fusible DTSS are available with ampere ratings from 30A through 600A Max. Prefix Catalog numbers DTU, Types 82000 and 92000.
SEE CURRENT ON-LINE DIGEST FOR CATALOG NUMBERS.

NOTES:
1) Square D/Schneider Electric is no longer offering ANY 400amp Max. DTSS, consider using the 600amp Max. BUT first verify the physical size by obtaining the CAD drawing and the terminal lug data for the 600amp.
2) Square D/Schneider Electric does not offer any DTSS rated higher than 600amp. So there are NO, DTSS rated 800amp or 1200amp.
