Power Series Output Rating Curves
Fan Cooled
All curves are at 100% on with 90°C rated load wire and line wire connected. Note that each
chart is slightly different on the amperage scale. The safe operating region is from 1 amp up
to the specific curve for the output amperage code selected. For example: F25 Single-Phase is
rated up to 200 amps at 50°C; F30 Single-Phase is rated for 250 amps at 50°C. See page 2.6
for Natural Convection Cooled output rating curves.
