Final selection of the primary section
For the example considered here, for a peak load motor, primary section 1FN3150-4WC00-
0BA1 is suitable, and for a continuous load motors, primary section 1FN3150-4NB80-0BA1.
Which primary section is best suited to the specified duty cycle can be derived from the
following summary:
