In “Continuous duty cycle” current.
IS6-40% Current that, in an intermittent duty cycle S6 with 10 minute
cycle, circulates for 4 minutes with load (the other 6 minutes operates
without load); in other words with magnetizing current = 0.7 x
rated current In).
Imax Maximum peak current.
See load duty cycles.
Note. The values of these currents are given in RMS.
