Note
The rated motor current is extremely important when selecting a soft starter.
Refer to the information about selecting soft starters in chapter Configuration (Page 77).
Conditions
for normal starting (CLASS 10):
Max. ramp-up time 20 s, current limiting 300 %, 5 starts / hour, ON time 30 %, standal
one
assembly, max. installation altitude 1000 m / 3280 ft, ambient temperature kW 40 °C / 104°.
A larger model may need to be selected if other conditions and constraints apply or for a
higher starting frequency. We recommend using the "Win-Soft Starter" selection and
simulation software. For information about the rated currents for ambient temperatures > 40
°C, refer to chapter 3RW40 24, 26, 27, 28 power electronics (Page 156).
