3RW30
General data
6
1)
The rated motor current (specified on the motor's name plate) should at
least amount to the specified percentage of the SIRIUS soft starter unit's
rated operational current
I
e
.
2)
If this value is exceeded, problems with line capacities may arise, which
can result in false firing.
