1) The SIRIUS 3RW301.. soft starters cannot be operated
with a fan.

Dimensioning of the
circuit breaker
The frame size selected for the circuit breaker should be large enough so
that the current value calculated can just be set.
In the event of current values that are lower than can be set for the speci-
fied circuit breaker, the next smaller circuit breaker must be used.
