Selection and ordering data
1)
Soft starter
U
e
200 to 480 V with screw terminals:
standard delivery time SD = 1 day
2)
Main connection from size S2: screw terminals.
Note:
The listed motor ratings are rough guide values. The soft starter
should always be designed on the basis of the required rated
operational current of the motor.
The 3RW40 soft starters are designed for easy starting
conditions. The selection and ordering data were determined for
the following boundary conditions
(see also the notes on
page 6/6)
:
•
Maximum starting time in s: 10
•
Maximum starting current in % of motor current
I
e
: 300
•
Maximum number of starts per hour in 1/h: 5
•
Stand-alone installation without auxiliary fan
(side-by-side,
see manual
, increased switching frequency
possible using auxiliary fans)
For dimensioning soft starters under other boundary conditions,
also for heavy starting up to CLASS 20, we recommend our
Simulation Tool for Soft Starters (STS):
