200 to 460 V with screw terminals:
Standard delivery time SD = 1 day
Soft starter

400 to 600 V with screw terminals:
Standard delivery time RL = 2 days
2)
Main circuit connection: busbar connection.
3)
Control by way of the internal 24 V DC supply and direct control via PLC
possible.
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 (side-by-side,
see manual
)
In case of additional requirements, it may be necessary to
choose a larger device. In some cases, however, the safety
margins taken into account in the selection also permit the listed
units to be used in boundary conditions which are slightly more
demanding. Detailed technical information for a configuration
which is tailored exactly to the application,
see manual
.
For dimensioning soft starters under other boundary conditions,
also for heavy starting up to CLASS 20, we recommend our
