Selection and ordering data
1)
3RW442. to 3RW444. soft starters with screw terminals:
standard delivery time SD = 1 day.
2)
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 SIRIUS 3RW44 solid-state
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 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
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 30, we recommend our
