SIRIUS 3RW Soft Starters
3RW44 for High Feature Applications
General data
6
1)
The type of coordination "2" refers to soft starters in combination with the
stipulated protective device (motor starter protector/fuse), not to any
additional components in the feeder.
2)
If the ramp-down function "Combined braking" is selected, no braking
contactor is required. A braking contactor must be additionally used if the
"DC braking" function is selected (for type,
see table
).
For applications with greater centrifugal mass (
J
Load
>
J
Motor
), the function
"DC braking" is recommended.
3)
Additional auxiliary relay K4:
LZS:RT4A4T30
(3RW44 soft starter with rated control supply voltage 230 V AC),
LZS:RT4A4S15
(3RW44 soft starter with rated control supply voltage 115 V AC).
Inline circuit fused version with 3NE or 3NC SITOR semiconductor fuse
(semiconductor protection by fuse, line and overload protection by motor starter protector)
