1) If the "Combined braking" stopping function is selected, no braking contactor is required.
If the "DC braking" function is selected, a braking contactor must be additionally used (for type, see table).
The "DC braking" function is recommended for applications with larger centrifugal masses (J
load
> J
motor
).
2) Additional K4 auxiliary relay:
LZX:RT4A4T30 (3RW44 soft starter with 230 V AC rated control supply voltage),
LZX:RT4A4S15 (3RW44 soft starter with 115 V AC rated control supply voltage).
3) "Utilization class 1" refers to the soft starter in combination with the protective device listed (circuit breaker/fuse), not to
other components in the branch. For utilization class, see page 10-20.
