Fused configuration
The following table specifies the components of the fused configuration
(coordination type 1) for 3RW30/31; short-circuit current of 50 kA/400 V:
Table 8-21: Motor feeder: fused configuration
1) The selection and setting of the overload relay is based on the rated cur-
rent for the motor
2) Short-circuit current of 50 kA to max. 400 V
3) Short-circuit current of 50 kA to max. 500 V
4) 50 mm clearance is required above and below between the 3RW and
grounded parts
