Fuseless configuration
The following table specifies the components of the fuseless configuration
(coordination type 1) for 3RW30/31; short-circuit current of 50 kA/400 V:
Table 8-20: Motor feeder: fuseless configuration
1) The selection and setting of the circuit breaker is based on the rated cur-
rent for the motor
2) 50 mm clearance is required above and below between the 3RW and
grounded parts
