For Operation in the Control Cabinet 3RW Soft Starters © Siemens AG 2009 3RW30 for standard applications Fuse assignment The type of coordination to which the motor feeder with soft starter is mounted depends on the application-specific require- ments. Normally, fuseless mounting (combination of motor starter protector/circuit breaker and soft starter) is sufficient. If type of coordination "2" is to be fulfilled, semiconductor fuses must be fitted in the motor feeder. 6 1) The rated motor current must be considered when selecting the devices. 2) The types of coordination are explained in more detail under "3RA1 Fuseless Load Feeders".
1) The types of coordination are explained in more detail under "3RA1 Fuse- breaker/fuse), not to any additional components in the feeder. 2) I q = 50 kA at 400 V. 3) 3NA3 805-1 (LV HRC00), 5SB2 61 (DIAZED), 5SE2 201-6 (NEOZED). less Load Feeders".
