Fuse configurations
with SITOR 3NE8
The following table specifies the fuse configuration (coordination type 2) for
3RW30/31 with SITOR fuses 3NE8 (semiconductor protection is provided by
the fuse; line protection and overload protection are provided by the circuit
breaker); max. short-circuit current 50 kA/400 V:
Table 8-19: Fuse configurations (SITOR)
1) Coordination with pure semiconductor protection fuses is not possible;
all-range fuses 3NE1..-0 can be used (see the table above)
2) The selection and setting of the circuit breaker is based on the rated cur-
rent for the motor
3) Note the unit of quantity
If the motor is to be configured to meet UL requirements, the order number
of the fuse must be specified (3NE80..-1).
