Fuse configurations
with SITOR 3NE1..-0
The following table specifies the fuse configuration (coordination type 2) for
3RW30/31 with SITOR fuses 3NE1..-0 (short-circuit and line protection);
max. short-circuit current 50 kA:
Table 8-18: Fuse configurations (SITOR)
1)Fuse coordination for max. 400 V
2)Fuse coordination for max. 500 V
3)Fuse coordination with all-range fuses not possible;
pure semiconductor protection fuses plus circuit breakers
can be used instead (see following table)
