Combination with other sizes
The infeed system for 3RA6 can be connected to the SIRIUS 3RV19 infeed system using the
extension connector for 3RV19 (3RA6890-1AA). SIRIUS size S0 circuit breakers
(max. 12.5 A / 400 V; I
CU
< 53 kA) can be installed on the infeed system for 3RA6 using the
45 mm adapter for the infeed system for 3RA6 (3RA6890-0BA).
For additional information on combining the equipment with other sizes, please refer
to "
Configuration (Page 25)".
12.3.2 Coding the SIRIUS infeed system for 3RA6
The infeed system for compact starters can be locked by disabling the slots with a padlock
(shackle diameter 3.5 - 4.5 mm). Simply attach a padlock to the fixture on the infeed system.
Figure 12-2 Locking the SIRIUS infeed system for 3RA6 for compact starters
Alternatively, the infeed system for 3RA6 can be coded to only allow installation of compact
starters with a defined maximum rated current. This function prevents compact starters being
installed on the infeed system if their current setting range is too high, thereby eliminating the
problem of infeed system current overload, for example.
The infeed system for 3RA6 can be locked against compact starters with the following
current setting ranges:
● 3 to 12 A
● 8 to 32 A
● 3 to 12 A and 8 to 32 A
Procedure
Coding is achieved by means of cylindrical pins (DIN EN ISO 8734-2x8). The cylindrical pins
are inserted into special holes in the infeed system's base carrier. The cylindrical pins are
used as spacers and prevent compact starters from being snapped onto certain slots of the
infeed system.
