■ Overview (continued)
$ Infeed
The 3-phase infeed is available with screw connection
(25/35 mm
2
up to 63 A or 50/70 mm
2
up to 100 A) and spring-
load connection (25/35 mm
2
up to 63 A).
The infeed with spring-loaded terminal can be fitted on the left
as well on as the right to an expansion module.
The infeed with screw terminal
is supplied only with a 3-socket
expansion module and permanently fitted on the left side
.
The infeeds with screw connection enable connection of the
main conductors (L1, L2, L3) either from above or from below.
The infeed with screw connection is supplied complete with
1 end cover, the infeed with spring-load connection complete
with 2 end covers.
% Three-socket expansion module
The expansion module with 3 sockets for compact feeders is
available with screw connection and with spring-loaded connec-
tion.
Expansion modules enable the infeed system to be expanded
and can be fitted to each other in any number.
Two expansion modules are held together with the help of 2 con-
necting plates and 1 expansion plug. These assembly parts are
included in the scope of supply of the respective expansion
module.
When the infeed system for 3RA6 is used, the compact feeders
(plug-in modules) are easily mounted and removed even when
live.
Optional possibilities:
• PE connection on motor outgoing side
• Outfeed for external auxiliary devices
• Connection to 3RV19 infeed system
• Integration of SIRIUS motor starter protectors size S00 and S0
(using 3RA68 90-0BA adapter)
& Two-socket expansion modules
If only 2 instead of 3 additional sockets are required, then the
2-socket expansion module is the right choice. It has the same
functionality as the 3-socket expansion module.
( Expansion plug
Two expansion modules can be connected together using the
expansion plug. Flexible expansion of the infeed system is thus
possible.
) PE infeeds
This module enables a PE cable to be connected.
The PE infeed can be ordered with screw connection and
spring-loaded connection (35 mm
2
) and can be fitted on the
right or left to the expansion block.
* PE expansion plug
The PE expansion plug is inserted from below and enables two
PE bars to be connected.
+ PE pick-off
The PE pick-off is available with screw connection and spring-
loaded connection (6/10 mm
2
). It is snapped into the infeed
system from below.
, Connecting plates
Two connecting plates are used to hold together
2 expansion modules.
- End covers
On the last expansion module of a row, the socket provided for
the expansion plug can be covered by inserting the end cover.
. 45 mm adapters for SIRIUS motor starter protectors
SIRIUS motor starter protectors size S0 with screw connection
can be fitted to the adapter, enabling them to be plugged into
the infeed system.
Terminal blocks
Using the terminal block the 3 phases can be fed out of the
system; this means that single-phase, 2-phase and 3-phase
components can also be integrated in the system.
After the end cover is pulled out, the terminal block can be
plugged onto an expansion module.
Expansion plug for SIRIUS 3RV19 infeed systems
After the end cover is pulled out, the expansion plug for the
SIRIUS 3RV19 infeed system can be plugged onto an expansion
module. It connects the infeed system for 3RA6 with the
SIRIUS 3RV19 infeed system.
