Infeed systems for 3RA6

SIRIUS Innovations Supplement 2011

Infeed

The 3-phase infeed is available as an infeed with screw connec-

tion (4-2 AWG up to 63 A or 0-2/0 AWG up to 100 A) and a an

infeed with spring-type connection (4-2 AWG up to 63 A).

The infeed with spring-type terminal can be attached to the left

side, as well as the right side, of an expansion module.

The screw terminal infeeds are permanently fitted to the left side

of a 3-socket expansion module.

The infeeds with screw connection enable connection of the

main conductors (L1, L2, L3) either from above or from below.

The infeeds with screw connection come packaged with 1 end

cover, while the infeed with spring-type connection comes pack-

aged with 2 end covers.

Three-socket expansion modules

The expansion module with 3 sockets for compact starters is

available with screw connection and with spring-type

connection.

Expansion modules enable the infeed system to be expanded

and can be connected to each other in any number up to a max-

imum length of 1.2 meters.

Two expansion modules are held together with the help of

2 connecting 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 compact starters is used, the

compact starters (plug-in modules) are easily mounted and re-

moved even when live.

Optional possibilities:

• PE connection on motor starter side

• Outfeed for external auxiliary devices

• Connection to 3RV19 or 3RV29 infeed system

• Integration of SIRIUS 3RV1 motor starter protectors size 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-type connection (2 AWG) 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 tap-off

The PE tap-off is available with screw connection and spring-

type connection (10-8 AWG). It is snapped into the infeed sys-

tem from below.

Connecting plates

Two connecting plates are used to hold together 2 adjacent

expansion modules.

End covers

On the last expansion module of a row, the slot provided for the

expansion plug can be covered by inserting the end cover.

45 mm adapters for SIRIUS 3RV1 motor starter protectors

SIRIUS 3RV1 motor starter protectors size

S0 with screw connec-

tion can be fitted to the adapter, enabling them to be plugged

into the infeed system.

Terminal blocks

Using the terminal block, three phase power can be fed out of

the infeed system; this means that single-phase, two-phase and

three-phase components can also be integrated in the system.

If the end cover is removed, the terminal block can be inserted

into an expansion module.

Expansion plug for SIRIUS 3RV19 infeed systems

If the end cover is removed, the expansion plug for the SIRIUS

3RV19 infeed system can be inserted into an expansion module.

It connects the infeed system for 3RA6 compact starters with the

SIRIUS 3RV19 infeed system.

Maximum rated operational current

The following maximum rated operational currents apply for the

components of the infeed system for 3RA6:

When several expansion modules are mounted side by side, the

maximum rated operational current from the 2nd expansion

module to the end of the row is 63 A.

Proposal for upstream short-circuit protection devices

The following short-circuit data apply for the components of the

infeed system for 3RA6 compact starters:

To prevent the possibility of short-circuits, the cables on the terminal block

must be installed so that they are short-circuit proof according to

EN 60439-1 Section 7.5.5.1.2.
