■ Overview (continued)
SIRIUS 3RA6 compact feeders
The SIRIUS 3RA6 compact feeders are universal motor feeders
according to IEC 60947-6-2. As control and protective switching
devices (CPS) they can connect, convey and disconnect the
thermal, dynamic and electrical loads from short-circuit currents
up to
I
q
= 53 kA, i.e. they are practically weld-free. They com-
bine the functions of a motor starter protector, a contactor and a
solid-state overload relay in one enclosure. Direct-on-line start-
ers with 45 mm width and reversing starters with 90 mm width
are available as versions.
The reversing starter version comes with not only an internal
electrical interlock but also with a mechanical interlock
to prevent
simultaneous actuation of both directions of rotation.
The compact feeders have isolating features in accordance with
IEC 60947.2 and can be used as disconnector units (main con-
trol switch according to EN 60204 or DIN VDE 0113). Isolation is
effected by moving the handle into the "OFF" position;
disconnection by means of the control contacts is not enough.
3RA6 fuseless compact feeders are supplied for 5 different
current setting ranges. The 3RA61 and 3RA62 have 3 control
voltage ranges (AC/DC), the 3RA64 and 3RA65 have one control
voltage range (DC):
Note:
The 3RA1 load feeders can be used for fuseless load feeders
> 32 A up to 100 A.
The SENTRON 3VL circuit breakers and the SIRIUS 3RT contac-
tors can be used for fuseless load feeders >100 A.
Operating conditions
The SIRIUS 3RA6 compact feeders are suitable for use in any
climate. They are intended for use in enclosed rooms in which no
severe operating conditions (such as dust, caustic vapors, haz-
ardous gases) prevail. Suitable covers must be provided for
installation in
dusty and damp locations .
The SIRIUS compact feeders are generally designed to degree
of protection IP20. The permissible ambient temperature during
operation is -20 to +60 °C.
The rated short-circuit current I
CS
according to IEC 60947-6-2 is
53 kA at 400 V.
Note:
The maximum permissible short-circuit currents of the device
versions for the various forms of power supply and voltages
are available on request from Technical Assistance:

Overload tripping times
The overload tripping time can be set on the device to normal
starting conditions (CLASS 10) and to heavy starting conditions
(CLASS 20). As the breaker mechanism still remains closed after
an overload, resetting is possible by either local manual reset or
auto reset after 3 minutes cooling time.
With autoreset there is no need to open the control cabinet.
Diagnostics options
The compact feeder provides the following diagnostics options:
• With LEDs
- Connection to the control voltage
- Position of the main contacts
• With mechanical indication
- Tripping due to overload
- Tripping due to short circuit
- Tripping due to malfunction (end of service life reached be-
cause of worn switching contacts or a worn switching mech-
anism or faults in the control electronics)
These states can also be evaluated in the higher-level control
system:
• With parallel wiring using the integrated auxiliary and signal-
ing switches of the compact starter
• With AS-Interface or IO-Link in even greater detail using the
respective communication interface
Four complement versions for 3RA6 compact feeders
• For standard mounting rail or screw fixing:
basic version including 1 pair of main circuit terminals and
1 pair of control circuit terminals
• For standard mounting rail or screw fixing when using the
AS-i add-on module:
without control circuit terminals because the AS-i add-on
module is plugged on instead
• For use with the infeed system for 3RA6:
without main circuit terminals because they are supplied with
the infeed system and the expansion modules
• For use with the infeed system for 3RA6 and
the AS-i add-on module: without terminal complement
(also for reordering when replacing the compact starter)
• The control circuit terminals are always required by the com-
pact starters for IO-Link; the main circuit terminals depend on
the use of the infeed system.
More components of the 3RA6
Already integrated in the 3RA61/3RA62 – and connectable using
the two 6-pole removable control circuit terminals – in addition to
the control supply voltage are the signaling contacts "overload"
(1 CO) and "short circuit / malfunction" (1 NO). The 3RA61 has
two auxiliary contacts (1 NO + 1 NC) for indicating the position
of the main contacts. Unlike the 3RA61 direct-on-line starter, the
3RA62 reversing starter has one auxiliary contact (1 NO) per di-
rection of rotation per main contact.
