© Siemens AG 2008 3RA6 Fuseless Compact Starters Catalog News LV 1 N • April 2008 SIRIUS www.siemens.com/lowvoltage © Siemens AG 2008 3RA6 Fuseless Compact Starters General data ■ Overview 3RA6 fuseless compact starters and infeed system for 3RA6 Note: Integrated functionality For fast orientation with regard to the type of connection, different colored backgrounds are assigned to the Order No. and the price in the selection and ordering data: The SIRIUS 3RA6 compact starters are a generation of innovative load feeders with the integrated functionality of a circuit breaker, contactor and solid-state overload relay. In addition, various functions of optional mountable accessories (auxiliary switches, surge suppressors) are already integrated in the SIRIUS compact starter. Application The SIRIUS compact starters can be used wherever standard induction motors up to 32 A (approx. 15 kW/400 V) are directly started. Low equipment variance Thanks to wide setting ranges for the rated current and wide voltage ranges, the equipment variance is greatly reduced compared to conventional load feeders. • Products with screw connections appear on a green background. • Products with spring-loaded connections appear on an orange background. • Products with different connections on the incoming and outgoing side appear on a gray background. System configurator for engineering A free system configurator is available to reduce further the amount of engineering work for selecting the required compact starters and matching infeed. Very high operational safety Types of infeed for the 3RA6 fuseless compact starters No welding after a short-circuit release and defined shut-down when the end of service life is reached means that the SIRIUS compact starter achieves a very high level of operational safety otherwise possible only with considerable additional outlay. This sets it apart from devices with similar functionality. On the whole four different infeed possibilities are available: • Parallel wiring • Use of 3-phase busbars (combination with SIRIUS circuit breakers and SIRIUS contactors possible) • 8US busbar adapters • SIRIUS infeed system for 3RA6 Safe disconnection The auxiliary switches of the 3RA6 compact starters are designed as mirror contacts. It is thus possible to use the devices for safe disconnection, e.g. emergency-stops, up to Category 2 (EN954-1) and together with other redundancy switching devices up to Category 3 or 4. To comply with the clearance and creepage distances demanded according to UL508 there are the following infeed possibilities: Type of infeed Feeder terminal (according to UL 508, type E) Order No. Parallel wiring Terminal for "Self-Protected Combination Motor Controller (Type E)" 3RV19 28-1H 3-phase busbars 3-phase infeed terminal 3RV19 25-5EB for constructing "Type E Starters", UL 508 Infeed system for 3RA6 Infeed on left, 50/70 mm2, screw terminal with 3 sockets, outgoing terminal with screw/springloaded connections, including PE bar 6 Communications integration through AS-Interface To enable communications integration through AS-Interface there is an AS-i add-on module (also available as a version with two local inputs for safe disconnection) which can be mounted instead of the control circuit terminals on the SIRIUS compact starter. The design of the AS-i add-on module permits a group of up to 62 feeders with a total of four cables to be connected to the control system. This reduces wiring work considerably compared to the parallel wiring method. Permanent wiring / easy replacement Using the SIRIUS infeed system for 3RA6 it is possible to carry out the wiring in advance without a compact starter needing to be connected. A compact starter is very easily replaced simply by pulling it out of the device without disconnecting the wiring. Even with screw connections or mounting on a standard mounting rail there is no need to disconnect any wiring (on account of the removable main and control circuit terminals) in order to replace a compact starter. Consistent solution from the infeed to the motor feeder 3RA68 13-8AB (screw connection), 3RA68 13-8AC (spring-type connection) SIRIUS 3RA6 compact starters The SIRIUS 3RA6 compact starters are universal motor feeders according to IEC/EN 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 Iq = 53 kA, i.e. they are practically weld-free. They combine the functions of a circuit breaker, a contactor and a solid-state overload relay in a single enclosure and can be used wherever standard induction motors up to 32 A (up to approx. 15 kW at 400 V AC) are started directly. Direct-on-line and reversing starters are available as variants. The SIRIUS infeed system for 3RA6 with integrated PE bar is offered as a user-friendly possibility of feeding in summation currents up to 100 A with a maximum conductor cross-section of 70 mm² and connecting the motor cable directly without additional intermediate terminals. 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. Screw and spring-loaded connections 3RA6 fuseless compact starters are available with 5 current setting ranges and 3 control voltage ranges: The SIRIUS compact starters and the SIRIUS infeed system for 3RA6 are available with screw and spring-type connections. 6/2 Siemens LV 1 N Load Feeders · 04/2008 © Siemens AG 2008 3RA6 Fuseless Compact Starters General data Overall width of reversing starter Current setting At 400 V AC for range induction motors up to mm mm A kW 45 90 0.1 ... 0.4 0.09 45 90 0.32 ... 1.25 0.37 45 90 1 ... 4 1.5 45 90 3 ... 12 5.5 45 90 8 ... 32 15 The 3 control voltage ranges are: • 24 V AC/DC • 42 ... 70 V AC/DC • 110 ... 240 V AC/DC Note: Up to 100 A the 3RA1 load feeders can be used for fuseless load feeders > 32 A.

The infeed system provides the possibility of completely prewiring the main circuit without a compact starter needing to be connected at the same time. As the result of the removable terminals in the main circuit, compact starters can be integrated in an infeed system in easy manner (without the use of tools). In addition, the integrated PE bar means it is optionally possible to connect the motor cable directly to the infeed system without additional intermediate terminals. The infeed system for 3RA6 compact starters is designed for summation currents up to 100 A with a maximum 70 mm² conductor cross-section on the feeder terminal block. The infeed system can be mounted on a standard mounting rail or flat surfaces. 2 1 3 4 5 9 11 8 NSB0_01878 6 6 12 7 10 $ Feeder terminal + PE pick-off % Three-socket expansion module , Connecting plates & Two-socket expansion module - End cover ( Expansion plug . 45 mm adapter for SIRIUS motor starter protector size S00/S0 ) PE infeed / 3RA61 direct-on-line starter * PE expansion plug 0 3RA62 reversing starter Siemens LV 1 N Load Feeders · 04/2008 6/11 © Siemens AG 2008 3RA6 Fuseless Compact Starters Infeed Systems Infeed systems for 3RA6 $ Infeed . 45 mm adapters for SIRIUS motor starter protectors The 3-phase infeed is available with screw connection (25/35 mm2 up to 63 A or 50/70 mm2 up to 100 A) and spring-loaded connection (25/35 mm2 up to 63 A).

The electronic trip units are permanently set to a value 13 times the maximum rated current and thus enable trouble-free starting of motors. Trip classes The trip classes of electronically delayed trip units are based on the tripping time (tA) at 7.2 times the set current in the cold state (excerpt from IEC 60947-4): CLASS 10: 4s < tA < 10 s CLASS 20: 6s < tA < 20 s (for heavy starting) The compact feeder must have tripped within this time! Disconnection due to malfunction The following malfunctions can be detected: • End of service life - Worn switching contacts (for electrical endurance see "Technical specifications") - Worn switching mechanisms (for mechanical endurance see "Technical specifications") • Faults in the control electronics Short-circuit protection If a short-circuit occurs, the short-circuit releases of the SIRIUS 3RA6 compact feeders isolate the faulty load feeder from the network and thus prevent further damage. The short-circuit releases are factory-set to 13 times the value of the maximum rated current In of the device. The SIRIUS compact feeders have a short-circuit breaking capacity of 50 kA at a voltage of 400 V AC. Higher short-circuit currents are not to be expected in practice. Overload relay function In the event of an overload, the compact feeder switches off without the breaker mechanism being opened. The overload trip can be signaled to the higher-level control system through an integrated signal switch (1 CO). The overload signal can be reset automatically or by means of a manual reset. The AS-i auxiliary voltage and the AS-i data line are installed on the AS-i add-on module easily and quickly without tools by means of two plug-in connector blocks with insulation displacement connection. The AS-i add-on module is equipped with the latest A/B technology and has an addressing socket onboard. An addressing unit can be ordered for addressing the AS-i add-on module. Bit assignment (see below) is similar to that for the SIRIUS motor starters, which means that the same programming can be used here. DI 0.0 Ready DI 0.1 Motor on DI 0.2 Group fault DI 0.3 Group warning DO 0.0 Motor on or motor clockwise DO 0.1 Motor counterclockwise A 24 V DC PELV power supply unit according to VDE 010 safety class III is required for the auxiliary voltage. The AS-i data line is supplied with voltage by means of an AS-i power supply unit and is controlled by means of the AS-i master. The AS-i add-on modules are available in the following two versions: • AS-i add-on modules for compact feeders • AS-i add-on modules for compact feeders with two local inputs for safe disconnection of the "clockwise rotation" or "counterclockwise rotation" outputs Integrated auxiliary switches The control circuit terminals of the SIRIUS 3RA6 compact feeders have the following connections: • A1/A2 for control voltage • "Overload" signal switch • "Fault" signal switch, e.g. "short-circuit" • Internal auxiliary switch for position of the main contacts (in case of direct-on-line starters: 1 NO + 1 NC with mirror contact to the main contact; in case of reversing starters: 2 NO) Siemens LV 1 N Load Feeders · 04/2008 6/19 6 The overload releases can be adjusted in accordance with the load current. © Siemens AG 2008 3RA6 Fuseless Compact Feeders 3RA61, 3RA62 Compact Feeders 3RA61 direct-on-line starters, 3RA62 reversing starters ■ Technical specifications Type Size Number of poles 3RA61 S0 3 3RA62 General data Device standard IEC/EN 60947-6-2 A A A A A 0.4 1.25 4 12 32 Permissible ambient temperature • During operation according to IEC/EN 60721-3-3 • For installation in SIRIUS infeed system for 3RA6 • During storage IEC / EN 60732-3-1 • During transport IEC / EN 60721-3-2 °C °C °C °C -20 ... +60, with restriction up to +70 -20 ... +40 -55 ... +80 -55 ... +80 Permissible rated current of the compact feeder, when several compact feeders are mounted side-by-side on a vertical standard mounting rail or in the infeed system for 3RA6 • For a control cabinet inside temperature of +40 °C • For a control cabinet inside temperature of +60 °C % % 100 80 Relative air humidity % 10 ... 90 Installation altitude m Up to 2000 above sea level without restriction Rated operational voltage Ue V 690 Rated frequency Hz 50/60 Rated insulation voltage Ui (degree of pollution 3) V 690 kV 6 Max. rated current In max (= max. rated operational current Ie) for the respective setting range 0.1 ... 0.4 A 0.32 ...1.25 A 1 ... 4 A 4 ... 12 A 8 ... 32 A 6 Rated impulse withstand voltage Uimp Trip class (CLASS) according to IEC 60947-4-1, EN 60947-4-1 (VDE 0660 Part 102) 10/20 Rated short-circuit current Iq at AC 50/60 Hz 400 V according to IEC 60947-4-1, EN kA 60947-4-1 (VDE 0660 Part 102) 50 kA Types of coordination according to IEC 60947-6-2, EN 60947-6-2 (VDE 0660 Part 102) 2 and in addition weld-free according to IEC 60947-6-2 Power loss Pv max of all main current paths Dependent on the rated current In (upper setting range) up to 0.4 A 0.32 ... 1.25 A 1 ... 4 A 3 ... 12 A 8 ... 32 A Compact feeder endurance • Mechanical endurance • Electrical endurance at Ie = 0.9 In Max. switching frequency AC-41 AC-43 AC-44 Drive losses Active power at 24 V • Up to 12 A • 8 ... 32 A at 42 ... 70 V AC/DC • Up to 12 A • 8 ... 32 A at 110 ... 240 V AC/DC • Up to 12 A • 8 ... 32 A mW mW W W W 2 19.1 0.2 0.7 2.3 Oper- 10 000 000 ating cycles Oper- 1 520 000 ating cycles 1/h 1/h 1/h 750 250 15 W W 2.7 2.95 W W 2.5 3.0 W W 3.4 3.8 Overload function Ratio of lower to upper current mark 1:4 Shock resistance (sine-wave pulse) a = 60 m/s² = 6g with 10 ms;
