1 3RA3 Reversing Contactor Assemblies SIRIUS 3R Overview The 3RA3 reversing contactor assemblies can be ordered as follows:, open type, with mechanical and electrical interlock. ) As components for customer assembly. There is also a range of accessories (auxiliary switch blocks, surge suppressors, etc.) that must be ordered separately. For overload relays for motor protection, see Part. The contactor assemblies have screw connections and are available for screwing or snapping onto 3 mm standard mounting rails. The s and u approvals only apply to the complete contactor assemblies and not to the components for customer assembly.

They are safe from touch to DIN VDE 0 Part 00. The contactor assemblies each consist of two contactors with identical ratings and one NC contact in the basic unit. The contactors are mechanically and electrically interlocked (NC contact interlock). The main and control circuits are wired according to the circuit diagrams on page 3/9. For motor protection, either 3RU overload relays for direct mounting or individual mounting or thermistor motor protection tripping units must be ordered separately. Components for customer assembly Installation kits for all sizes are available for customer assembly of reversing contactor assemblies. Contactors, overload relays, the mechanical interlock (as of size S0) and - for momentary-contact operation - auxiliary switch blocks for latching must be ordered separately. The following points should be noted: Size S00: For maintained-contact operation: use contactors with an NC contact in the basic unit for the electrical interlock. For momentary-contact operation: use contactors with an NC contact in the basic unit for the electrical interlock; in addition, an auxiliary switch block with at least one NO contact for latching is required per contactor. Sizes S0 to S3: For maintained-contact operation: the contactors have no auxiliary contact in the basic unit; NC contacts for the electrical interlock are therefore integrated in the mechanical interlock that can be mounted on the side of each contactor (one contact each for the left and right-hand contactors). For momentary-contact operation: the electrical interlock is the same as for maintained-contact operation; in addition, an auxiliary switch with one NO contact for latching is required per contactor. This contact can be snapped onto the top of the contactors. Alternatively, auxiliary switch blocks mounted on the side can be used; they must be fitted onto the outside of each contactor. If the front-mounted mechanical interlock is used for size S0 to S3 contactors, two location holes for single-pole auxiliary switch blocks are provided on the front of each S0 or S contactor, while three additional, single-pole auxiliary switch blocks can be snapped onto S3 contactors. The maximum auxiliary switch complements per contactor stated on page 3/ must not be exceeded. When size S and S3 contactors are combined with a frontmounted mechanical interlock, the 3RA9 33-B and 3RA9 3-B installation kits cannot be used. For accessories, see page 3/. For technical data, see page 3/8. For circuit diagrams, see page 3/9. For dimensions, see page 3/8. ) An additional dead interval of 0 ms is necessary on reversing at voltages > 00 V. Mode of operation The operating times of the individual 3RT0 contactors are rated in such a way that no overlapping of the contact making and the arcing time between two contactors can occur on reversing, providing they are interlocked via their auxiliary switches (NC contact interlock) and the operating mechanisms. An additional dead interval of 0 ms is necessary on reversing if the individual contactors are used at voltages > 00 V. The operating times of the individual contactors are not affected by the mechanical interlock. Surge suppression All contactor assemblies can be fitted with RC elements or varistors for damping opening surges in the coil. As with the individual contactors, the surge suppressors can either be plugged onto the top of the contactors (S00) or fitted onto the coil terminals on the top or bottom (S0 to S3). 3/0 Siemens NS K 000

6 SIRIUS 3R 3RA Contactor Assemblies for Star-Delta Starting Overview The 3RA contactor assemblies for star-delta starting can be ordered as follows:, open type, with electrical interlock, dead interval of up to 0 s on reversing (size S00 with electrical and mechanical interlocks). As components for customer assembly. A dead interval of 0 ms on reversing is already integrated in the time-delay relay function. There is also a range of accessories (auxiliary switch blocks, surge suppressors, etc.) that must be ordered separately. For overload relays for motor protection, see Part. The contactor assemblies have screw connections and are available for screwing or snapping onto 3 mm standard mounting rails. 3RA contactor assemblies have one unassigned NO contact, which is mounted onto the front of contactor K3. A solid-state time-delay auxiliary switch block is snapped onto the front of the complete contactor assemblies, size S00 up to. kw, while a time-delay relay is mounted onto the side of sizes S0 to S3,. kw to kw.

On the star step the motors can carry approximately 0 % (class KL ) or 30 % (class KL 0) of their rated torque; the starting torque is approximately / 3 of that during direct on-line starting. The starting current is approximately to. times the rated motor current. The changeover from star to delta must not be effected until the motor has run up to rated speed. Drives which require this changeover to be performed earlier are unsuitable for stardelta starting. The ratings given in the above table are only applicable to motors with a starting current ratio of I A 8. I N and using either a 3RT9 -G or 3RT9 -G solid-state time-delay auxiliary switch block with a star-delta function or a PU 0 stardelta time-delay relay with a dead interval of approximately 0 ms on reversing. For the circuit diagrams for the main and control circuits, see page 3/93. The size selected for the installation kits for stardelta starting is determined by the line contactor. Design Components for customer assembly Installation kits with wiring connectors and, if necessary, mechanical connectors are available for contactor assemblies for star-delta starting. Contactors, overload relays, star-delta time-delay relays and auxiliary switches for the electrical interlock if required also feeder terminals, mechanical interlocks ) and baseplates must be ordered separately. The wiring installation kits for sizes S00 and S0 contain the top and bottom main conducting path connections between the line and delta contactors (top) and between the delta and star contactors (bottom). In the case of sizes S and S3 only the bottom main conducting path connection between the delta and star contactors is included in the wiring connector, owing to the larger conductor cross-section at the infeed. Motor protection Overload relays or thermistor motor protection tripping units can be used for overload protection. The overload relay can be either mounted onto the line contactor or separately fitted. It must be set to 0.8 times the rated motor current. Surge suppression All contactor assemblies can be fitted with RC elements, varistors or diode assemblies for damping opening surges in the coil. As with the individual contactors, the surge suppressors can either be plugged onto the top of the contactors (S00) or fitted onto the coil terminals on the top or bottom (S0 to S3).
