3 Solid-State Switching Devices General data Overview SIRIUS SC solid-state switching devices Solid-state relays Solid-state contactors Function modules SIRIUS SC for almost unending activity Conventional electromechanical switching devices are often overtaxed by the rise in the number of switching operations. A high switching frequency results in frequent failure and short replacement cycles. However, this does not have to be the case, because with the latest generation of our SIRIUS SC solid-state switching devices we provide you with solid-state relays and contactors with a particularly long service life for almost unending activity even under the toughest conditions and under high mechanical load, but also in noise-sensitive areas. Proved time and again in service SIRIUS SC solid-state switching devices have become firmly established in industrial use. They are used above all in applications where loads are switched frequently mainly with resistive load controllers, with the control of electrical heat or the control of valves and motors in conveyor systems. In addition to its use in areas with high switching frequencies, thanks to its silent switching SIRIUS SC is also ideally suited to noise-sensitive areas such as offices or hospitals. The most reliable solution for any application Compared with mechanical switching devices, our SIRIUS SC solid-state switching devices stand out because of their considerably longer service life. Thanks to the high product quality, their switching is extremely precise, reliable and above all insusceptible to faults. With its variable connection methods and a wide spread of control voltages, the SIRIUS SC family is universally applicable. Depending on the individual requirements of the application, our modular switching devices can also be quite easily expanded by the addition of standardized function modules. Always on the sunny side with SIRIUS SC Because SIRIUS SC offers even more: The space-saving and compact side-by-side mounting ensures reliable operation up to an ambient temperature of +60 C. Thanks to fast configuration and the ease of installation and start-up, you save not only time but also expenses.

4 Solid-State Switching Devices General data Design There is no typical design of a load feeder with solid-state relays or solid-state contactors; instead, the great variety of connection systems and control voltages offers universal application opportunities. SIRIUS SC solid-state relays and solid-state contactors can be installed in fuseless or fused feeders, as required. There are special versions with which it is even possible to achieve short-circuit strength in a fuseless design. Maximum load integral One of the purposes of specifying the maximum load integral (I²t) is to determine the rating of the short-circuit protection. Only a large power semiconductor with a correspondingly high I²t value can be given appropriate protection against destruction from a short-circuit by means of a protective device matched to the application. However, SIRIUS SC is also characterized by the optimum matching of the thyristors (I²t value) with the rated currents. The rated currents specified on the devices according to EN were confirmed by extensive testing. Function You can find more information on the Internet at: Connection technique All SIRIUS SC solid-state switching devices are characterized by the great variety of connection methods. You can choose More information between the following connection techniques: Notes on integration in the load feeders Screw connection system The screw connection system is the standard among industrial controls. Open terminals and a plus-minus screw are just two features of this technology. Two conductors of up to 6 mm² can be connected in just one terminal. As a result, loads of up to 50 A can be connected. Spring-loaded connection system This innovative technology manages without any screw connection. This means that very high vibration resistance is achieved. Two conductors of up to 2.5 mm² can be connected to each terminal. As a result, loads of up to 20 A can be dealt with. Ring terminal end connection The ring terminal end connection is equipped with an M5 screw. Ring terminal ends of up to 25 mm² can be connected. In this way it is possible to connect even high powers with current intensities of up to 90 A safely. Finger-safety is provided in this case too with a special cover. Switching functions In order to guarantee an optimized control method for different loads, the functionality of our solid-state switching devices can be adapted accordingly. The Zero-point switching method has proved to be ideal for resistive loads, i.e. where the power semiconductor is activated at zero voltage. For inductive loads, on the other hand, for example in the case of valves, it is better to go with Instantaneous switching. By distributing the ON point over the entire sine curve of the mains voltage, disturbances are reduced to a minimum. Performance characteristics The performance of the solid-state switching devices is substantially determined by the type of power semiconductors used and the internal design. In the case of the SIRIUS SC solid-state contactors and solid-state relays, only thyristors are used in place of less powerful Triacs. Two of the most important features of thyristors are the blocking voltage and the maximum load integral: Blocking voltage Suitable filters can be ordered from EPCOS AG. Thyristors with a high blocking voltage can also be operated You can find more information on the Internet at: without difficulty in power systems with high interference voltages. Separate protective measures, such as a protective circuit with a varistor, are not necessary in most cases. With SIRIUS SC, for example, thyristors with 800 V blocking voltage are fitted for operation in power systems up to 230 V. Thyristors with up to 1600 V are used for power systems with higher voltages. The SIRIUS SC solid-state switching devices are very easy to integrate into the load feeders thanks to their industrial connection technology and design. Particular attention must however be paid to the circumstances of the installation and ambient conditions, as the performance of the solid-state switching devices is largely dependent on these. Depending on the version, certain restrictions must be observed. Detailed information, for example in relation to solidstate contactors about the minimum spacing and to solid-state relays about the choice of heat sink, is given in the product data sheets and the technical specifications in the AD Mall. Despite the rugged power semiconductors that are used, solidstate switching devices respond more sensitively to shortcircuits in the load feeder. Consequently, special precautions have to be taken against destruction, depending on the type of design. Siemens generally recommends using SITOR solid-state protection fuses. These fuses also provide protection against destruction in the event of a short-circuit even when the solid-state contactors and solid-state relays are fully utilized. Alternatively, if there is lower loading, protection can also be provided by standard fuses or miniature circuit-breakers. This protection is achieved by overdimensioning the solid-state switching devices accordingly. The technical specifications in the AD Mall and the product data sheets contain details both about the solid-state fuse protection itself and about use of the SIRIUS SC devices with conventional protection equipment. The SIRIUS SC solid-state switching devices are suitable for interference-free operation in industrial power systems without further measures. If they are used in public power systems, it may be necessary for conducted interference to be reduced by means of filters. This does not include the special solid-state contactors of type 3RF23..-.CA.. Low Noise. These comply with the class B limit values up to a rated current of 16 A. If other versions are used, and at currents of over 16 A, standard filters can be used in order to comply with the limit values. The decisive factors when it comes to selecting the filters are essentially the current loading and the other parameters (operational voltage, design type, etc.) in the load feeder. / Siemens LV 1 T 2006

5 Solid-State Relays General data Overview More information Solid-state relays Selecting solid-state relays SIRIUS SC solid-state relays are suitable for surface mounting When selecting solid-state relays, in addition to information on existing cooling surfaces. Installation is quick and easy, about the power system, the load and the ambient conditions it involving just two screws. The special technology of the power is also necessary to know details of the planned design. The semiconductor ensures there is excellent thermal contact with solid-state relays can only conform to their specific technical the heat sink. Depending on the nature of the heat sink, the specifications if they are mounted with appropriate care on an capacity reaches up to 88 A on resistive loads. The 3RF21 solidstate relays can be expanded with various function modules to recommended: adequately dimensioned heat sink. The following procedure is adapt them to individual applications. Determine the rated current of the load and the mains voltage The solid-state relays are available in 2 different widths: Select the relay design and choose a solid-state relay with 3RF21 solid-state relay with a width of 22.5 mm higher rated current than the load 3RF20 solid-state relay with a width of 5 mm Determine the thermal resistance of the proposed heat sink Check the correct relay size with the aid of the diagrams Version for resistive loads, Zero-point switching You can find more information on the Internet at: This standard version is often used for switching space heaters on and off. Version for inductive loads, Instantaneous switching In this version the solid-state contactor is specifically matched to inductive loads. Whether it is a matter of frequent actuation of the valves in a filling plant or starting and stopping small drives in packet distribution systems, operation is carried out safely and noiselessly.

16 Solid-State Contactors General data Overview The complete units consist of a solid-state relay plus optimized 3/N/PE 50 Hz 230/00 V heat sink, and are therefore ready to use. They offer defined rated currents to make selection as easy as possible. Depending L1 on the version, current intensities of up to 88 A are achieved. L2 Like all of our solid-state switching devices, one of their particular advantages is their compact and space-saving design. With L3 their insulated mounting foot they can easily be snapped onto a N standard mounting rail, or they can be mounted on carrier plates with fixing screws. This insulation enables them to be used in circuits with protective extra-low voltage (PELV) or safety extralow voltage (SELV) in building engineering. For other applications, such as for extended personal safety, the heat sink can be grounded through a screw connection. Version for resistive loads, Zero-point switching This standard version is often used for switching space heaters on and off. Version for inductive loads, Instantaneous switching In this version the solid-state contactor is specifically matched to inductive loads. Whether it is a matter of frequent actuation of the F1 K1 1 2 I,A L T valves in a filling plant or starting and stopping small drives in packet distribution systems, operation is carried out safely and R1 noiselessly. Special Low noise version Thanks to a special control circuit, this special design can be used in public networks up to 16 A without any additional measures such as interference suppressor filters. As a result it conforms to limit value curve class B according to More information Selecting solid-state contactors EN in terms of emitted interference. Special Short-circuit-resistant version Skilful matching of the power semiconductor with the performance of the solid-state contactor means that short-circuit strength can be achieved with a standard miniature circuitbreaker. In combination with a B-type MCB or a conventional fuse, the result is a short-circuit resistant feeder. In order to achieve problem-free short-circuit protection by means of miniature circuit-breakers, however, certain boundary conditions must be observed. As the magnitude and duration of the short-circuit current are determined not only by the short circuit breaking response of the miniature circuit-breaker but also the properties of the wiring system, such as the internal resistance of the input to the network and damping by controls and cables, particular attention must also be paid to these parameters. The necessary cable lengths are therefore shown for the main factor, the conductor resistance, in the table below. The following miniature circuit-breakers with a type B tripping characteristic and 10 ka or 6 ka breaking capacity protect the 3RF23..-.DA.. solid-state contactors in the event of short-circuits on the load and the specified conductor cross-sections and lengths: Ltg NSB0_0173b F1 K1 3/N/PE 50 Hz 230/00 V L1 L2 L3 N The setup and installation above can also be used for the solid-state relays with a I 2 t value of at least 6600 A 2 s. The solid-state contactors are selected on the basis of details of the power system, the load and the ambient conditions. As the solid-state contactors are already equipped with an optimally matched heat sink, the selection process is considerably simpler than that for solid-state relays. The following procedure is recommended: Determine the rated current of the load and the mains voltage Select a solid-state contactor with the same or higher rated current than the load Check the correct contactor size with the aid of the rated current diagram, taking account of the design conditions 1 L 2 T Ltg F2 I,A R1 Ltg Rated current of the miniature circuitbreaker Example of type 1) 6 A 5SY 106-6, 5SX A 5SY 110-6, 5SX A 5SY 116-6, 5SX A 5SY 116-6, 5SX A 5SY 120-6, 5SX A 5SY 125-6, 5SX Max. conductor cross-section 1 mm 2 5 m 1.5 mm 2 8 m 1.5 mm 2 12 m 2.5 mm 2 20 m 2.5 mm 2 20 m 2.5 mm 2 26 m Cable length from contactor to load 1) The miniature circuit-breakers can be used up to a maximum rated voltage of 80 V. /16 Siemens LV 1 T 2006
