Industrial Controls Catalog 6/1 Compact – Hybrid Starters SIRIUS 3RM1 Motor Starters For Use in the Control Cabinet SIRIUS SIRIUS 3RM1 Motor Starters Overview General data Overview Functional density/space savings The 3RM1 motor starters combine the functions direct/reversing starting and overload protection and safety-related shutdown in a single device, without changing the 22.5mm width. For simple applications (such as starting and reversing threephase loads with overload protection), motor starter combinations of power contactors and a solid-state overload relay, for example, can be replaced by a single 3RM1 starter. The more functions are required, the more devices can be replaced. The footprint area required for each motor starter in the control cabinet is reduced by values of 64 to 82%. In the case of assemblies and grouped starter units there are further advantages. Wiring overhead 3RM12 motor starter with reversing functionality and electronic overload protection SIRIUS 3RM1 motor starters are compact devices with a width of 22.5 mm, combining a large number of functions in a single enclosure. They consist of combinations of relay contacts, power semiconductors (hybrid technology), and a solid-state overload relay for operational switching of three-phase motors up to 3 HP (at 480 V). Feature Value Rated current (wide setting range of the electronic overload release) 0.1 ... 0.5 A 0.4 ... 2.0 A 1.6 ... 7.0 A (UL=6.1A) Rated operational voltage 48 ... 500 V Rated frequency 50/60 Hz Rated control supply voltage 24 V DC, 110 V DC, 110 ... 230 V AC Characteristic 3RM10 3RM11 3RM12 3RM13 Direct-on-line starters -- -- Reversing starters -- -- Overload protection with wide setting range ATEX certification overload protection -- -- Safety-related shutdown up to SIL 3 / PLe -- -- By combining various functions in a single device, wiring overhead is reduced. The greater the number of starters, the greater the saving in wiring. Savings can be made in: • mains wiring and space reduction with the use of the 3RM19 three phase infeed system • wiring of the reversing contactor assembly thanks to the integrated design • reduction of control cables for the coils in group applications with the 3ZY12 device connectors 8 These savings reduce the time required for the wiring itself, while at the same time reducing both the risk of wiring errors and the amount of testing required after control cabinets have been completed. Configuration and inventory The wide setting range of the electronic overload release (up to 1:5) reduces the cost of inventory and the considerations involved in configuration where the actual motor current to be expected is concerned. Compared with protection equipment with Trip class CLASS 10A thermal overload protection, only 3 versions are now required to The 3RM1 motor starters with overload protection with wide setcover a current range of 0.1 to 7 A with 3RM1, instead of 17 verting range are offered as 3RM10 direct-on-line starters and 3RM12 sions. reversing starters and as versions with safety-related shutdown. Connection methods Hybrid technology The 3RM1 motor starters combine the benefits of semiconductor technology and relay technology. This combination is also known as hybrid technology. The hybrid technology in the motor starter is characterized by the following features: • The inrush current is is conducted briefly via the semiconductors. Advantage: protection of relay contacts, long service life due to low wear • The continuous current is conducted via relay contacts. Advantage: lower heat losses compared with the semiconductor. • Shutdown is implemented again via the semiconductor. Advantage: the contacts are only slightly exposed to arcs, and this results in a longer service life. The 3RM1 is available with screw terminal, push-in terminals or a combination of both.. Push-in terminals are a form of spring-type connection allowing fast wiring without tools for rigid conductors or conductors equipped with end sleeves. Fine-stranded or stranded conductors with no end finishing are wired using a screwdriver (with a 3.0 x 0.5 mm blade). As with other spring-type terminals, a screwdriver is also required to release the conductor. The same tool as above can be used for this purpose. The advantages of the push-in terminals are found, as with all spring-type terminals, in speed of assembly and disassembly and vibration-proof connection. There is no need for the checking and tightening required with screw terminals. Screw terminals Spring-type terminals The terminals are indicated in the corresponding tables by the symbols shown on blue backgrounds. 6/2 Siemens IC 10 N · 12/2012 Siemens Industry, Inc. Industrial Controls Catalog 8/13 Compact – Hybrid Starters SIRIUS 3RM1 Motor Starters SIRIUS General Data Safety-related shutdown/safety integration Feedback to the control system Thanks to the redundant design of the main circuit and internal monitoring, safety-related shutdown in accordance with SIL 3 / PLe is possible by shutting down the control supply voltage with 3RM11 Failsafe and 3RM13 Failsafe motor starters. Additional safety relays are not required in the main circuit. The electronic output in the 24 V DC control voltage version of the 3RM10 and 3RM12 motor starters allows the status of the connected motor to be reported to the higher-level control system. If the motor starter is controlled via inputs IN1 to 2, once the motor has been switched on and has started up correctly the output "OUT" is set. 3RM1 motor starter Infeed system for the main circuit The 3RM19 infeed system available as an accessory for the main circuit with three-phase busbars allows fast, virtually errorfree wiring of motor starters on the mains connection side and may reduce the number of short-circuit protective devices. IC01_00178 3SK1 safety relay Motor Combination of four SIRIUS 3RM1 Failsafe motor starters with SIRIUS 3SK1 safety relay to allow safety-related collective disconnection of connected motors 3RM1 motor starters are ideal for combining with the 3SK1 safety relay (see Chapter 13 "Safety Technology" "SIRIUS 3SK1 Safety Relays"). They can be combined by means of: • conventional wiring • a special device connector 8 This makes it very simple to shut down connected motors collectively. The wiring, and ultimately the shutting down of the control supply voltage in Emergency Stop situations, is performed via the device connector. There is no further need for complex looping of the connecting cables.

Industrial Controls Catalog Compact - Hybrid Starters SIRIUS 3RM1 Motor Starters SIRIUS Accessories Overview Accessories for 3RM1 motor starters The following accessories are available for the 3RM1 motor starter: • 3-phase infeed system for the main circuit • Device connectors for the control circuit • Spare terminals for main and control circuits - With screw terminals - With push-in spring-type terminals • Push-in lugs for wall mounting the motor starters • Sealable cover as protection against unauthorized access Three-phase infeed system (3RM19 three-phase busbar system) These busbars are available in three lengths, thus allowing 2, 3 or 5 motor starters (arranged side-by-side) to be connected at the same time. More than 5 devices can be connected by clamping the connection tags of an additional busbar rotated by 180° (e.g. 6 devices using one 5-pole busbar and one 2-pole busbar). A single motor starter can be removed from the assembly without loosening the terminal screws of neighboring motor starters. The maximum summation current must not exceed 25 A. Primary infeed is connected via a three-phase infeed terminal. The three-phase busbars are finger-safe but empty connection tags must be fitted with covers. Special three-phase busbar systems can be used to provide an easy, time-saving and safe means of feeding two or more 3RM1 motor starters with screw terminals.

Contact with the unused connection tags in unoccupied positions is prevented safely by the covers. Siemens Industry, Inc. Industrial Controls Catalog 6/5 Compact - Hybrid Starters SIRIUS 3RM1 Motor Starters SIRIUS Accessories Device connectors for the control circuit The outlay for cabling between the devices is reduced using device connectors snapped onto a mounting rail, or screwed onto a level mounting panel (one device connector per motor starter). By using device connectors, several motor starters can be jointly supplied with a control supply voltage of 24 V DC. This requires the control supply voltage to be applied to the A1 and A2 terminals of only one motor starter. Up to ten motor starters can be connected with device connectors. The 24 V DC control supply voltage must be within the operating range of 0.9 to 1.1 for this purpose. If the full operating range of 0.8 to 1.25 is to be used, no more than five motor starters can be used. IC01_00218 Using the device connectors only for feeding in the control supply voltage If the motor starters are not to be interconnected side-by-side, device daisy chain connectors must be used for the gaps. When removing a motor starter, the corresponding device connector must be replaced by a device daisy chain connector if the control voltage is not to be interrupted for motor starters on the right. The last motor starter in a row can be placed on a device termination connector. Flush termination of the configuration is thus possible. Device connectors snapped onto a standard mounting rail to allow the joint connection of the control supply voltage for 3RM1 motor starters or connection to the 3SK1 safety relays Using device connectors in conjunction with 3SK1 safety relays Usage restrictions for accessories • The 3RM19 3-phase infeed system for the main circuit can only be used with 3RM1 motor starters with screw terminals. • The device connectors are only suitable for 3RM1 motor starters with a control supply voltage of 24 V DC. Interconnection of several Standard or Failsafe version motor starters into a group can also be used for joint disconnection by a 3SK1 safety relay. To provide for the simultaneous and safe shutdown of several motor starters via a SIRIUS 3SK1 Safety Relay, you can simply interconnect the devices without additional wiring using a device connector. The motors can then also be shut down safely according to SIL 3 / PLe with the motor starters. Up to five motor starters can be operated on one safety relay with device connectors. If the motor starters are not to be interconnected side-by-side, device loop through connectors must be used for the gaps. The last motor starter in a row must be placed on a device termination connector. This closes the circuits that were built up with the connectors.
