        Features:

        • Maps the Siemens order number to internal assembly C98043-A7017-L1.
        • Appears in both 1Q and 4Q high-current 6RA70 power connections.
        • Uses X90 at the documented thyristor-branch capacitor positions.
        6RY1703-0FA12 belongs to the power section of the SIMOREG DC-MASTER 6RA70 architecture rather than its control-electronics interfaces.

        The 1Q arrangement places six C98043-A7017 capacitor assemblies around one controlled rectifier bridge.

        A 4Q converter extends the assembly assignment to both bridge directions, making the installed topology part of the identification check.

        The Siemens 6RY1703-0FA12 TSE Capacitor Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Siemens 6RY1703-0FA12 TSE Capacitor Module Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • In a one-quadrant converter, six C98043-A7017 assemblies surround one controlled rectifier bridge instead of being divided between two bridge directions.
        • Each assembly meets its thyristor branch at X90, so the physical branch position is part of the 6RY1703-0FA12 identification check.
        • The three incoming phase paths pass through the V11–V16 bridge before reaching the DC terminals, placing the capacitor assemblies inside the main power circuit.
        • This single-bridge arrangement separates the 1Q installation from the paired forward-and-reverse structure used by a 4Q converter.
        • The four-quadrant arrangement uses two coordinated six-pulse groups, with V11–V16 forming one bridge and V21–V26 forming the opposite-direction bridge.
        • C98043-A7017 capacitor assemblies repeat across both groups because each controlled direction has its own set of thyristor branches.
        • A correct 6RY1703-0FA12 match therefore depends on whether X90 belongs to the V1x group or the V2x group, not on the spare-part number alone.
        • Reading both bridge groups together prevents a module position from the forward path from being confused with the corresponding reverse-path position.
        • X90 is the recurring connection reference on the capacitor assemblies and ties each 6RY1703-0FA12 position to a specific thyristor branch.
        • The 1U1, 1V1 and 1W1 designations identify the three-phase side of the bridge, while 1C1 and 1D1 identify its DC side.
        • Following the node designations from the AC side to the DC side shows where the capacitor module sits within the complete converter path.
        • Using the branch and node references together provides a more reliable location check than comparing only the printed assembly code.
        • The documented 400 V, 575 V, 690 V and 950 V converter classes use different current ratings, so each diagram applies to a defined power configuration.
        • Voltage class does not by itself determine whether the converter is 1Q or 4Q; the bridge arrangement must be checked separately.
        • The high-current connection pages associate 6RY1703-0FA12 with complete converter circuits rather than treating it as a universal capacitor module.
        • Matching the converter nameplate, bridge topology and X90 branch position keeps the spare-part selection inside the documented boundary.
        Description
        Siemens 6RY1703-0FA12 is the TSE capacitor module supplied under internal assembly reference C98043-A7017-L1 for the SIMOREG DC-MASTER 6RA70 platform. It is located in the high-current converter power-connection circuitry rather than the open-loop control section.

        Within the documented 1Q topology, 6RY1703-0FA12 corresponds to C98043-A7017 assemblies connected at X90 around the V11, V13, V15, V14, V16 and V12 thyristor branches. This arrangement places the capacitor modules directly within the six-pulse power path.

        The 4Q connection expands the same 6RY1703-0FA12 assembly reference across the forward and reverse bridge branches. The associated high-current converter classes are 400V/3000A, 575V/2800A, 690V/2600A and 950V/2200A, so the exact 1Q or 4Q circuit and branch position must remain aligned with the installed converter.

        Technical notes

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        How should 6RY1703-0FA12 be matched to the internal Siemens assembly number?
        Use both identifiers: Siemens 6RY1703-0FA12 corresponds to C98043-A7017-L1, while the circuit drawings show the C98043-A7017 assembly family.
        Does Siemens 6RY1703-0FA12 belong to a 1Q or a 4Q converter?
        Siemens 6RY1703-0FA12 appears in documented high-current 1Q and 4Q connections, so the installed bridge topology must be checked before matching the part.
        Which connector reference helps locate 6RY1703-0FA12 in the power section?
        The capacitor assemblies associated with Siemens 6RY1703-0FA12 are marked with connector reference X90 beside the thyristor branches.
        What converter ratings are directly associated with Siemens 6RY1703-0FA12 diagrams?
        The Siemens 6RY1703-0FA12 reference pages cover 400V/3000A, 575V/2800A, 690V/2600A and 950V/2200A high-current converters.
        Before replacing 6RY1703-0FA12, what identification points should be compared?
        Compare the complete Siemens 6RY1703-0FA12 order number, C98043-A7017-L1 marking, 1Q or 4Q topology, and the exact X90 branch position.
        Which manual should be checked when reviewing the SIMOREG DC-MASTER circuit context around 6RY1703-0FA12?
        Use the Siemens SIMOREG DC-MASTER 6RA70 Series Operating Instructions linked in the Manuals tab. It is a series-level reference, so the installed converter order number and circuit configuration must be matched separately.
