Siemens 6RY1803-0CA05 Field Supply
An active Siemens field-supply spare part identified with assembly reference C98043-A7116-L1.
Overview
6RY1803-0CA05 is identified by Siemens as a spare-part field supply with assembly reference C98043-A7116-L1.
The official product record lists the item as active and supplied as one piece. The full 6RY order number and the C98043 assembly identity should both be retained during replacement.
Because it is a host-dependent drive-system spare, the installed converter, assembly revision, connector layout and field-circuit documentation remain part of the compatibility check.
