The Siemens 3RK1903-0AJ00 is a 30 mm power bus jumper for the PE/N (protective earth / neutral) rail in an ET 200S distributed I/O system. It bridges the power bus across ET 200S modules, carrying the protective earth and neutral conductors through the station. This is a panel-level part — it snaps onto the mounting rail alongside the ET 200S interface module and I/O slices, maintaining the PE/N bus without separate wiring per position.
