What it is and what it does
The Siemens 3RV1915-5AA00-0FJ0 is a 3-phase INCOM feeder terminal designed to feed power from the top into 3-phase busbar systems for SIRIUS 3RV size S0 and S00 motor starter protectors and contactors. It uses pin-style connections (Fa. Benedikt & Jaeger) and mounts directly onto the busbar assembly, eliminating the need for separate wiring to each device's line side.
Integration note
Top-entry design keeps the busbar feed clear of the devices below, simplifying panel layout and reducing the bend radius on incoming cables. The pin interface mates directly with the busbar slots on S00 and S0 frames — no adapter or additional hardware required. Verify the busbar system matches the pin pitch before committing the panel layout.
