Siemens 3RV1935-5A Connector

Siemens 3RV1935-5A is a 3‑phase line‑side terminal (Einspeiseklemme) designed for top‑entry connection to a 3‑phase busbar in Siemens control gear. Classified as an S2 size unit, it serves as a dedicated feeder lug at the line side of drives and motor starters, enabling a compact interface between the main distribution rail and downstream devices. The part is specified for operation up to 108 A and 690 V, making it suitable for industrial cabinet feeders that supply three‑phase devices such as contactors, protective relays, and other DIN rail or panel-mounted components. It accepts a top‑mounted busbar connection, simplifying wiring inside enclosures and reducing wiring complexity at the busbar interface. The 3RV1935‑5A model is offered by Siemens and through authorized distributors, and is used in Siemens Dig.Industr. installations as a fixed, non‑switching connector block designed to remain in place within the busbar assembly.
