The Siemens 3VU9135-1BB01 is a 3-phase feed-in terminal designed for busbar systems. It provides a dedicated connection point for feeding three-phase power into a busbar distribution assembly inside a control panel or switchgear enclosure.
Integration Notes
Mounts directly onto the busbar system inside the panel — no additional adapter required. The terminal accepts three-phase conductors and feeds them into the busbar, so verify the busbar cross-section and the conductor lug size match your assembly before ordering.
