Busbar for the 3VU13 Switch Line
The Siemens 3VU9135-1KA04-0RE0 is a 3-phase busbar accessory designed for the 3VU13 switch family. It distributes three-phase power across four 3VU13 switches in a panel, with a modular spacing of 4MW. This is the busbar piece you spec when you need a common feed to multiple 3VU13 disconnects or motor-protective switches in a row.
Panel Integration
Mounts into the 3VU13 switch base, linking the line-side terminals of four adjacent units. The 4MW modular spacing matches the standard 3VU13 width, so the busbar aligns without extra adapters. Plan for the busbar length when laying out the DIN-rail assembly — it spans four switch positions.
