The Siemens 3VU9135-1AB03 is an accessory designed for 3VS13 3-phase bus bars used in 4MSP configurations. It is a DIN-rail mounted component that integrates into the panel bus bar system for distributing three-phase power to downstream devices like motor starters and feeders.
This part carries an NRND (Not Recommended for New Designs) lifecycle status, meaning Siemens no longer recommends it for new projects. RoHS compliant since 01-03-17, with REACH candidate list information available on request.
Integration Note
Packaged as a single piece (154 x 32 x 10 mm), this accessory snaps onto the 3VS13 bus bar assembly. No special tooling required for installation — standard panel-builder practice for bus bar accessories.
