Simple assembly principle

TracFeed® SFA remote motor drives are installed at the base of the contact line pole and connected to the disconnector via a final controlling element. The switches are usually actuated via a disconnector linkage that establishes a mechanical connection from the remote motor drive to the disconnector at the top of the pole.
