TracFeed® MTS - Rail Power Systems

Mast disconnector

TracFeed® MTS

Perfect modular integration

TracFeed® MTS has proven itself over decades for disconnecting and connecting feeder sections of the contact line. Thanks to its modular design, the mast disconnector can be customised and easily installed at feeder points and insulated overlaps. Not least due to the solid construction and the materials used, Rail Power Systems TracFeed® MTS disconnectors have a very long service life and low maintenance requirements.
