Eaton’s customised VisoVac is a three-phase medium-voltage fault interrupter. It utilises Eaton’s proven vacuum interruption technology and is available with visible isolation and visible grounding capability. The switchgear can be customised to meet the needs of almost any switching application including custom controls and unique dimensional requirements.
