Economical Solutions for Fault Isolation & Improved System Reliability
Southern States Distribution Automation Solutions are economical vacuum switching devices that can offer greater reliability and improved cost efficiency to a distribution system. Its flexible design allows utilities to employ the automated switch as a sectionalizer, ganged recloser, or triple single recloser available with SEL 751, 351R, 651RA, 651R, Beckwith M7679, or Siemens programmable automation controllers. This all-in-one product can help utilities reduce total inventory, minimize training requirements, as well as provide applicational flexibility to their systems.
Vacuum interrupters housed in hydrophobic cycloaliphatic epoxy (HCEP) offer superior performance and reliability in harsh outdoor conditions. Standard features include 304 stainless steel construction, a 360° field of view position indicator, as well as an amber LED fault indicator light on the bottom of the position indicator
NOTE: The recloser product line is only available for the US and Canadian markets at this time.
