Distribution Automation Solutions

Economical Solutions for Fault Isolation & Improved System Reliability

Southern States’ Distribution Automation Devices are economical, vacuum switching solutions that offer greater reliability to a distribution system. Their configurable designs can be deployed by utilities as a sectionalizer or a recloser. Controls are available with SEL 751, 351R, 651RA, 651R2, or Beckwith M7679 programmable automation controllers.

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
