Rectifier Disconnect Switch

Rectifiers that serve cathodically protected structures, such as pipelines, can be subject to various field effects that pose a hazard to maintenance staff. Pipelines near high voltage power transmission structures may have magnetically induced alternating current and voltage affect the pipeline, which can translate back to the rectifier, causing risks for personnel. Pipeline measurements during surveys can also be influenced due to AC induction applied to the rectifier. The Dairyland Rectifier Disconnect Switch is a compact and safe make-break switch to separate rectifier DC output from field connections to address these problems.



  • Rated for most rectifier installations
  • UL, C-UL listed switch design
  • Contacts enclosed during switching
  • No arc exposure
