Protect Against Arc Flash with Hoffman Sequestr Disconnects

Hoffman Sequestr is designed to help employers create an Electrically Safe Working Condition (ESWC) for their employees as required by NFPA 70E Standard for Electrical Safety in the Workplace. The Hoffman Sequestr does this by sequestering the line side lugs of the disconnect from the main enclosure. This reduces the risk of accidental contact with the line side power while working in the main enclosure.

 

New Features

  • Mounts on bulletins A21, A28, A34, and AFL3D to easily sequester the disconnect from the large disconnect enclosures
  • Type 4 rating for use either in indoor or outdoor environments
  • Flexible mounting designed for cable operated mechanisms
  • Padlocking handle to restrict access
  • Robust interlock hardware for easy installation and increased safety
  • Larger dimensions and thicker gauge to house higher amperage disconnect switches and circuit breakers
  • Disconnect handle mounts on main enclosure for more robust interlocking
