I-Line® Plug-on Unit with Surgelogic™ TVSS
A high performance TVSS unit that plugs easily onto the bus stack of an
I-Line interior in Panelboards, Switchboards, Modular Panelboard Systems and Integrated Power Centers.

• Versatility. I-Line plug-on units with Surgelogic TVSS can be installed in I-Line panelboards, Modular Panelboard Systems (MPS), Integrated Power Centers (IPC) and QED switchboards.
  
• Compact Design. Integrated TVSS unit and FC or FI circuit breaker disconnect requires only 13½" of K-frame branch mounting space on one side of the bus stack. Competitive bus connected TVSS units require from 9" to 13¾" of twin unit mounting space.
  
• 200 kA SCCR Meets Requirements of the 2002 NEC Change.
  I-Line plug-on units with Surgelogic TVSS meet the new 2002 NEC SCCR requirements. The I-Line TVSS unit has been tested up to 200 kA SCCR to comply with 2002 NEC changes.
  
• Retrofit Ready. I-Line plug-on TVSS units are suitable for retrofit in all existing I-Line panelboards and switchboards. This equates to over 30 years of installed base having retrofit potential.
  
• Labor and Money Savings. Easily installs in less than one minute and reduces the amount of cable and conduit required compared to wall mounted TVSS units. Plus all phase connections are pre-wired at the factory.
  
• Application Flexibility. The I-Line plug-on TVSS unit is suitable for service entrance and non-service entrance application. Competitively Priced. The I-Line plug-on TVSS unit has been price positioned at market levels that are competitive with comparable units.
  
• Lower Installed Cost. The total installed cost of an I-Line plug-on TVSS unit is approximately $400 less than a comparable externally mounted TVSS that has been installed and wired by the electrical contractor.
