QED 2 Switchboards: Versatility & Performance

Group-mounted switchboards with molded case circuit breakers

Standard or custom QED 2 switchboards feature Schneider Electric's unique I-Line® plug-on connections in group-mounted construction.


A screwdriver is the only tool required to firmly ratchet the line end of a molded-case circuit breaker directly onto the I-Line bus assembly. This plug-on design allows for quick installation and mounting flexibility of circuit breakers up to 1200A.

For circuit breakers over 1200A, QED 2 (and QED 6) allows fixed-mount and drawout power circuit breaker options.

Key features include:

  • Small footprint
  • Front accessibility
  • Energy reduction maintenance setting (ERMS)
  • Quick connect bus design
  • State-of-the-art circuit protection
  • I-Line plug-on connections

Innovation That Sets the Standard

QED 2 switchboards set the standard for reliability through continuous innovation, and meet a wide range of requirements and specifications. This includes integrating power metering and communications capabilities that provide direct access to energy management at main and feeder level.
