LV Switchboards - QED-6 Switchboards

Compartmentalized, Rear-Connected Drawout UL891 Switchboards
Critical power operations require worry free, hassle free performance...and we know that. That's why we developed the QED-6 rear-connected switchboard.

QED-6 switchboards with Masterpact NW UL 489 Listed circuit breakers establish Square D with a price-competitive and feature-rich power distribution solution for a variety of applications. Individually mounted, rear connected switchboards are often specified for:

  • Telecommunications Facilities
  • Data Centers
  • Continuous Process Manufacturing Plants
  • Critical Care Facilities

QED-6 Switchboards should be used for critical power applications because:

  • drawout construction is required for quick circuit breaker change-out
  • system requirements call for circuit breakers to close within 5-cycles
  • stored energy circuit breakers are required for reliability
  • front access to control wires is desired for ease of installation, maintenance, and upgrade
  • circuit breaker compartmentalization is required for system integrity
  • segregation of circuit breaker compartments from bus and cable compartments is required for equipment isolation

 QED-6 Rear-Connected Switchboards with Masterpact®  NW and NT Circuit Breakers
The QED-6 Compartmentalized, Rear-Connected Switchboard is ideal for critical power distributions found in hospitals, universities, data processing centers and telecommunications facilities. >more...

Rear connected switchboards offer many of the same benefits as those of our ANSI rated switchgear. Short times withstand ratings on the breakers, structures and as well as high short circuit interrupting ratings. Lower equipment cost, 100% rated drawout breakers (breaker frame sizes to 250A to 5000A) and maintainability for extended life are reasons this product is used in these facilities.

Data Center Application:

  • Main service switchgear
  • Paralleling switchgear
  • UPS input switchgear
  • UPS output switchgear
  • Load bank switchgear

Features and Benefits:
QED-6 switchboard structures offer many of the same benefits as Power-Zone 4 switchgear. Some of these feature differences are:

  • Masterpact and PowerPact® circuit breakers have higher short time ratings and interrupting ratings than competitive products
  • Up to eight Masterpact NT circuit breakers can be mounted in a single 30"-wide section
  • PowerPact circuit breakers 250A and 600A frame for smaller loads
  • Electrically operated breakers UL 489 rated and structure UL 891 listed
  • 150kA SCCR without fuses @ 480V (200kAIR @ 240V)
