    Reduce the risk of contact with energized electrical parts when servicing panelboards

    Factory-installed IP2X per IEC 60529 Barriers for NQ Panelboards reduce the risk of electrical shock due to inadvertent contact with energized electrical parts. IP2X barriers are designed to prevent people from accessing hazardous parts with a finger.

Innovative Safety from the Leader in Electrical Distribution

Trusted Square D brand NQ Panelboards are now available with two styles of IP2X factory installed plastic barriers that cover energized parts on 400A maximum main lugs or breaker connections, copper bus, and branch breakers (up to 100A). Standard and Enhanced NQ Fingersafe designs allow you to add proven QO or QOB branch circuit breakers with special yellow plastic covers, that together provide IP2X safety at a fraction of the cost of other fingersafe panelboards.

  • UL Listed and CSA rated up to 400A for 3 phase systems up to 240 Vac
  • IP2X per IEC 60529 on all ungrounded parts
  • Fully rated to 65 kA SCCR (with QH(B) branch breakers)
  • Series rated to 125 kA with integral PowerPact H, J, or Q main breaker
  • Selectively coordinated up to 30 k AIC
  • Branch circuits up to 100 Amperes - 1, 2, and 3-pole
  • Installs in most environments – NEMA 1, 2, 3R, 4/4X, 5, or 12 (up to 225A)
    • NEMA 1 panelboards up to 400A
  • Available seismically qualified
  • IP2X per IEC 60529 Fingersafe NQ Panelboards

    Standard NQ and Enhanced NQ Fingersafe designs provide IP2X per IEC 60529 protection against access to hazardous electrical parts with a finger.

    New Enhanced NQ Fingersafe design:

    • • Available up to 225A with main lugs, or PowerPact Q, H, or J frame main breakers
    • • Fully rated to 22kA SCCR (with QOB-VH branch breakers)
