Product description
Shipping

The Federal Pioneer QMQB1136C is a rugged fusible panelboard switch built for dependable load switching and precise overcurrent protection within lighting and distribution panelboards. As part of the QMQB series, this 3-pole unit delivers a definitive disconnect point, designed to pair with upstream protection and the correct fuse class for tailored protection coordination.

Why the QMQB1136C stands out

  • Three-pole isolation: Seamlessly disconnects all three hot conductors at once, enhancing safety during maintenance and outages.
  • Robust rating: 100 A in a 600 V system—a versatile fit for a wide range of commercial lighting and distribution panelboard applications.
  • Integrated protection approach: Combines with upstream protective devices and fuse classes to create a cohesive, site-specific protection scheme.
  • Retrofit-friendly: An economical, reliable solution for upgrading older panelboards that require explicit disconnect plus overcurrent protection without adding extra devices.
  • Proven compatibility: Built to align with other QMQB components for consistent form, function, and replacement paths.

Ideal use scenarios

  • Installing or upgrading lighting and distribution panelboards in commercial facilities that demand a dedicated serviceable disconnect.
  • Retrofits needing dependable fusible switching to achieve protection coordination with upstream fuses.
  • New builds or controlled environments where a three-phase, all-conductor disconnect enables orderly shutdowns and safer maintenance.

How it fits into your protection strategy

The QMQB1136C is not a stand-alone protector; it works in concert with upstream protection and the correct fuse class. When integrated correctly, you gain:

  • Clear, defined isolation points for service and maintenance.
  • Structured overcurrent protection that coordinates with upstream devices to minimize disruption during faults.
  • A code-friendly, reliable switching solution that consolidates control and protection in a single enclosure.
