Product description
Shipping

Meet the Federal Pioneer QMQB1136R — a rugged, 3-pole fusible panelboard switch engineered for lighting and distribution panelboards. Built to withstand busy commercial electrical rooms, it delivers dependable load switching and integrated overcurrent protection when paired with the appropriate fuse class. As a member of the QMQB series, the QMQB1136R is designed for straightforward integration into standard panelboard assemblies, making it a smart choice for upgrades, retrofits, or new installations in lighting and distribution applications.

Key Features

  • Three-pole configuration to control three-phase feeders in a single unit, simplifying wiring and maintenance.
  • 100 A rating with a 600 V maximum rating, ideal for mid-size distribution circuits and lighting feeders.
  • Fusible panelboard switch design that enables integrated overcurrent protection when used with the correct fuse class, reducing parts count and simplifying protection coordination.
  • QMQB series compatibility for reliable integration with standard lighting and distribution panelboards.
  • Durable construction and clear labeling to support safe isolation during service activities in busy commercial environments.

Why choose this fusible panelboard switch

The QMQB1136R offers a compact, all-in-one solution for three-phase feeders that consolidates protection devices without compromising safety or code alignment. By pairing with the appropriate upstream protection, you gain coordinated protection that reduces wiring complexity and maintenance effort. This unit is especially valuable in spaces where reliable switching and straightforward service isolation are priorities—such as data centers, schools, offices, healthcare facilities, retail locations, and light manufacturing environments.

Ideal use cases

  • Panelboard upgrades where a fusible, space-saving solution is preferred for three-phase lighting and distribution circuits.
  • New installations in electrical rooms that require coordinated protection with minimal component count.
  • Retrofits in mid-size facilities aiming to simplify maintenance, labeling, and isolation procedures during service.

Installation & safety considerations

For proper operation, pair the QMQB1136R with the appropriate upstream protection and fuse class as part of a coordinated protection scheme. Confirm panelboard compatibility within the QMQB series and follow applicable local electrical codes during installation. Ensure secure mounting, correct phase alignment, and adequate enclosure clearances to maintain safe operation and serviceability.
