Federal Pioneer QMQB9036 - High-Amp, 600V, 3-Pole Panelboard Switch / Switchboard Unit | AmpState

The Federal Pioneer QMQB9036 is a high-amp, 3-pole fusible panelboard switch purpose-built for lighting and distribution panelboards. Designed to deliver dependable load switching paired with reliable overcurrent protection, it integrates critical safety functionality directly into your panel when used with the appropriate upstream protection and fuse class.

• Three-pole design supports three-phase systems, aligning with standard industrial and commercial panel layouts.
• 600-volt rating for safe operation in medium-voltage panelboards common in commercial facilities.
• Fusible panelboard switch combines switching and overcurrent protection in a single unit, simplifying wiring and protection strategy.
• High-amp capability designed for demanding applications; typical installations consider up to 1200A with the right upstream protection and fuse class (verify the exact amperage for your installation).
• Proven lineage from Federal Pioneer / Federal Pacific, offering a legacy of reliable performance in critical power-distribution setups.
• QMQB series integration designed for compatibility with QMQB panelboard configurations (part number QMQB9036).
• Ideal for lighting and distribution panelboards in commercial buildings, warehouses, and manufacturing facilities, as well as panelboard upgrades or retrofits seeking integrated switching and protection.

How it works and why it matters

In operation, the QMQB9036 acts as a fusible switch within a panelboard, providing controlled load interruption while delivering overcurrent protection when paired with correctly rated upstream protection and fuse class. This integrated approach helps safeguard downstream equipment from short circuits and overloads, while simplifying the protection strategy inside panel assemblies.

Installation considerations

• Ensure compatibility with your upstream protection and fuse class.
• Verify the exact amperage rating according to your installation requirements.
• Match the fuse type and class to your panel’s design to maintain proper protection coordination.
• Intended for use within panelboard assemblies, offering a consolidated solution for switching and protection in a single, reliable unit.
