GE QMR363 - 100 A, 600 V, 3-Pole Non-Fusible Panelboard Switch | AmpState

Meet the GE QMR363—a 100 A, 600 V, 3-pole non-fusible panelboard switch engineered to integrate seamlessly with GE panelboards. This robust isolation switch delivers a clear, physical disconnect for maintenance, testing, and commissioning in demanding commercial and industrial electrical systems.

Why this three-pole, non-fusible switch matters

• Complete three-phase isolation: The 3-pole design switches all three phases, ensuring a full disconnection of a three-phase circuit for safe servicing and commissioning.
• Non-fusible clarity: As a pure switching device without built-in fuses, it pairs with your existing protection strategy, preserving system flexibility and upgrade paths.
• GE panelboard compatibility: Precisely engineered to fit GE panelboards, providing secure mounting and reliable electrical connections without adapter kits or modification.
• Durable, industrial-ready build: Designed for longevity in busy facilities, with straightforward wiring that supports long-term service in commercial and industrial environments.

Key specifications at a glance

• Rating: 100 A, 600 V
• Configuration: 3-pole, non-fusible
• Application: Isolation switch for GE panelboards, ideal during maintenance, modernization projects, or new installations requiring a clean, non-fusible disconnect
• Purpose: Physical disconnect point that doesn't include fuse elements, leaving protection devices to be selected or adjusted as needed

Ideal use cases

• Service disconnects during routine maintenance in GE-based distributions
• Panelboard modernization projects where a defined, non-fusible isolation point is required

Practical benefits and how it solves real-world problems

The GE QMR363 provides an immediate, definite disconnect without fuse elements, simplifying maintenance workflows, reducing downtime, and minimizing the risk of accidental energization. Because it is non-fusible, you retain flexibility to upgrade protection devices later, without being tethered to a built-in fuse design. This makes it particularly valuable for facilities that retrofit or expand GE panelboards, perform regular commissioning, or implement phased electrical modernization plans.

Installation and best-practice tips

• Confirm 3-pole, 100 A, 600 V compatibility with your GE panelboard model before installation
• Follow standard mounting and wiring practices per applicable electrical codes and safety guidelines
• Plan your protection scheme separately from the switch, since the QMR363 does not include fuses
• Maintain appropriate PPE and lockout/tagout procedures during installation and servicing
