GE QMR322 - 60 A, 240 V, 3-Pole Non-Fusible Panelboard Switch | AmpState

When you need a dependable service disconnect inside GE panelboards, the GE QMR322 delivers a precise, ready-made solution built for 3‑phase distribution. This 60 A, 240 V, 3-pole non-fusible panelboard switch provides a clear, reliable isolation point without adding fusing, allowing you to pair it with the overcurrent protection devices your GE system requires.

Exact fit for GE panelboards

Engineered to align with GE mounting patterns and bus connections, the QMR322 installs securely with minimal modification. Its non-fusible design means you get straightforward on/off control while leaving protection to upstream devices, keeping your system clean and predictable.

Key specifications at a glance

• Current rating: 60 A
• Voltage: 240 V
• Poles: 3-pole (switches all three phases simultaneously)
• Configuration: non-fusible panelboard switch
• Compatibility: designed for GE panelboards

Why a non-fusible disconnect matters

In commercial and industrial GE installations, this dedicated disconnect provides a robust isolation point for service, maintenance, and panel upgrades, while overcurrent protection remains in upstream devices. This separation simplifies diagnostics, reduces wiring complexity, and minimizes cross-functional wear between switching and protection components.

Practical use cases

• Maintenance windows: quickly isolate all three phases for safe servicing without disturbing upstream protections.
• Panel upgrades: a reliable, drop-in switch that maintains GE’s mounting and wiring standards during modernization.
• Clear emergency/disconnect signaling: a visible off state that clearly communicates when circuits are isolated.

Who benefits

• Electrical contractors installing or upgrading GE panelboards
• Facility engineers managing commercial or industrial electrical distributions
• Maintenance teams needing a sturdy, non-fusible disconnect with GE compatibility

Important: This is a non-fusible disconnect and does not provide overcurrent protection. Ensure your GE panelboard system includes appropriate protective devices and complies with local electrical codes.
