GE QMR312 - 30 A, 240 V, 3-Pole Non-Fusible Panelboard Switch | AmpState

Meet the GE QMR312 — a purpose-built, three-pole, non-fusible panelboard switch designed to deliver reliable isolation for GE panelboards. With a 30 A, 240 V rating, this switch provides clean, deliberate control of three-phase circuits, making it a practical choice for commercial, light-industrial, or equipment-room environments.

Key advantages

• Three-pole reliability — switches all three phases together, ensuring complete circuit isolation and reducing the risk of partial energization during maintenance.
• Non-fusible design — straightforward operation with no internal fuses to manage, simplifying routine servicing and inspections.
• GE panelboard compatibility — engineered to integrate with GE panelboard configurations, supporting smooth retrofit or replacement in compatible enclosures.
• Adequate capacity — rated for 30 A at 240 V, making it suitable for feeders, branch circuits, and control-panel applications that require dependable on/off control.
• Rugged for daily use — built to withstand the demands of busy electrical environments where reliable disconnects are essential.

Ideal use cases

• Primary disconnect for 3-phase 240 V systems in small commercial spaces, manufacturing lines, or HVAC control panels.
• Replacement option for aging panelboard switches where a non-fusible, easy-to-operate solution is preferred.
• Feeder or branch-circuit switch within GE panelboards, providing safe isolation during maintenance or troubleshooting.

What to expect

When installed in the right GE panelboard, the QMR312 offers a predictable, tactile on/off action that isolates all three hot conductors. Its 30 A rating aligns with many common feeders and equipment circuits, while the 240 V capability covers typical 3-phase commercial loads. This combination helps simplify electrical planning, reduce downtime, and support safer maintenance procedures.
