GE QMR324 - 200A, 240V, 3-Pole, Fusible, Switch

Introducing the GE QMR324 — a robust 200A, 240V, 3-Pole Fusible Switch engineered for dependable on/off isolation and precise overcurrent protection in demanding industrial and commercial settings. Built to endure tough environments, this switch delivers straightforward control for three-phase systems while keeping protection simple and accessible.

Why the GE QMR324 stands out

Designed for reliability in everyday operations, the QMR324 combines a compact, maintainable form with integrated protection. Its fusible construction provides immediate response to overcurrent events, helping to safeguard motors, control circuits, and other critical equipment. The three-pole design ensures all three phases are disconnected together, enhancing safety during maintenance and servicing.

• Three-Pole operation: simultaneous disconnection of all phases for complete isolation and safer servicing.
• 200 A at 240 V: ample capacity to handle sizable motor loads, panelboards, and branch circuits.
• Fusible protection: built-in overcurrent protection with a straightforward maintenance path.
• Compact, maintainable design: fits into standard switchgear and panelboard applications without adding bulk.
• Ideal applications: motor disconnects, panelboards, and branch circuit protection where a dedicated, easy-to-service fusible switch is required.

Who should consider the GE QMR324?

Electrical engineers, project integrators, and facility managers working with three-phase equipment will gain from a dedicated fusible disconnect that simplifies protection strategies. It’s a practical fit for manufacturing lines, HVAC motor circuits, conveyors, pumps, and other sizeable loads that demand reliable isolation and quick protection response.

Use cases in the real world

• Motor disconnects for large fans, pumps, conveyors, and processing equipment.
• Primary or secondary protection in panelboard enclosures where space is at a premium.
• Branch circuit protection for critical machinery, enabling rapid de-energization for maintenance.
• Retrofit projects that require a compact, fusible switch with straightforward serviceability.

What makes it better than generic switches

Unlike non-fusible disconnects, the GE QMR324 combines isolation and overcurrent protection in a single, purpose-built unit, reducing wiring complexity and measurement points. The 3-Pole configuration ensures consistent, three-phase de-energization, which improves safety margins during servicing and minimizes the risk of partial energization.
