Eaton QBGFT2040 - 40 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Eaton QBGFT2040 — a dependable 40A, 240V, 2-pole bolt-on molded case circuit breaker designed to safeguard your electrical system where it matters most. Built for durable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters, this breaker delivers consistent performance in a variety of environments.

Why the Eaton QBGFT2040 Stands Out

• Secure bolt-on mounting: Provides a rigid, vibration-resistant bus connection that stays put under movement, vibration, or busy electrical rooms.
• Thermal-magnetic trip unit: Combines thermal overload protection with instantaneous magnetic trip for stable, repeatable protection across temperature changes and fault conditions.
• OEM-compatible design: Engineered to fit seamlessly with matching OEM loadcenters and panelboards, making replacements and upgrades straightforward.
• Versatile for multiple settings: Ideal for residential, commercial, and light industrial applications where reliable circuit protection is essential.

What This Breaker Solves

In residential panels or commercial load centers, sudden overloads or short circuits can threaten equipment and safety. The QBGFT2040's combination of secure mounting and intelligent trip behavior helps prevent nuisance trips while ensuring swift response to faults. Its bolt-on design is particularly advantageous in retrofit projects or new installations where a solid, serviceable connection is critical.

Ideal Use Scenarios

• Protected feeders and branch circuits in panelboards and loadcenters requiring 240V, 40A capacity.
• Retrofits or upgrades in existing Eaton or OEM panels where a compatible, plug-in-ready replacement is needed.
• Residential subpanels, small commercial spaces, and light industrial equipment enclosures needing reliable overcurrent protection.

Practical Tips

• Verify compatibility with your panelboard or loadcenter's mounting and trip curves before replacement.
• Store and handle the breaker carefully to maintain the integrity of the bolt-on connection during installation.
• Schedule routine electrical inspections to ensure the bolt-on connection remains tight and corrosion-free for long-term reliability.
