Eaton QCGFT2040 - 40 A, 240 V, 2-Pole Circuit Breaker | AmpState

Meet the Eaton QCGFT2040—a 40A, 240V, 2‑pole molded case circuit breaker designed to deliver reliable branch circuit overcurrent and short‑circuit protection in panelboards and load centers. Its compact form helps you maximize panel space without compromising protection, making it a smart choice for modern residential, commercial, and light industrial electrical installs.

Why the QCGFT2040 Stands Out

• Compact molded case design minimizes intrusion into valuable panel space, enabling neater wiring, easier wiring access, and more room for future circuit additions.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining heat sensing for overload with magnetic tripping for high‑fault events. This reduces nuisance trips while delivering fast response to short circuits.
• 2-pole, 40A, 240V configuration delivers synchronized protection on both conductors of a circuit, ensuring a reliable and coordinated shutdown across the entire branch circuit.
• OEM‑compatible designed to work with matching Eaton loadcenters and panelboards, helping you achieve proper fit, reliable trip coordination, and straightforward replacement when needed.
• Versatile for multiple environments ideal for residential panels, commercial electrical rooms, and light industrial setups where dependable protection and space efficiency are valued.
