Eaton CHFN240GF - 40A, 2-Pole, GFCI Ground-Fault Circuit Breaker

The Eaton CHFN240GF is a 40A, 2-Pole GFCI Ground-Fault Circuit Breaker engineered for demanding industrial, commercial, and OEM environments. In one rugged device, it delivers precise overcurrent protection plus reliable ground-fault sensing to keep distribution panels and motor control centers operating safely and with reduced risk from leakage currents.

• 40A, 2-Pole configuration protects both hot conductors in a single unit, simplifying panel layouts and wiring while delivering coordinated protection.
• GFCI ground-fault protection monitors for imbalances between live and neutral paths, tripping the circuit to prevent electric shock hazards and minimize equipment damage.
• Versatile installation for panelboards, switchboards, and control panels this breaker is ready to integrate into existing Eaton architectures and new builds alike.
• Industrial-grade reliability built to withstand the rigors of distribution panels and motor control centers in busy facilities, ensuring consistent protection when it matters most.
• Targeted for critical applications ideal for environments where dependable overcurrent and ground-fault protection is essential to safety, compliance, and uptime.

Ideal use cases

Choose the CHFN240GF when you need robust, space-efficient protection in:

• Distribution panels and panelboards in manufacturing plants
• Motor control centers where combined overcurrent and ground-fault protection is desired
• Commercial electrical rooms requiring reliable safety interlock for feeders and branch circuits
• OEM equipment where a compact, two-pole GFCI device integrates into control systems

Why this Eaton GFCI breaker stands out

Rather than separate protection devices, the CHFN240GF combines essential safety features in one compact package, reducing installation complexity and potential fault points. Its 2-pole design ensures balanced protection across both hot legs, while GFCI functionality adds an extra layer of protection against ground faults that could lead to shock or equipment damage. This makes it an attractive choice for facilities that prioritize safety, reliability, and streamlined electrical design.

Practical guidance for installation and care

To maximize performance and longevity, align the CHFN240GF with your existing Eaton system architecture, verify compatibility with your panelboards and switchgear, and follow standard electrical safety practices during installation. Regular inspection and adherence to applicable safety protocols will help ensure consistent protection across your distribution network.
