Eaton HFD2040L - 40 A, 600 V, 2-Pole Circuit Breaker | AmpState

The Eaton HFD2040L is a purpose-built, 40A, 600V, 2-pole molded case circuit breaker that brings reliable branch circuit protection to panelboards and load centers. Designed to maximize space without sacrificing safety, this compact unit fits neatly into residential, commercial, and light industrial electrical layouts, delivering dependable overcurrent and short-circuit protection where you need it most.

• Compact molded case design: Slim profile to optimize panel space, making it easier to fit multiple breakers in tight enclosures while maintaining clear labeling and organization.
• Thermal-magnetic trip unit: Combines slow-operating thermal protection with fast magnetic protection for precise, repeatable responses to overloads and short circuits, reducing nuisance trips and protecting sensitive circuits.
• Two-pole protection: Simultaneously disconnects both conductors for safer shutdown and enhanced protection of multi-wire branch circuits and connected loads.
• OEM compatibility: Engineered to integrate seamlessly with matching Eaton load centers and panelboards, ensuring dependable electrical coordination and a straightforward replacement or upgrade path.
• Versatile applications: Ideal for residential service upgrades, commercial panelboards, and light industrial feeders where compact protection is essential and reliability is non-negotiable.

Where and how this fits into real-world setups

Use the Eaton HFD2040L to protect branch circuits that require a solid 40A rating up to 600V. In a home or small business panel, it acts as a robust line of defense against overloads and short circuits on circuits with higher current demands, such as workshop tools, HVAC controls, or lighting and receptacle branches. In retrofit scenarios, its OEM compatibility minimizes compatibility concerns and simplifies upgrades without sacrificing safety or performance.

Why it stands out

Compared to generic breakers, the HFD2040L is purpose-built for Eaton panel ecosystems, delivering tighter integration and predictable trip behavior. The thermal-magnetic design provides stable protection across varying loads and temperatures, so you can count on consistent performance throughout the life of the installation. Its 2-pole construction ensures safe, simultaneous disconnection, which is crucial for protecting multi-wire circuits and maintaining overall electrical system safety.
