Overview
Meet the Eaton EHD1040L, a 40A, 277V, 1-pole molded case circuit breaker engineered to protect branch circuits in panelboards and loadcenters. Its compact design maximizes panel space while delivering dependable overcurrent and short‑circuit protection for modern electrical systems.
Why this breaker stands out
- Space-efficient molded case design frees up valuable panel real estate without compromising protection.
- Thermal-magnetic trip unit delivers stable, repeatable protection: the thermal element handles sustained overloads, while the magnetic action activates instantly on high-current faults.
- OEM-compatible compatibility designed to work with matching Eaton panelboards and loadcenters for seamless integration.
- Versatile across residential, commercial, and light industrial applications that require reliable 277V branch-circuit protection.
Where and how you’ll use it
The 40A, 277V rating makes this breaker ideal for circuits feeding lighting, receptacles, small motors, or equipment in 277V environments. It’s a practical upgrade or replacement option for panel installations in offices, retail spaces, service upgrades, or light industrial setups where compact protection is essential and space in the panel is at a premium.
Practical benefits and outcomes
- Peace of mind from consistent trip performance under both overload and short-circuit conditions.
- Cleaner panel organization thanks to a single-pole design that simplifies wiring and layout.
- Long-term reliability by aligning with Eaton’s protection strategy across compatible panel systems.
Use cases
- Replacing a failed or aged 40A, 277V single-pole breaker in an existing panelboard or loadcenter.
- Upgrading branch-circuit protection for 277V lighting or receptacle circuits in commercial spaces.
- Adding robust protection for 277V-powered equipment in light industrial environments.
