Eaton EHD2040L - 40 A, 480 V, 2-Pole Circuit Breaker | AmpState

Eaton EHD2040L is a 40A, 480V, 2-pole molded case circuit breaker designed to deliver reliable overcurrent and short-circuit protection for panelboards and loadcenters. Built to integrate smoothly with Eaton OEM systems, this breaker helps you maintain safe, code-compliant electrical distribution in a range of settings.

• Compact molded-case design minimizes footprint and frees up valuable panel space, making it easier to organize dense electrical panels without sacrificing protection.
• Thermal-magnetic trip unit provides stable, repeatable protection by quickly reacting to short-circuit events while Preventing nuisance trips from harmless inrush.
• 2-pole, 40A, 480V configuration suits medium-load circuits and higher voltage distribution in commercial and light industrial environments.
• OEM-compatible ensures seamless replacement in matching Eaton loadcenters and panelboards, reducing downtime and configuration issues.
• Versatile application suitable for residential, commercial, and light industrial projects where dependable protection is critical.

In real-world use, the EHD2040L protects electrical circuits from overloads and short circuits, preserving equipment, reducing fire risk, and aiding safe maintenance. You can rely on it for feeding critical lighting circuits in a small business, safeguarding power rails for machinery in a light-industrial space, or upgrading an aging panel to support new electrical loads.

Why this breaker stands out

Compared with generic options, the EHD2040L combines Eaton engineering with a compact molded case and a proven thermal-magnetic trip curve calibrated for predictable performance across voltage and temperature swings. The result is a breaker that fits your panel better and delivers consistent trip timing when faults occur, reducing downtime and maintenance headaches.
