Eaton EHD3080L - 80 A, 480 V, 3-Pole Circuit Breaker | AmpState

The Eaton EHD3080L is an 80 A, 480 V, 3-pole molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Built for three-phase distribution, this breaker helps safeguard downstream equipment and wiring from overcurrent and short-circuit events while fitting seamlessly into Eaton’s panel ecosystems.

• Compact molded case design minimizes footprint and maximizes usable panel space, making it easier to organize and maintain larger electrical distributions.
• Thermal-magnetic trip unit provides stable, repeatable protection by responding to both overloads (thermal) and short circuits (magnetic) without nuisance trips, helping your system stay online when it matters most.
• 3-pole configuration for 480 V services ideal for commercial and light industrial applications that require reliable three-phase protection up to 480 V.
• OEM loadcenter and panelboard compatibility designed to pair with matching Eaton load centers, ensuring plug-and-protect reliability and straightforward replacement in established installations.
• Versatile protection for a range of applications suitable for residential, commercial, and light industrial panelboards where robust branch-circuit overcurrent and short-circuit protection is required.

What sets the EHD3080L apart

Rather than a generic breaker, the EHD3080L is purpose-built to align with Eaton’s panelboard ecosystems, delivering predictable trip behavior and streamlined maintenance. The combination of a compact form factor and a thermal-magnetic trip unit means you gain reliable protection without sacrificing panel real estate, while guaranteed compatibility reduces installation guesswork and future service headaches.

Practical tips for installation and use

• Verify that your panelboard is designed for a 3-pole, 480 V molded case breaker and that the EHD3080L is a compatible match for your Eaton loadcenter.
• When replacing an existing breaker, ensure the replacement is seated firmly and the latches engage securely to maintain proper enclosure integrity.
• Plan for a professional installation when handling high-voltage equipment to ensure correct wiring, labeling, and compliance with local electrical codes.
• Keep a spare on hand for critical panel sections that require quick fault isolation and minimum downtime during maintenance or repair schedules.
