Eaton EDH3125L - 125 A, 240 V, 3-Pole Circuit Breaker | AmpState

Eaton EDH3125L is a rugged 125A, 240V, 3-pole molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Designed to meet the needs of residential, commercial, and light industrial installations, this unit combines compact sizing with robust protection to keep critical circuits safe and running smoothly.

• Compact molded case design maximizes panel space, allowing cleaner wiring and easier service access without sacrificing protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding precisely to both overloads and short circuits, reducing nuisance trips and safeguarding connected equipment.
• 3-pole configuration supports three-phase systems common in commercial and light industrial environments, ensuring coordinated protection across all conductors.
• 125A, 240V rating provides a robust, mid-size protection level suitable for a wide range of branch circuits and equipment loads.
• OEM loadcenter compatibility ensures easy integration with matching Eaton panelboards and loadcenters, preserving labeling, fit, and warranty integrity.

Ideal use cases

• Feeder protection for three-phase equipment such as motors, HVAC units, and large lighting installations in commercial settings.
• Replacement in existing Eaton-based electrical systems where a compact, reliable 3-pole breaker is required.

Why this matters

The EDH3125L’s thermal-magnetic trip technology delivers fast fault clearing while maintaining steady performance under varying temperatures and loads. This means fewer trips during normal operation and quicker isolation of faults when they occur—protecting people, property, and critical equipment without constant maintenance or guesswork.
