Eaton EDB3225 - 225 A, 1 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton EDB3225 is a high-capacity, three-pole bolt-on molded case circuit breaker designed to deliver reliable branch-circuit overcurrent and short-circuit protection in panelboards and loadcenters. With a thermal-magnetic trip unit and a robust bolt-on mounting, this 225A breaker provides precise, repeatable protection in demanding electrical environments.

• Secure bolt-on mounting promotes a rigid, vibration-resistant bus connection, reducing movement and loosening risks in installations subject to vibration or dynamic loads.
• Thermal-magnetic trip unit offers stable, predictable protection that responds quickly to overloads and short circuits, helping protect wiring and connected equipment from damage.
• 3-pole configuration suitable for three-phase systems, making it ideal for feeders and branch circuits in commercial and light industrial applications.
• OEM-compatible design works with matching Eaton OEM loadcenters and panelboards, simplifying replacement, stocking, and service workflows.
• Ampere and voltage specifics rated for 225A with a voltage rating of 1V, ensuring compatibility with systems designed for this specification while maintaining robust protection for critical circuits.
• Versatile application suitable for residential, commercial, and light industrial environments requiring dependable overcurrent and short-circuit protection.

Why this matters for your panels

The EDB3225’s combination of a durable bolt-on mount and a precise thermal-magnetic trip mechanism translates to fewer nuisance trips and more consistent protection across fluctuating loads. Its three-pole design aligns with common 3-phase distribution needs, while OEM compatibility minimizes disruption when upgrading or replacing aging breakers in existing panelboards and loadcenters.

Ideal use cases

• Upgrading panelboards in small commercial spaces or light industrial facilities where 3-phase distribution is standard.
• Replacing aging or failed breakers in OEM Eaton loadcenters to restore reliable protection without extensive panel modifications.
• Feeder circuits demanding solid, vibration-resistant connections in environments subject to mechanical movement or equipment vibration.
• New installations that require a high-current, bolt-on solution for heavy-load branch circuits, ensuring fast disconnection in fault conditions.

Installation and maintenance tips

• Ensure the breaker is compatible with the specific OEM panelboard or loadcenter to maintain warranty and performance guarantees.
• Secure the bolt-on mounting firmly to achieve the intended bus connection rigidity and minimize electrical resistance at the connection.
• Follow manufacturer installation procedures for wiring and torque requirements to maintain the integrity of the thermal-magnetic trip unit.
• Periodically inspect for signs of wear, corrosion, or loosened connections, and replace the unit if any degradation is observed to preserve overcurrent protection.

For professionals upgrading or maintaining Eaton-based electrical systems, the EDB3225 delivers dependable, consistent protection with OEM compatibility, making it a practical choice for high-current, three-phase applications in residential, commercial, and light industrial settings.
