Eaton JDB3225 - 225 A, 600 V, 3-Pole Circuit Breaker | AmpState

Eaton JDB3225 is a 225A, 600V, 3-pole molded case circuit breaker engineered to protect panelboards and loadcenters from overcurrent and short-circuit events. Built for reliable performance in residential, commercial, and light industrial environments, this breaker delivers consistent protection where it matters most.

Why the JDB3225 Stands Out

• Space-conscious molded-case design: a compact profile helps maximize panel space and simplifies wiring in tight enclosures, enabling cleaner, more efficient electrical layouts.
• Thermal-magnetic trip unit: combines thermal overload protection with instantaneous magnetic trip for fast, predictable response to short circuits, reducing the risk of conductor damage and downtime.
• 3-pole configuration: ideal for 3-phase systems and multi-wire branch circuits, providing coordinated protection across all phases in commercial and light industrial applications.
• High-capacity protection: rated at 225A and 600V, it safely interrupts substantial fault currents while preserving system stability and equipment integrity.
• OEM compatibility: designed to be compatible with matching Eaton loadcenters and panelboards, making retrofit and replacement straightforward without compromising panel performance.

Practical Use Cases

• Upgrading panel protection for commercial electrical rooms, ensuring robust safeguarding for feeders and large loads.
• Retrofits in existing Eaton-based installations where a reliable, high-amperage 3-pole breaker is required.
• New installations in light industrial settings that demand consistent trip performance and space-efficient panel layouts.
