Eaton JD3250KW 250A 600V 3-Pole Circuit Breaker

The Eaton JD3250KW is a robust 3-pole bolt-on molded case circuit breaker designed to deliver reliable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built for continuous performance in demanding environments, this unit combines solid construction with precise protection characteristics that electricians trust.

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection that helps maintain consistent electrical contact and reduces the risk of loose connections in vibration-prone installations.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to both overloads and short circuits, minimizing nuisance trips while safeguarding downstream circuits.
• 3-pole design ideal for three-phase systems, providing coordinated protection across all phases in commercial or light industrial applications.
• 600V rated insulation suitable for a wide range of panelboards, loadcenters, and industrial panels, ensuring compatibility with higher voltage distributions.
• OEM-compatible engineered to work with matching OEM loadcenters and panelboards, simplifying replacement and upgrade projects without wiring changes.

Where this breaker shines

• applications requiring dependable overcurrent protection in panelboards and load centers.
• Panel upgrades and replacements where a trusted, long-lasting bolt-on solution is preferred over alternative mounting styles.
• New installations that demand a high-capacity 250A breaker capable of handling substantial load demands across three phases.

Why choose the Eaton JD3250KW over other options? It combines a rugged bolt-on interface with a thermal-magnetic trip mechanism that maintains protection performance across varying temperatures and loads. The result is fewer nuisance trips, predictable tripping behavior, and a smoother path to code-compliant branch circuit protection in modern electrical distributions.
