Eaton KD3250X - 250 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton KD3250X is a 250A, 600V, 3-pole bolt-on molded case circuit breaker designed to provide dependable overcurrent and short-circuit protection for panelboards and load centers. Engineered for residential, commercial, and light industrial environments, it delivers consistent protection where reliability matters most.

Why the KD3250X stands out

• Secure bolt-on mounting ensures a rigid, vibration-resistant bus connection that stays tight in busy electrical racks and where equipment may shift during operation.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to overloads (thermal) and delivering instantaneous short-circuit protection (magnetic) when surge conditions occur.
• 3-pole design supports three-phase systems or multi-wire configurations, making it versatile for commercial and light industrial panels.
• 250A rating at 600V provides robust protection for high-demand branch circuits and feeder applications without compromising selectivity or nuisance tripping.
• OEM-compatible designed to snap into place with matching Eaton OEM load centers and panelboards for a seamless, reliable installation.
