Eaton KD3200X - 200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered by Eaton, the KD3200X is a 200A, 600V, 3-pole bolt-on molded case circuit breaker crafted to protect your panelboards and load centers from overcurrent and short-circuit events. Designed for reliable performance in residential, commercial, and light industrial settings, this breaker delivers a sturdy, vibration-resistant connection and precise protection where it matters most.

• Bolt-on mounting for maximum rigidity — a secure, vibration-resistant bus connection that stays locked in even in demanding environments.
• Thermal-magnetic trip unit — combines a dependable thermal element for overload protection with a rapid magnetic trip for short-circuit events, delivering stable, repeatable protection.
• Three-pole design — coordinated tripping across all three phases ensures balanced, safe disconnections in 3-phase systems.
• 200A current rating — suitable for main feeder protection or major branch circuits within panelboards and load centers.
• 600V maximum rating — appropriate for a wide range of commercial and industrial electrical systems.
• OEM-compatible — engineered to pair with matching Eaton OEM load centers and panels for optimal fit, performance, and electrical coordination.
• Versatile application — ideal for residential service upgrades, commercial distribution panels, and light industrial installations where reliable protection matters.

Use cases and practical applications

In a new or existing installation, the KD3200X protects critical feeder and branch circuits from overloads and short circuits, helping to prevent equipment damage and downtime. It’s well-suited for:

• Residential service panels where a robust, long-lasting breaker is needed for main feeders or large circuits.
• Commercial distribution panels that require dependable 3-phase protection with solid bus connections.
• Light industrial subsystems where vibration resistance and stable trip performance are essential in harsh environments.

Why choose the KD3200X over alternatives

This breaker stands out with its bolt-on construction that anchors firmly to the bus, reducing movement and wear in busy installations. The built-in thermal-magnetic trip combines predictable, repeatable protection with fast response to short circuits, helping minimize damage and downtime. Its OEM compatibility means fewer fitment issues and streamlined maintenance when matching Eaton panels or room-ready replacements are needed.
