• Poles: 4-Pole
• Voltage rating: 600 V
• Part reference: KD4200
• Designed for: maintenance, retrofit, and replacement with matching specs

What sets the KD4200 apart

• 4-pole design provides coordinated disconnection of all conductors, enhancing safety in 3-phase systems with neutral.
• Exact part reference ensures dependable compatibility with Eaton panelboards and distribution setups that require KD4200.
• Medium-voltage-ready profile tailored for industrial environments, balancing performance with durable construction.

Ideal use cases

• Retrofitting aging panelboards to restore full 3-phase protection without changing downstream components.
• Replacing a failed or obsolete breaker in maintenance shutdowns where exact specifications are critical.
• Upgrading power distribution in manufacturing floors, data centers, and other facilities that rely on reliable 600V protection.
• Installing or refurbishing systems that require a four-pole breaker for complete fault isolation and safer de-energization.

Compatibility and ordering guidance

Important: Confirm fit and ratings before ordering. The part number is the best reference for compatibility. If your system specifies KD4200, this breaker will align with the protection, sizing, and trip characteristics required by your Eaton-based installation.

Practical installation and care tips

• Ensure power is fully isolated before attempting any replacement or retrofit work.
• Verify that the panel and bus configuration match a 4-pole, 200A, 600V specification before installation.
• Follow manufacturer torque and alignment guidelines for lugs and mounting to maintain electrical integrity.
• Conduct a post-installation test to confirm proper operation and trip behavior within the system’s protection scheme.

Whether you're refreshing an aging distribution path, performing a strategic retrofit, or performing a precise replacement, the Eaton KD4200 provides clear compatibility, solid protection, and the reliability required for critical electrical infrastructure.
