Eaton | KD4225W | Circuit Breaker | 225A | 4-Pole | 600V

The Eaton KD4225W Circuit Breaker is a robust solution for protecting large electrical feeders and demanding 3-phase systems. With a 225 A rating and a 4-pole design, it provides reliable, simultaneous disconnection across all conductors in distribution panels up to 600 V, helping prevent arc flash and equipment damage during faults.

This unit is purpose-built for maintenance, retrofit, and replacement projects where exact specifications matter. The part number KD4225W is the most reliable reference to ensure compatibility with your Eaton equipment and existing KD-series infrastructure.

• Four-pole design enables full disconnect of all live conductors in multi-wire, 3-phase systems, enhancing safety during trips and servicing.
• 225 A current rating suits main feeders and substantial loads without over- or under-protection.
• 600 V maximum system voltage broadens applicability across industrial distribution panels, switchgear, and control centers.
• Real-world reliability built on Eaton engineering, designed for consistent performance in busy, high-demand environments.

Ordering and compatibility tips

Note: Confirm fit and ratings before ordering. The KD4225W part number is the best reference for compatibility with your current Eaton installation. If your panel or switchgear specifies a KD-series breaker, this unit is designed to align with those specifications to ensure proper mounting, trip performance, and electrical characteristics.

Practical considerations for installation and use include following standard electrical practices, verifying the panel’s capacity for a 4-pole, 225 A, 600 V device, and keeping a spare KD4225W on hand for future retrofit projects. This approach minimizes downtime and keeps your electrical distribution running smoothly and safely.
