Eaton | HND3800T107W | Circuit Breaker | 800A | 3-Pole | 600V

The Eaton HND3800T107W circuit breaker is built for industrial reliability when protection of high‑current, three‑phase power is non‑negotiable. Rated for 800A and designed for 600V systems, this three‑pole device delivers robust overcurrent protection that keeps heavy motors, feeders, and critical loads running smoothly in demanding environments.

Key specifications at a glance

• Amperage: 800A
• Poles: 3‑Pole
• Voltage: 600V

What sets this Eaton breaker apart

• Specialized for maintenance, retrofit, and replacement: When upgrading legacy panels or refreshing worn protective devices, the HND3800T107W provides a seamless fit with established Eaton systems, minimizing downtime and rework.
• Three‑phase, high‑current protection: A true three‑pole design ensures balanced protection across all phases, reducing unbalanced faults and protecting connected motors and equipment from damaging faults.
• Clear compatibility reference: The part number HND3800T107W is the most reliable reference for matching panels and switchgear—use it to verify fit before ordering.

Ideal use cases

• Upgrading or replacing protection in large industrial panels that serve heavy machinery, conveyors, or processing lines.
• Retrofits where existing equipment requires a like‑for‑like 800A, 3‑pole, 600V protective device to maintain system performance and safety.
• Maintenance inventories to ensure quick, accurate replacements with minimal panel disruption.

Why this matters for your operation

With an 800A rating, this Eaton breaker is purpose‑built for high‑demand feeders. The 3‑pole configuration supports balanced protection across all phases, helping to prevent phase imbalances that can wear motors prematurely. Paired with 600V systems, it’s well suited for industrial environments where reliability and uptime are essential—think manufacturing floors, power distribution rooms, and large‑scale mechanical systems.

How to ensure the right fit

Before you order, confirm the breaker’s fit and ratings against your panel or switchgear label. Rely on the part number—HND3800T107W—as the best compatibility reference. If you’re replacing an existing Eaton device, verify the same ampacity, polarity, and voltage range to maintain protective coordination and safe, predictable trip behavior.

Practical tips for installation and use

• Match the breaker’s three‑pole design to your 3‑phase feeders to ensure cohesive protection across all lines.
• Document the replacement in your maintenance logs with the exact part number to simplify future retrofits or audits.
• Store on hand with other compatible Eaton protection devices to speed up downtime‑critical replacements.
