Eaton | HKD3350W | Circuit Breaker | 350A | 3-Pole | 600V

Engineered by Eaton, the HKD3350W circuit breaker is built for robust protection in demanding 3-phase power systems. With a 350A rating and three poles, this unit is purpose-built for 600V distributions in industrial, commercial, and retrofit environments.

• Amperage: 350A
• Poles: 3-Pole
• Voltage: 600V
• Part reference: HKD3350W — use this number to verify compatibility and fit
• Application: maintenance, retrofit, and replacement where matching specs are required

Why choose this model? It is designed to align with Eaton system requirements, providing cohesive protection across your panel and minimizing mismatch risks during upgrades. The 3-pole design ensures synchronized disconnection across all phases, improving safety and fault clearance in 3-phase networks.

Practical use cases

• Retrofits in factories upgrading to higher-current feeders without changing the surrounding panel infrastructure.
• Repairs in data centers or manufacturing floors where large motors and heavy loads demand reliable 350A protection at 600V.
• Maintenance cycles in commercial buildings with Eaton-based panels seeking a direct replacement part.

Installation notes and care: Before ordering, confirm fit by cross-checking the HKD3350W part number against your panel’s documentation. Ensure the system voltage and conductor sizing align with 600V and 350A requirements, and follow local electrical codes during installation. When in doubt, consult a licensed electrician to review panel compatibility and trip characteristics for your specific load profile.

With the Eaton HKD3350W in service, you gain a dependable, directly replaceable breaker that supports predictable protection outcomes, reduces maintenance surprises, and keeps heavy 3-phase loads safeguarded against overloads and short circuits.
