Key specifications at a glance
  • Amperage: 400A
  • Poles: 3‑Pole
  • Voltage: 600V
  • Reference compatibility: Part number HLD3400X is the best reference for matching equipment
  • Important note: Confirm fit and ratings before ordering
Why this matters for your project

When upgrading or replacing protection hardware in a 3‑phase 600V system, selecting the exact model ensures the electrical characteristics align with your existing gear. The HLD3400X is purpose‑built to slot into panels and configurations that require a 400A, 3‑pole device, helping to maintain coordinated protection and trip behavior across all phases. Using the precise part number minimizes mismatch risk and reduces the time spent on compatibility checks during installation.

Ideal use cases
  • Maintenance: Replace aging or failed breakers to restore reliable overcurrent protection
  • Retrofit: Upfit existing 3‑phase distribution panels to current specifications without changing ancillary hardware
  • Replacement: Swap out a like‑for‑like unit to maintain system continuity after maintenance outages
  • New installations requiring exact Eaton HLD3400X compatibility for a 600V, 3‑phase supply
Practical considerations

To ensure seamless integration, rely on the part number HLD3400X as the definitive reference for compatibility. Before placing an order, cross‑check your panel’s label and mounting configuration against the 3‑pole, 400A, 600V rating to avoid delays. This approach helps you achieve consistent protection performance and minimizes the risk of mismatched components in critical electrical infrastructure.
