Eaton | LDB3500W | Circuit Breaker | 500A | 3-Pole

Meet Eaton's LDB3500W, a genuine 500A, 3‑pole circuit breaker designed to protect high‑demand electrical circuits in commercial and industrial settings. Crafted with retrofit, maintenance, and replacement projects in mind, this unit helps you restore reliable protection without compromising compatibility.

Key specifications

• Part number: LDB3500W
• Amperage: 500A
• Poles: 3‑Pole (three‑phase protection)
• Application: Circuit protection for maintenance, retrofit, and replacement needs

Why choose the LDB3500W

Having the exact part number matters because compatibility across Eaton panels and assemblies is built around this reference. The LDB3500W is a purpose‑built solution for 3‑phase distribution systems, designed to slot into Eaton‑certified panels where 500A protection is required. This is not a generic substitute—it's a precise, reliable component that supports minimal downtime and consistent tripping performance when faults or overloads occur.

Compatibility and fit checks

Important: Confirm fit and ratings before ordering. The part number is the best reference for compatibility, so cross‑check LDB3500W with your panel’s documentation or Eaton‑compatible catalogs. If your system uses the LDB family, this unit aligns with the same compatibility ecosystem and trip characteristics.

Ideal use scenarios

• Upgrading legacy installations to a robust 500A, 3‑pole protection scheme in retrofit projects
• Replacing a failed 3‑pole breaker in commercial or light industrial panels
• Consolidating critical feeders into a single, reliable 500A protection point for enhanced system resilience

What to expect in practice

With the LDB3500W, you gain a dependable, Eaton‑spec component designed to maintain electrical safety and uptime in demanding environments. Ensure proper pairing with compatible Eaton bus assemblies and enclosures to preserve coordination with upstream protection devices and downstream feeders for smooth, safe operation.
