Eaton MDL3500 - 500 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton MDL3500 — a rugged 3-pole molded case circuit breaker designed to deliver reliable branch circuit protection in panelboards and loadcenters. With a compact footprint and a thermal-magnetic trip unit, this breaker provides stable, repeatable protection for everyday electrical systems in residential, commercial, and light industrial settings.

Key features that set the MDL3500 apart

• Compact molded-case design maximizes panel space, making it easier to fit into tight electrical enclosures without sacrificing performance.
• Thermal-magnetic trip unit delivers dependable protection by responding to both overloads (thermal) and short circuits (magnetic) for faster, more predictable interrupting action.
• Three-pole configuration ensures synchronized protection across all phases, reducing arc risk and helping maintain system balance in 3‑phase applications.
• OEM-loadcenter compatibility designed to integrate with matching Eaton OEM loadcenters and panelboards, simplifying installation and replacement.

Why this matters for your electrical system

Choosing the MDL3500 means selecting a breaker that aligns with real-world needs: robust protection without demanding extra space, resilient performance in daily operations, and straightforward compatibility with familiar paneling ecosystems. The 3‑pole design is especially beneficial for 3‑phase circuits common in commercial and light industrial environments, where consistent interruption across all conductors minimizes potential fault propagation and downtime.

Ideal use cases

• Upgrading or replacing breakers in residential or light commercial panelboards where 3‑phase protection is required.
• Installing new branch circuits in commercial spaces that rely on reliable overcurrent and short-circuit protection.
• Retrofits in OEM panel centers where seamless compatibility with existing loadcenter hardware reduces installation complexity.
