Eaton HMDL3350 - 600 V, 3-Pole Circuit Breaker | AmpState

Introducing the Eaton HMDL3350 — a 600V, 3-pole molded-case circuit breaker engineered to deliver dependable branch-circuit overcurrent and short-circuit protection in panelboards and loadcenters. Whether you’re wiring a residential panel, a small commercial installation, or light industrial equipment, this breaker provides precise, repeatable protection while making efficient use of panel space.

Why choose the Eaton HMDL3350?

• Compact molded-case design saves valuable panel space and simplifies layout, letting you fit more circuits without crowding the enclosure.
• Thermal-magnetic trip unit delivers stable, repeatable protection: the thermal element handles sustained overloads, while the magnetic element responds rapidly to short circuits for fast interruption.
• 3-pole configuration ideal for 3-phase systems and multi-wire branch circuits, ensuring coordinated protection across all phases.
• OEM-compatible designed for use with matching Eaton OEM loadcenters and panelboards, ensuring a clean fit, consistent mounting, and matching trip characteristics.
• 600V rating broadens applicability for residential, commercial, and light industrial distribution.
• Versatile applications suitable for new installations, panel upgrades, or service equipment in a variety of settings.

Who this is for

Electrical professionals, facility managers, and contractors who require reliable, long-lasting protection for 3-phase or multi-wire distributions in panelboards and load centers. The HMDL3350 helps meet safety standards while maintaining electrical system integrity without sacrificing space.

What makes it different from generic breakers

Unlike smaller or single-pole breakers, the HMDL3350 combines a compact molded-case design with a thermal-magnetic trip that provides both space efficiency and precise protection. This means fewer nuisance trips and robust performance during faults, all within compatible OEM panel environments.
