Eaton LD3350C - 350 A, 600 V, 3-Pole Circuit Breaker | AmpState

Eaton LD3350C is a 350A, 600V, 3-pole molded case circuit breaker engineered to deliver reliable protection for branch circuits in panelboards and load centers. When space and dependable protection matter, this unit provides a compact, space-efficient solution without compromising safety or performance.

• Space-efficient design: A compact molded case construction helps maximize panel space, making it easier to fit into dense panels and multi‑circuit layouts.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection by combining thermal and magnetic trip mechanisms to respond precisely to overcurrent and short-circuit conditions, reducing nuisance trips across varying temperatures and loads.
• 3-pole configuration: Ensures simultaneous, coordinated tripping across all three phases, which is essential for balanced three-phase systems and protects equipment connected to multi‑phase feeders.
• Broad compatibility: Designed to be compatible with matching OEM loadcenters and panelboards, promoting reliable fit, terminal integrity, and straightforward replacement in Eaton‑compatible systems.
• Versatile applications: Suitable for residential, commercial, and light industrial applications where robust branch circuit overcurrent and short‑circuit protection is required.

Why this matters

In service panels and distribution boards, every breaker must respond correctly to faults while avoiding unnecessary interruptions. The LD3350C’s thermal-magnetic design provides predictable trip characteristics, helping you protect feeders, equipment, and occupants without sacrificing uptime. Its three-pole format is ideal for three‑phase installations, such as commercial service panels and light industrial distribution, where coordinated protection is critical.
