Product description

The Eaton GD3045 is a 3-pole molded case circuit breaker rated at 45A and 480V, built to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Designed for reliability in demanding electrical layouts, it provides precise, predictable protection for your three-phase circuits.

  • Compact molded case design maximizes panel space without compromising protection, helping you fit more circuits into a single enclosure.
  • Thermal-magnetic trip unit delivers stable, repeatable protection by quickly interrupting on high fault currents while smoothly handling overloads for long-term reliability.
  • OEM compatibility is preserved with seamless matching to Eaton loadcenters and panelboards, enabling straightforward installation and maintenance without panel rewiring.
  • 3-pole, 480V operation makes it ideal for 3-phase distribution in commercial and light industrial environments, as well as certain residential applications that require three-phase protection.
  • 45A current rating provides targeted protection for branch circuits feeding motors, lighting, and equipment where moderate load and fault tolerance are essential.

Who should consider the GD3045? installers and electrical professionals looking to upgrade or expand panelboards and loadcenters with a compact, reliable 3-pole breaker. It’s particularly well-suited for commercial spaces, light industrial facilities, and residential projects that leverage three-phase distribution or need a robust disconnect option within a panel.

Why choose this Eaton solution over alternatives? The combination of a compact form factor, a trusted thermal-magnetic trip mechanism, and explicit compatibility with Eaton OEM panels reduces installation risk and helps ensure coordinated protection across your electrical system. The result is safer, more predictable performance for your distribution panels and a clearer path to compliance with standard electrical protection practices.
