Eaton GD3030 - 30 A, 480 V, 3-Pole Circuit Breaker | AmpState

Engineered for dependable branch-circuit protection in panelboards and load centers, the Eaton GD3030 delivers reliable 30A, 480V, 3-pole protection. Its compact molded-case design maximizes panel space, making it ideal for installations where enclosure real estate is at a premium. A thermal-magnetic trip unit provides stable, repeatable protection across varying loads and temperatures, helping prevent nuisance trips while still delivering fast response during fault conditions.

Why the GD3030 stands out

• Compact molded-case construction optimizes panel space and simplifies wiring within tight enclosures.
• Thermal-magnetic trip combines precise overload sensing with magnetic instantaneous trip for rapid fault interruption.
• 30 A at 480 V, 3-pole design tailored for higher-voltage commercial and light-industrial circuits.
• OEM-ready compatibility built to pair with matching load centers and panelboards from Eaton and other manufacturers.
• Versatile across environments suitable for residential, commercial, and light-industrial applications requiring dependable protection.

How protection works in real-world systems

The GD3030 guards conductors and connected equipment by interrupting current when overcurrent or short-circuit conditions arise. The thermal element responds to sustained overloads, while the magnetic element trips instantly on high-energy faults, reducing equipment damage and downtime in critical electrical systems.

Ideal use scenarios

• New installations in office buildings, retail spaces, and light-industrial facilities that operate at 480V and demand reliable, code-compliant protection.
• Upgrading or replacing aging or undersized breakers in existing panelboards where space is limited but protection must remain robust.
• Applications requiring consistent trip performance across temperature variations and load fluctuations.
