Eaton QCGF1030 - 30 A, 120 V, 1-Pole Circuit Breaker | AmpState

The Eaton QCGF1030 is a compact, dependable 1-pole molded case circuit breaker designed to protect branch circuits in panelboards and load centers. With a 30A rating at 120V, this unit delivers reliable overcurrent and short-circuit protection where it matters most—without taking up unnecessary space in the panel.

Key to its performance is the thermal-magnetic trip unit, which combines precise thermal sensing for sustained overloads with magnetic tripping for immediate response to short circuits. The result is stable, repeatable protection across a wide range of temperatures and electrical conditions, reducing nuisance trips and helping keep sensitive loads safe.

Designed for seamless compatibility, the QCGF1030 works with matching OEM load centers and panelboards, making it a smart replacement or upgrade option for residential, commercial, and light-industrial applications. If you’re updating an existing distribution setup or stocking spare breakers for service calls, this unit fits the bill where a single-pole, 30A protection device is required.
