Eaton / Cutler-Hammer QCGFT1015 GFCI Miniature Circuit Breaker

No. The QCGFT1015 features a cable-in/cable-out feed-thru design, which does not connect to a standard residential panel busbar. It is designed specifically for Eaton Quicklag enclosures and OEM control panels configured for front-connected QC-frame breakers.

The primary difference is the enclosure connection style. The QPGFT is a plug-on breaker, the QBGFT is a bolt-on breaker, and the QCGFT is a cable-in/cable-out breaker. You must verify the mounting requirements of your specific panel before selecting the QCGFT1015.

Instead of mounting directly onto a live panel busbar, this feed-thru breaker is front-connected. Both the incoming line power and the outgoing load conductors are wired directly into the box lugs located on opposite ends of the breaker.

Yes. The coiled white pigtail wire must be landed on the panel or enclosure neutral bar. This connection completes the circuit required to power the internal electronics for the ground-fault monitoring system.

The QCGFT1015 provides Class A personnel protection with a 5mA trip sensitivity. It actively monitors the circuit for leakage current to ground and trips to prevent severe electrical shocks in wet or damp environments.

LIG stands for Long-Time, Instantaneous, and Ground-Fault. This indicates the breaker utilizes a thermal-magnetic mechanism for standard overload and short-circuit protection, alongside active leakage current monitoring for personnel safety.

The QCGFT1015 includes an integrated push-to-test button on the front face of the breaker. Once the circuit is energized, pressing this button safely simulates a ground fault to verify that the 5mA trip mechanism is fully operational.

Yes. Eaton acquired Cutler-Hammer and integrated their circuit breaker product lines. A QCGFT1015 branded as Eaton is the exact same component in form, fit, and function as one bearing the older Cutler-Hammer label.
