Eaton / Cutler-Hammer QBGFEP2030 GFEP Miniature Circuit Breaker

The QBGFEP2030 is designed for bolt-on installation in Eaton and Cutler-Hammer Pow-R-Line panelboards, including PRL1a, PRL2a, PRL1X, and PRL2X models.

This breaker features a 30mA trip sensitivity, classifying it as Ground Fault Equipment Protection (GFEP). It protects machinery and cables from damaging line-to-ground faults but does not provide the 5mA Class A protection required for personnel safety.

Installation requires terminating your load neutral to the breaker and connecting the factory-installed pigtail neutral directly to the panelboard neutral bar. This completes the circuit required to power the internal ground fault monitoring electronics.

No. Eaton acquired Cutler-Hammer, and the QBGFEP2030 catalog number remains identical under both brandings. Both versions are physically and electrically identical.

It utilizes a bolt-on connection standard to the BAB frame and Quicklag family. You must physically bolt the breaker terminals to the panel busbars, which provides a highly secure connection for commercial and industrial environments.

GFEP breakers like the QBGFEP2030 are commonly specified for heat trace cables, snow melting equipment, and industrial machinery. The higher 30mA threshold prevents nuisance tripping caused by standard capacitive leakage in these systems.

The LIG designation confirms this breaker provides Long-Time overload, Instantaneous short-circuit, and Ground Fault protection. The thermal magnetic components handle standard overcurrents, while the GF electronics monitor for leakage.

No. This breaker has a maximum interrupting rating of 10kAIC at 240VAC. It cannot be installed in commercial or industrial systems where the available short-circuit current exceeds 10,000 amps.
