Product FAQs

5 answers
Which panelboards are compatible with the QBGF2050?

This breaker is designed for use in Eaton Pow-R-Line and Quicklag panelboards that accept bolt-on BAB frame breakers.

What is the ground fault trip sensitivity for this breaker?

The QBGF2050 features a 5mA trip threshold, providing Class A ground fault protection for personnel in wet or damp locations.

What is the difference between the QBGF2050 and the QBGFT2050?

The QBGF2050 is the legacy version, while the QBGFT2050 is the newer direct replacement that includes an auto-monitoring self-test feature. Both share the same physical dimensions and panel compatibility.

    Pleasantly Surprised!

    Items came new, in factory boxes. Well packaged, not damaged.

    Someone cared when the order was picked and packaged that says a lot.

    Thanks

    Got an Eaton "BR" type 2 pole 30A bolt-in GFI breaker. OEM packaging and paperwork inside. Would buy from them again.
