Eaton / Cutler-Hammer QBHW2030 Miniature Circuit Breaker

The QBHW2030 is a Quicklag bolt-on breaker designed for Eaton, Cutler-Hammer, and legacy Westinghouse Pow-R-Line panelboards. It is commonly used in PRL1a, PRL1X, and PRL2X series panels configured for bolt-on branch circuit breakers.

The primary difference is the short-circuit interrupting rating. The standard BAB2030 is rated at 10kAIC at 240V, while the QBHW2030 is rated at 22kAIC. Both share the exact same physical dimensions and bolt-on mounting style. The QBHW2030 is typically used when the electrical system requires a higher interrupting capacity.

No. The QBHW2030 is a bolt-on miniature circuit breaker meant for commercial and industrial panelboards. It cannot be installed in standard residential load centers, which typically require plug-on breakers like Eaton Type BR or Type CH.

Yes. Eaton acquired Cutler-Hammer and continues to manufacture these breakers to the exact same specifications. A new Eaton QBHW2030 is a direct, UL-listed replacement for an older Cutler-Hammer breaker with the same catalog number.

Yes. Eaton acquired the Westinghouse electrical distribution division. The current Eaton QBHW2030 serves as a direct, UL-listed replacement for legacy Westinghouse 30-amp, 2-pole QBHW breakers.

No. The QBHW2030 is a standard thermal-magnetic circuit breaker that provides only overload and short-circuit protection. It does not include GFCI or AFCI capabilities. If your application requires 22kAIC ground fault or arc fault protection, you will need a specialized Quicklag breaker, such as a QBHGFT or QBHAF model.
