Product FAQs
6 answersWhich panelboards are compatible with the Eaton QBHW3030HT circuit breaker?
This bolt-on breaker is designed for use in Eaton Pow-R-Line panelboards, specifically PRL1a models that are configured to accept BAB and QBHW frame types.
Can I install QBHW3030HT breakers on the same subchassis as GHB breakers?
No. Eaton specifications state that GHB, HGHB, and GHQ breakers cannot be mixed on the same subchassis as BAB or QBHW breakers. Panels containing only BAB or QBHW branch breakers require a PRL1a panelboard.
Can I use the QBHW3030HT to replace a standard BAB breaker?
Yes, the QBHW3030HT shares the same physical footprint as a standard BAB breaker but offers a higher interrupting rating of 22kAIC at 240V, compared to the 10kAIC rating of standard BAB breakers. It is suitable for systems requiring higher fault current protection.
What type of wire connections does the QBHW3030HT support?
The breaker features stud or tapped pad terminals that accommodate copper or aluminum conductors ranging from 14 AWG to 4 AWG. Always verify proper torque specifications during installation to ensure a secure connection.
How does the thermal-magnetic trip mechanism operate on this breaker?
The QBHW3030HT features a fixed thermal-magnetic trip unit. The thermal component provides long-time protection by tripping during sustained overloads, while the magnetic component offers instantaneous protection to quickly clear short circuits.
Are Cutler-Hammer and Eaton QBHW3030HT breakers the same?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse electrical distribution lines. Breakers labeled under any of these three brands with the QBHW3030HT catalog number are identical and fully interchangeable.
