Product FAQs

7 answers
What type of panelboards are compatible with the QBHW3020HT circuit breaker?

This bolt-on breaker is designed for use in Eaton and Cutler Hammer Pow-R-Line 1 (PRL1a) and Pow-R-Line 2 (PRL2a) panelboards that accept Quicklag BAB or QBHW frame breakers.

Can I use a BAB3020 instead of the QBHW3020HT?

The BAB3020 has a lower interrupting rating of 10 kAIC, whereas the QBHW3020HT is rated for 22 kAIC. You can only substitute a BAB breaker if your system's available fault current is 10 kAIC or less. If the panel requires a 22 kAIC rating, you must use the QBHW series.

How does the QBHW3020HT connect to the panel bus?

It features a bolt-on connection where the breaker is physically bolted directly to the panelboard bus bars. This provides a secure, vibration-resistant connection commonly required in commercial and industrial applications.

Is the QBHW3020HT suitable for HVAC equipment?

Yes, Eaton Quicklag miniature circuit breakers in this class are HACR rated, meaning they are approved for use with heating, air conditioning, and refrigeration equipment.

What wire size does the QBHW3020HT accept?

The terminals on this 20A breaker accept #14 to #4 AWG copper or aluminum wire.

How much panel space does the QBHW3020HT require?

As a 3-pole Quicklag breaker, it requires three 1-inch spaces in the panelboard, for a total width of 3 inches.

Are Eaton and Cutler Hammer QBHW3020HT breakers the same?

Yes. Eaton acquired Cutler Hammer and continues to manufacture the Quicklag series under the Eaton brand. A QBHW3020HT labeled Eaton is an exact, direct replacement for an older Cutler Hammer model.
