Product FAQs
6 answersHow many panel spaces does the Square D HOM2175BB require?
Although it is a 2-pole breaker, the HOM2175BB requires 4 standard 1-inch spaces in a Square D Homeline load center due to its physical width and high amperage rating.
Can I install the HOM2175BB in a Square D QO load center?
No. The HOM2175BB features a plug-on mounting design that is exclusively compatible with Square D Homeline load centers. It will not fit in Square D QO panels or load centers from other manufacturers.
Is the HOM2175BB suitable for heating and air conditioning loads?
Yes, this circuit breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
How does the thermal-magnetic trip unit protect the circuit?
The thermal-magnetic mechanism provides dual-level protection. The thermal element responds to sustained overloads by heating and tripping the breaker, while the magnetic element reacts instantaneously to severe short circuits.
What is the UPC for the Square D HOM2175BB?
The standard UPC for this Homeline 175A miniature circuit breaker is 785901264477.
What are the typical applications for a 175A Homeline breaker?
A 175A breaker like the HOM2175BB is frequently used as a main breaker, to feed a large subpanel, or to protect high-amperage branch circuits in residential and light commercial electrical systems.

My pool motor stopped running, and I found a breaker fault causing the problem. I could not find one locally, and SuperBreakers had a reasonable price with free delivery. I called and asked where they were located, as I wanted it ASAP. The New York gentleman I spoke with checked his inventory and said it would go out that afternoon. When it arrived, it was a snap to get my motor running again.

I was having a hard time finding this partifcular breaker at my local big box building materials retailer and found this and another odd size breaker. Much better price here and shipped in a couple of days. Could not be happier. I will think of this company for future projects.

- HMHope M.Verified BuyerReviewingSquare D HOM220 - 20A 2 Pole Miniature Circuit BreakerI do not recommend this productRated 1 out of 5 stars4/1/26Deceiving
I needed a specific breaker that has a large opening for the wiring. The photos were deceiving and showed what looked like the large opening I need for where the wires go. However, I received the breaker and the opening is the exact same and 2 other breakers I purchased from Home Depot and from Menards. Now I spent another $35 on a breaker I can’t even use. Shopping is outrageously priced, and I tried to return and I literally will have to PAY THEM to return this item. I’m very upset.
