Square D HOM280 80 A Breaker

The Square D HOM280 is a miniature circuit breaker rated at 80 amps for 120/240 V AC single-phase service. It belongs to the Homeline series and uses a two-pole paddle actuator that plugs directly into compatible Homeline load centres.

10 kA Interrupting Rating

The breaker carries a maximum AIR rating of 10 kA at 120/240 V AC, which is the key figure for deciding whether it meets the available fault current at the installation point. It has no DC voltage rating and is built on a 100 A frame with lug terminals.

For Homeline Panels Needing 80 A Protection

Electricians fitting an 80 A two-pole circuit in a Square D Homeline load centre will find this breaker matches the required mounting style and series. Installers working with other panel brands, DC circuits, or applications demanding a higher interrupting capacity should look at alternative products.

Questions about this item

How much current does the 80 A rating actually let through in a home panel?

The breaker carries up to 80 A continuously on each of its two poles and will trip only when the load exceeds that value.

What does the 10 kA AIR rating limit in a fault condition?

It means the breaker can safely interrupt a short-circuit current of up to 10 kA at 120/240 V AC without damage.

Will the 3.1 in length fit my Homeline load centre?

Yes, the plug-in frame is designed for Homeline panels and occupies two standard pole spaces measuring 3.1 in long by 2 in wide.
