Questions about this item

What does the 18 kA interrupting rating mean once the breaker is installed in a panel?

It means the breaker can safely clear a short-circuit current up to 18 000 amps at 277/480 V AC without damage, protecting downstream wiring and equipment.

How does the bolt-on mounting style limit the panels this breaker can be used in?

The bolt-on design only fits Square D NF series panelboards; it will not snap into QO, Homeline or other load-centre rails.

What are the exact dimensions I need to clear for this 3-pole unit in the enclosure?

The breaker measures 5.66 in long, 2.94 in wide and 4.05 in deep, so allow at least that much space plus wiring bend radius.
