Product identity
The Square D HOM240 is a 40 A two-pole plug-in miniature circuit breaker rated for 120/240V AC. It fits Homeline load centers and protects single-phase branch circuits up to a 10 kA interrupting rating at that voltage.
What the bundle changes
This breaker installs directly into compatible Homeline panels without additional mounting hardware. The plug-in style and lug terminals simplify wiring, while the paddle actuator provides clear on/off indication for maintenance or emergency shutdown.
Before you order
Verify the load center is a Homeline series with available two-pole space and a 100 A frame rating. Confirm the circuit requires 40 A protection at 120/240V AC and that the panel can accommodate the 3.13 in length, 2.0 in width and 2.98 in depth of the breaker body.

Questions about this item
Will the 40 A breaker itself need replacement after it trips?
The HOM240 is a reusable thermal-magnetic breaker; it resets after a trip and only needs replacement if the mechanism wears out or the unit is damaged.
What is the maximum fault current the 2-pole HOM240 can interrupt?
The breaker carries a 10 kA AIR rating at 120/240 V AC, so sustained fault currents above 10 000 amps exceed its interrupting capacity.
How much heat does the 40 A two-pole breaker add inside a Homeline load center during continuous operation?
At full 40 A load the breaker dissipates a few watts; the load-center ventilation handles this heat, and the 104 °F minimum operating temperature shows the unit is rated for warm panel interiors.
