QO Series 15 A Two-Pole Breaker

This miniature circuit breaker belongs to the Square D QO series and carries a 15 A rating with a 120/240 V AC voltage rating. It uses a switched-neutral design with two poles and a paddle actuator for manual control. The unit is built for plug-in mounting inside compatible QO load centres and NQ panelboards. It suits residential or light-commercial branch circuits requiring neutral switching.

10 kA Interrupting Rating Thermal Performance

The breaker delivers a maximum AIR rating of 10 kA at 120/240 V AC, providing reliable short-circuit protection for the circuit. Thermal tripping responds to sustained overloads without external cooling requirements. The paddle actuator gives a clear visual indication of the on, off or tripped position. No DC voltage rating is assigned, so the device is limited to AC applications.

Pressure-Plate Terminals Plug-In Frame

Terminal connections use pressure-plate clamps that accept solid or stranded conductors for secure attachment. The plug-in mounting style engages directly with the bus bars of a QO load centre, simplifying installation and removal. Frame size is rated at 100 A, matching standard QO panel dimensions. Physical measurements are 3 in length, 1.5 in width and 2.91 in depth for panel planning.

Questions about this item

How do I install the QO215SWN in a QO load center, and what step is often missed?

Align the plug-in base with the bus stabs, press firmly until it seats fully, then verify the paddle actuator moves freely; the step often missed is confirming the breaker is fully latched on both poles.

What maintenance or replacement will the QO215SWN need over time?

No routine maintenance is required; replace the breaker if it trips repeatedly without overload, shows discoloration at the pressure-plate terminals, or fails to reset cleanly after a fault.

What limit appears first when the QO215SWN runs at 15 A continuously?

The 10 kA interrupting rating at 120/240 V AC is the first hard limit; sustained loads above 15 A will trip the thermal-magnetic element before the AIR rating is reached.
