Miniature Circuit Breaker 15A 2 Pole

The SQUARE D QOB215 is a miniature circuit breaker rated at 15 A for 120/240 V AC systems. It uses a bolt-on mounting style and fits QO series panelboards. The two-pole design protects a single-phase circuit. A paddle actuator provides manual switching.

Electrical contractors and panel builders

This breaker suits installers fitting or maintaining Square D NQOD panelboards that accept QO series devices. It is not for panels requiring plug-on mounting or a different frame size. Buyers needing a higher interrupting rating or a different pole count should look at other models.

Sustained load behaviour

The device carries its 15 A rating continuously within the listed 77 °F minimum operating temperature. Its 10 kA interrupting capacity at 120/240 V AC handles fault conditions without nuisance tripping. Pressure-plate terminals maintain secure connections under thermal cycling. The compact frame fits standard QO panelboard spacing.

Questions about this item

Does this QOB215 breaker require a Square D QO-series panelboard with bolt-on mounting?

Yes, it is designed for Square D NQOD panelboards and uses a bolt-on mounting style with pressure-plate terminals.

Will the 10 kA interrupting rating at 120/240 V AC coordinate with older 15 A single-pole breakers in the same load centre?

The 10 kA AIR rating applies to this two-pole device; coordination with existing single-pole breakers depends on the panelboard’s series rating and should be verified by an electrician.

How can I confirm the breaker is operating correctly after installation?

With the paddle actuator in the ON position, measure 120 V from each pole to neutral and 240 V between poles under load; the breaker should remain closed up to 15 A per pole.
