Schneider Electric QO3015 30/15A Tandem Miniature Circuit Breaker

This breaker is designed for Square D QO load centers, NQ panelboards, and NQOD panelboards. As a non-CTL breaker, it is intended for older panels that do not have notched bus bars.

No. Because the QO3015 is a non-CTL tandem breaker, it lacks the rejection clip found on CTL breakers. It is designed specifically as a replacement for older panels that accept non-CTL tandems.

No. The QO3015 is exclusively for Square D QO series panels. Homeline panels require Homeline series breakers.

Both models provide one 15A and one 30A circuit in a single pole space. The QO3015 is a direct substitute for the QO1530, with the only difference being the physical arrangement of the 15A and 30A toggles.

Yes. Square D is a brand owned by Schneider Electric. The QO3015 may be labeled under either name, but the physical breaker and its certifications are identical.

The box lugs are rated for both copper and aluminum conductors, accepting wire sizes from 14 AWG up to 8 AWG.

This tandem breaker provides two independent circuits, one 15A and one 30A, while only occupying a single one-pole space in the panel.

The LI designation indicates that the breaker uses thermal-magnetic trip technology, providing Long-Time thermal protection against overloads and Instantaneous magnetic protection against short circuits.

Yes. The QO3015 is HACR rated, meaning it is approved for use with compatible heating, air conditioning, and refrigeration equipment.

Yes. It features the Square D Visi-Trip indicator, which displays a highly visible red flag when the breaker trips, making it easy to identify the tripped circuit in a crowded panel.

No. This is a standard thermal-magnetic breaker. It does not include GFCI or AFCI protection.
