Schneider Electric QOT1515 Twin Tandem Circuit Breaker

Schneider Electric's Square D QOT1515 tandem circuit breaker is a plug‑in device that provides two 15 A, single‑pole circuits in the space of a single breaker slot. It is rated for 120/240 VAC with a 10 kA short‑circuit current rating, enabling two circuits in panels that accept tandem breakers. Each pole is rated at 15 A for typical branch circuit loads such as lighting, outlets, or other standard residential circuits. The QOT1515 is part of the QO family’s tandem options; for a two‑pole configuration, you can install two QOT1515 units and use a QOTHT handle tie to achieve common switching of the center pair. This tandem breaker is a plug‑in device intended for panels that explicitly permit tandem breakers, and it should be used only in positions designated for QOT tandems by the panel manufacturer. When installed in compatible equipment, the QOT1515 helps maximize circuit capacity without increasing the overall footprint of the panel.
