Schneider Electric QOT115 Molded Case Circuit Breaker

Schneider Electric's QOT115 is a QOT-series molded‑case circuit breaker rated for 15 A in a 1‑pole configuration, designed for use in panels that accept tandem breakers to increase circuit density in a single slot. As a tandem unit, the QOT115 provides protection for an additional circuit within the same physical footprint, a configuration typical in CTL‑marked Square D panelboards that require space optimization. Schneider Electric notes that QOT tandem breakers (the QOT family) are not compatible with plug‑on neutral systems, so it must be installed only in panels that support CTL tandems. The QOT line sits within the Square D family of molded‑case breakers used in residential and light commercial distribution, and is intended for use wherever a 15‑amp, single‑pole tandem breaker is specified by the panel manufacturer.
