QOT1515CP Tandem Mini Circuit Breaker – Square D QO, 2x1-Pole, 15A, 120/240V, 10kA

Upgrade your panel efficiency with the Square D by Schneider Electric QOT1515CP tandem mini circuit breaker. This 2-in-1 device combines two 15-amp circuits into the space of a single pole, helping you maximize capacity in crowded panels while maintaining reliable overload and short-circuit protection for your electrical system. Rated for 120/240 VAC and an impressive 10,000 air- and interrupting rating, this breaker is built to handle everyday loads with confidence.

Designed for use in QO load centers, CSED devices, and NQOD panel boards, the QOT1515CP uses a plug-on design for straightforward installation. The tandem arrangement is specifically intended for load centers with pan rail slots, allowing you to tailor your circuit layout without sacrificing space. All QO breakers are ANSI-certified and UL-listed, reflecting the trusted quality that electricians and builders rely on for residential and light commercial projects.

A notable feature is the Visa-Trip indicator. When the breaker trips, the handle moves to a midpoint between OFF and ON and a bright red marker clearly shows which unit has opened. In large panels with dozens of breakers, this visual cue can simplify troubleshooting and quick re-energizing after service work. This visibility is a hallmark of Square D's commitment to clear, actionable status indicators.

Practical use and installation considerations

Use cases in home or small business environments can include freeing up panel space while maintaining separate control of distinct circuits such as lighting and receptacles, or adding circuits in a compact distribution panel where space is at a premium. While this tandem breaker helps maximize capacity, compatibility with your specific panel is essential. Always follow local electrical codes and panel labeling to ensure safe, compliant operation.

• Ensure your panel supports tandem breakers in the designated slots
• Power down the system and verify zero voltage before handling
• Follow labeling guides and local codes during installation
• Use appropriate wire sizes within 14-8 AWG range
