Siemens Q1515 15 Amp Duplex Circuit Breaker – Space-Saving QT-Type, Half-Width, Black

Overview

The Siemens Q1515 is a space-efficient duplex circuit breaker that packs two 15 Amp, single-pole protections into half the width of a standard unit. Designed for residential panels, it helps you add circuits without crowding the panel interior. With QT-type compatibility, this breaker can support organized, accessible electrical protection for branch circuits in compatible load centers.

Key specifications include a 10,000 AIC interrupt rating, HACR suitability for common household use, and listings from CSA and UL, signaling alignment with recognized safety standards. The device accepts #14-6 AWG copper or aluminum conductors, supporting typical residential wiring practices and helping simplify upgrades or panel expansions. While it offers robust protection, it remains important to verify panel compatibility and follow installation instructions for safe operation.

Why choose a duplex 15 Amp breaker?

• Space-saving design: two single-pole breakers in half the width of a typical unit
• Versatile wiring compatibility: accepts Cu or Al conductors in the 14-6 gauge range
• Clear protection: helps manage overload and short-circuit risk for individual circuits
• Reliable ratings: 10k AIC, HACR rated, CSA certified, and UL Listed

Compatibility and installation notes

The Q1515 is intended for Siemens load centers and meter combinations rated to accept QT breakers. For Canadian applications, use the NC suffix version and refer to the panel diagram to confirm compatibility.

• Manual energize/de-energize control for easy circuit management
• Half-width framing provides room for additional circuits in existing panels
• Suitable for use with standard 1/2-inch panel spaces

Real-world use cases

Ideal when expanding a panel that has limited space, such as upgrading an older home or adding a new branch circuit in a multi-circuit panel. The compact form helps keep the interior tidy and accessible during maintenance, while maintaining clear circuit separation.

As with any electrical upgrade, verify panel acceptance of QT-type breakers and consult the wiring diagram before purchasing to ensure a proper fit for your specific setup.
