Description
Product Overview
The Siemens 15A 120V 1 Pole Tandem CAFCI breaker is engineered to deliver high‑performance arc‑fault protection while conserving valuable panel space. Built to UL standards, this tandem breaker occupies the footprint of a single‑pole device yet feeds two independent circuits, making it ideal for modern residential load centers where space is at a premium. The breaker features a robust copper contact system, a 10,000 ampere interrupting capacity (AIC), and a clear LED trip indicator that illuminates instantly when an arc‑fault event is detected, simplifying diagnostics for both professionals and DIY installers. Its load‑lug‑only design eliminates the need for additional wiring accessories, allowing for quick, tool‑free installation. The product dimensions of 3 × 1 × 4.75 inches and a lightweight 6.4 oz profile further enhance its ease of handling during panel upgrades or new construction projects.

Usage
This tandem CAFCI breaker is suited for a wide range of residential applications, including new home construction, remodels, and panel upgrades. It is particularly effective in kitchens, laundry rooms, and home offices where multiple high‑draw appliances share a circuit, as the breaker can protect two separate loads while maintaining a compact panel layout. Electricians and knowledgeable homeowners will appreciate the LED trip indicator, which provides immediate visual feedback during fault conditions, reducing troubleshooting time and minimizing downtime. The breaker’s 10,000 AIC rating ensures it can safely interrupt severe fault currents, protecting downstream wiring and connected devices from damage. Its compatibility with both Murray and legacy Siemens load centers makes it a versatile choice for updating older electrical systems to meet current safety codes.
Why Choose Us
Choosing the Siemens tandem CAFCI breaker means selecting a product backed by decades of industry expertise and rigorous testing. Siemens’ commitment to safety is reflected in the breaker’s autonomous self‑testing capability, which continuously monitors its own performance to detect internal malfunctions before they affect the circuit. The breaker detects all three arc‑fault types—line‑to‑ground, line‑to‑neutral, and series arcs—providing comprehensive protection that exceeds many standard circuit breakers. Additionally, the LED trip indicator and installed‑indicator flags disappear only when the load wires are correctly inserted, ensuring proper installation and reducing the risk of loose connections. With a proven track record of reliability, a 4.6‑star rating from over 70 verified customers, and UL listing, this breaker offers peace of mind for both professionals and homeowners.
