Siemens Q115DF 15A 1P 120V Circuit Breaker, AFCI, GFCI, Dual-Function, Plug-On | AmpState

Upgrade your electrical panel with the Siemens Q115DF—a compact, single-pole 15-amp 120-volt circuit breaker that adds dual-function AFCI and GFCI protection in a convenient plug-on design. Built for reliability in panelboards, load centers, and electrical distribution, this unit is the smart choice for safer, code-ready circuits.

• Dual-Function Safety: Combines arc-fault (AFCI) protection with ground-fault (GFCI) protection in one device, helping mitigate fire risks from arcing faults and reducing shock hazards from ground faults.
• 1-Pole, 15A, 120V: Ideal for common residential branch circuits and light commercial applications that run on standard 120V with a 15-amp load.
• Plug-On Design: Facilitates quick, straightforward installation into compatible Siemens panelboards and load centers without complicated wiring tweaks.
• Exact Replacement Fit: Siemens part number Q115DF ensures BOM alignment for replacement projects and stocking spare units that match the original specification.
• Versatile Application: Perfect for kitchens, laundry areas, workshops, or any space where enhanced safety protection is desirable on individual circuits.
• Support You Can Rely On: AmpState offers assistance to confirm part compatibility and ensure the breaker fits your panel exactly.

Why it matters: Upgrading to AFCI/GFCI dual-function protection improves safety, helps meet modern electrical codes, and provides dependable trip performance when it counts. The Q115DF is built for durability in everyday use, delivering consistent protection for your critical circuits.

Practical tips for use:

• Verify your panel accepts a 1-pole, 15A, 120V plug-on breaker and that the bus connections are compatible with the Q115DF.
• Power down at the main breaker before installation and follow local electrical codes during replacement or upgrades.
• Maintain BOM alignment by keeping spare Q115DF units on hand for future service needs.
• Pair AFCI and GFCI protection thoughtfully across circuits to minimize nuisance trips while maximizing safety.
