Siemens QA115AFCN 15A 1P 120V Circuit Breaker, AFCI, Plug-On Neutral, Plug-On | AmpState

The Siemens QA115AFCN 15A 1P 120V AFCI Plug-On Neutral circuit breaker is designed for everyday electrical work in panelboards, load centers, and electrical distribution systems. Built for maintenance teams, panel builders, and spare inventories, it delivers reliable arc-fault protection with a direct part-number match that simplifies sourcing and replacements.

• AFCI protection: Detects and interrupt arc faults on the circuit to reduce the risk of electrical fires, helping you meet code requirements and improve long-term safety.
• Plug-On Neutral: The plug-on neutral design streamlines wiring, eliminates separate neutral pigtails, and speeds up installation while minimizing wiring errors.
• 15 A, 1 Pole, 120 V: Ideal for typical residential branch circuits serving outlets and lighting, compatible with standard 120V electrical distribution in many panel setups.
• Direct part-number match: Angled toward professionals who need precise replacements—guaranteed compatibility when matching QA115AFCN with compatible Siemens panelboards and load centers.
• Availability from AmpState: Ready-to-ship and listed under Siemens part number QA115AFCN, making inventory management straightforward for service vans and service technicians.

Who should consider this breaker? Anyone maintaining or building panels who values fast, accurate replacements and code-compliant arc-fault protection. It’s particularly well-suited for maintenance crews stocking spare parts, panel manufacturers prototyping or upgrading distribution, and electricians who require a guaranteed part-number match for quick project turnarounds.

Typical use scenarios include upgrading existing circuits to meet AFCI requirements in living spaces, retrofitting new installations in panelboards and load centers, or keeping a ready supply of exact Siemens components for service calls where time and accuracy matter. Compared to generic AFCI options, the QA115AFCN emphasizes direct compatibility and streamlined installation through its Plug-On Neutral feature, reducing on-site complexity and potential wiring errors.
