Siemens QA115AFCP NS Molded Case Circuit Breaker

Siemens QA115AFCP NS is a 15-amp, 120-volt, 1-pole molded‑case circuit breaker in the Siemens Q‑Series lineup. This single‑pole device is a combination arc‑fault circuit interrupter (AFCI), designed to detect and interrupt arcing faults on 120 V circuits, helping reduce fire risk in living spaces. It provides a 10,000‑amp interrupting capacity (AIC) at 120 V and uses a thermal‑magnetic trip mechanism to respond to both overloads and arc faults. As part of the Q‑Series family, the QA115AFCP NS is intended for use in Siemens panels compatible with this line and is commonly installed on branch circuits supplying lighting and receptacles where AFCI protection is mandated. The compact profile and plug‑in form factor of Siemens molded‑case breakers simplify retrofits in existing panels, making it suitable for typical residential installations or small commercial circuits requiring AFCI protection. For accurate replacement, verify the exact catalog number and panel compatibility before installation.
