Siemens Q115 Circuit Breaker

Siemens Q115 is a 15-amp, 1-pole, 120/240-volt Type QP plug-on circuit breaker designed to protect a single branch circuit in Siemens QP-series panels and compatible Murray/MP panels. It provides thermal-magnetic overcurrent protection with a 10 kA interrupt rating (AIC) at 40°C and UL 489 listing, making it suitable for residential distribution and light commercial circuits. This standard-trip breaker is a 1P, 15A device within the QP family, intended for 120/240V AC loads such as lighting and receptacles, and it is not an AFCI/GFCI by itself. The Q115 is interchangeable with other QP/MP breakers in the same family, offering a compact, reliable solution for branch-circuit protection in 120/240V systems.
