Siemens Q120 is a 20-amp, single-pole plug-in circuit breaker for 120-volt residential panels, part of the Siemens QP family. It provides thermal-magnetic protection with a 10 kA interrupting capacity and mounts in Siemens QP-frame load centers for reliable overcurrent protection on typical lighting and receptacle circuits. This 1-pole, 120V device is designed for standard 20A circuits and is used as a replacement for compatible Siemens panels that accept QP breakers.
