The Siemens Q120 is a 1-pole, 20 Amp, Type QP/MP low voltage miniature molded case circuit breaker specifically designed for use in residential and light commercial single-phase electrical distribution systems. Its primary function is to provide thermal-magnetic protection against damaging overloads and short circuits in branch circuits. The breaker is engineered for rapid installation and secure fit with a plug-in (push-on) mounting style into compatible Siemens load centers, such as the EQ, EQL, SEQ, or EQG series. It occupies only one slot in the panel and is a standard component for protecting typical 120 V circuits like lighting, receptacles, and small appliances.
