The Siemens Q120 is a 20-amp, single-pole Type QP circuit breaker specifically engineered for high-performance protection in residential and commercial electrical systems. In pool applications, this plug-on breaker is a standard choice for protecting 120V branch circuits such as underwater lighting, small pumps, and heater control panels, offering a 10,000 AIC interrupting rating to safely shut off power during a short circuit or overload. It features the “Insta-Wire” connector system to significantly speed up installation and is fully compatible with Siemens PL, ES, and EQ series load centers. While the standard Q120 provides thermal-magnetic protection, pool owners often upgrade to the QF120A (GFCI version) or Q120DFN (Dual Function AFCI/GFCI) to meet strict National Electrical Code safety requirements for ground-fault protection near water.
