The Siemens Q1515 is a black, low-voltage miniature circuit breaker with a toggle-style actuator. Its primary function is to optimize the use of space in an electrical panel by effectively doubling the number of circuits available. Each of the two 15-amp circuits operates independently, providing overload and short-circuit protection for standard 120V branch circuits, such as those used for general lighting or receptacles in residential environments. The Q1515 is an efficient and cost-effective solution when a panel is full but additional low-demand circuits are needed.
Features
-
Tandem Design: Combines two separate 15-amp, single-pole breakers into one compact unit that occupies a single 1-inch panel space.
-
Amperage & Voltage Rating: Provides two 15-amp circuits and is rated for 120V AC applications on each pole, or 120/240V AC for the unit.
-
Thermal-Magnetic Protection: Features a reliable thermal-magnetic trip mechanism for dual protection against both overloads (thermal) and short circuits (magnetic).
-
Interrupting Rating: Has a robust 10,000 Amperes Interrupting Capacity (AIC), meeting standard safety requirements.
-
Easy Installation: Utilizes a plug-in mounting style and "Insta-Wire" feature for quick and secure installation in compatible Siemens EQ, PL, and ES series load centers.
-
Compatibility: Intended for use only in Siemens panels and meter combinations that explicitly permit Type QT (Tandem) breakers, as indicated by the panel's wiring diagram.
- Wire Compatibility: The lugs are designed to accept a range of copper or aluminum wire sizes, typically from 14 AWG to 6 AWG.
