The Siemens Q115 is a standard, compact molded case circuit breaker, typically black in color, with a simple on/off switch handle for manual operation and resetting. Its primary function is to safeguard electrical wiring and connected appliances from damage caused by excessive current, which can lead to overheating and potential fire hazards. Its design emphasizes ease of use and reliability for residential applications such as protecting circuits for lighting and general-purpose receptacles.
Features
-
Amperage & Voltage Rating: It has a 15 Amp current rating and is rated for 120V AC operation, suitable for standard household branch circuits.
-
Single Pole Design: This is a single-pole breaker, meaning it is designed to protect one energized conductor (hot wire) in a 120-volt system.
-
Thermal-Magnetic Trip Mechanism: It uses a combination of thermal and magnetic components to provide comprehensive protection: the thermal element handles persistent overloads, while the magnetic element provides instantaneous tripping for sudden short circuits.
-
Interrupting Rating: The breaker features a 10,000 Amperes Interrupting Capacity (AIC), allowing it to safely interrupt high fault currents as required by safety standards.
-
Easy Installation: It has a plug-in (or push-on) mounting style and features the Siemens "Insta-Wire" system, allowing for quick and simple installation into Siemens EQ, PL, and ES series load centers without the need for bolts.
-
Wire Compatibility: The Q115 accepts a range of copper or aluminum wire sizes, typically between 14 to 6 AWG (Cu/Al) depending on the specific application requirements.
