Providing essential parallel arc detection, this 15A branch/feeder interrupter meets earlier NEC requirements for bedroom circuits. The unit utilizes a traditional pigtail neutral wire for connection to the panel's neutral bar. It mounts into Siemens EQ, PL, ES, and Ultimate load centers, serving as an exact replacement for older installations. Visual trip indicators assist electricians in diagnosing faults quickly, while the SWD rating allows it to switch fluorescent lighting loads.
Is the QA115AF a direct replacement for the older Q115AF breaker?
Yes. The Siemens QA115AF is the direct replacement for the obsolete Q115AF. Both models provide branch and feeder arc fault protection.
How is the neutral wire connected on the QA115AF?
This breaker features a standard pigtail neutral. The coiled white pigtail wire must be connected directly to the neutral bus bar in your panel. The load power and load neutral wires terminate directly on the breaker lugs.
Can I use the QA115AF in a plug-on neutral load center?
Yes, but you must still connect the breaker's pigtail wire to the neutral bus bar. If you prefer a breaker that connects directly to a plug-on neutral bar without a pigtail, you will need a plug-on neutral model like the QA115AFCN.
What type of arc fault protection does the QA115AF provide?
The QA115AF is a Branch/Feeder Arc Fault Circuit Interrupter (AFCI). It is designed to detect parallel arcs to meet earlier NEC requirements. If your local code requires a Combination AFCI (CAFCI) that also detects series arcs, you will need the QA115AFC model instead.
Which Siemens load centers accept the QA115AF breaker?
This plug-on breaker is compatible with Siemens EQ, PL, ES, and Ultimate series load centers that accept QP type breakers.
Is the QA115AF rated for HVAC and lighting loads?
Yes. This breaker is both HACR rated for use with heating, air conditioning, and refrigeration equipment, and SWD (Switching Duty) rated for switching 120V fluorescent lighting loads.
