Product FAQs
7 answersWhich load centers are compatible with the QA115AFCHH circuit breaker?
This breaker is designed for use in Siemens EQ, EQL, SEQ, EQG, PL, ES, and Ultimate load centers.
Does the QA115AFCHH require a plug-on neutral load center?
No. This breaker features a standard pigtail neutral. The attached coiled white wire connects directly to the panel's neutral bus bar, allowing installation in standard load centers that lack a plug-on neutral design.
What wire sizes are accepted by the lugs on this 15A AFCI breaker?
The terminal lugs accept 14 to 8 AWG copper wire or 12 to 8 AWG aluminum wire.
What type of arc fault protection does the QA115AFCHH provide?
As a combination AFCI, it detects and mitigates both series and parallel arcing faults. This provides more comprehensive protection against electrical fires than older branch-feeder AFCI models.
What does the HH suffix in the QA115AFCHH part number indicate?
The HH suffix designates an extra-high interrupting rating of 65kAIC at 120V. This makes the breaker suitable for applications with high available fault currents, such as installations located very close to a utility transformer.
Can the QA115AFCHH replace a standard 15A Siemens QP breaker?
Yes, it fits the same 1-inch space as a standard Siemens QP breaker. It is commonly used to upgrade standard circuits to meet modern electrical codes requiring arc fault protection, provided there is space to land the pigtail on the neutral bus.
How does the thermal-magnetic trip function work on this AFCI breaker?
The QA115AFCHH combines electronic arc fault detection with traditional thermal-magnetic mechanisms. The thermal element provides a long-time delay for standard overloads, while the magnetic element offers an instantaneous trip response for severe short circuits.
