Description
Built for residential safety, the MPA115AFC delivers 15A of single-pole combination arc-fault protection. It operates on 120V systems to mitigate fire risks by identifying dangerous arcing conditions. This plug-on component mounts into Murray load centers and is replaced by the QA115AFC for newer installations. With a 10kAIC interrupting capacity, the thermal-magnetic unit features a pigtail neutral connection. An integrated LED trip indicator allows users to quickly identify fault events.Specifications

Product FAQs
5 answersWhich load centers are compatible with the MPA115AFC breaker?
This plug-in breaker is specifically designed for use in Murray load centers that accept MP-frame circuit breakers.
How is the neutral connection configured on the MPA115AFC?
The breaker is equipped with a pigtail neutral wire. This wire must be routed and connected directly to the panel neutral bus bar for the arc fault circuitry to function correctly.
What specific faults does this combination AFCI breaker detect?
As a combination arc fault circuit interrupter, it detects both series and parallel arcing conditions to mitigate fire risks, in addition to providing standard thermal-magnetic overload and short-circuit protection.
Can I use a Siemens QA115AFC instead of the MPA115AFC?
Yes. Siemens has phased out the Murray brand and UL listed Siemens QP-frame breakers, such as the QA115AFC, as approved replacements for Murray MP-frame breakers in Murray load centers.
How can I identify why the MPA115AFC tripped?
The breaker includes an integrated LED trip indicator that illuminates to help electricians quickly diagnose whether the trip was caused by an arc fault or a standard overcurrent event.
