Description
Part of the Siemens Murray line, the MP220AFC is a 20A, two-pole combination arc-fault circuit interrupter. It is designed for residential applications requiring advanced fire protection on 120/240V circuits. This plug-on breaker installs into compatible Murray load centers and is replaced by the Q220AFC. Rated at 10kAIC, it utilizes thermal-magnetic technology to detect parallel and series arcing faults. It includes a pigtail neutral and LED trip indicator.Specifications

Product FAQs
6 answersCan I use the Siemens MP220AFC to replace an older Murray MP220AFC breaker?
Yes. Siemens acquired the Murray brand and phased out the Murray name. The Siemens MP220AFC is the direct, UL-listed replacement for the legacy Murray MP220AFC and is approved for use in Murray load centers.
Is the MP220AFC compatible with standard Siemens load centers?
The MP220AFC is specifically designed and UL-listed for use in Murray load centers. For standard Siemens EQ, Ultimate, or ES series panels, you typically need a Q-series breaker, such as the Q220AFC, rather than the MP series.
Does the MP220AFC require a plug-on neutral load center?
No. The MP220AFC features a pigtail neutral connection, meaning it wires directly to the neutral bus bar. It does not require a specialized plug-on neutral panel for installation.
How should I prepare the wiring for the MP220AFC lugs?
Ensure you are using appropriately sized conductors, which are 14 to 8 AWG for copper or 12 to 8 AWG for aluminum. Strip the insulation according to the manufacturer strip gauge and torque the lug screws to the specifications printed on the breaker to prevent overheating.
What type of arc fault protection does the MP220AFC provide?
As a combination type AFCI, it detects both series and parallel arcing faults to help mitigate electrical fire hazards in residential wiring. It actively monitors the circuit for dangerous arcing conditions that standard thermal-magnetic breakers cannot detect.
Is the MP220AFC suitable for systems with high available fault current?
The breaker provides a standard 10kAIC rating at 120/240VAC, but it is also fully rated for 22kAIC at 240V. This makes it suitable for residential or light commercial applications where the utility transformer delivers up to 22,000 amps of short-circuit current at 240V.
