Description
Supplying reliable 5mA Class A ground-fault mitigation, this 30-amp two-pole device is perfectly suited for demanding residential loads like spas or outdoor equipment. It mounts into compatible Murray enclosures, utilizing a standard pigtail neutral for the return path. The thermal-magnetic core includes HACR ratings and an internal self-test protocol to verify operational integrity. For future replacements, the Siemens QF230A serves as the manufacturer-designated substitute.Specifications

Product FAQs
8 answersWhat load centers are compatible with the Siemens MP230GFA?
The MP230GFA is designed for use in Murray load centers. While Siemens manufactures this breaker, it is specifically built to fit panels that accept Murray MP frame breakers. Always verify the accepted breaker types on your panel's wiring diagram before installation.
Can I use the MP230GFA in a Square D or GE panel?
No. The MP230GFA is strictly listed for use in compatible Murray load centers. It is not UL listed for use in Square D, GE, Eaton, or other competitor panels. Mixing brands without a specific UL classification violates electrical code and voids the panel listing.
Is the MP230GFA interchangeable with a standard Siemens QPF breaker?
No. The MP230GFA is an MP frame breaker originally designed for Murray panels. Standard Siemens QPF breakers are designed for Siemens EQ load centers. Although Siemens owns the Murray brand, you must use the exact breaker type explicitly listed on your panel's door label to maintain the UL listing.
How does the MP230GFA connect to the neutral bar?
This breaker features a pigtail neutral connection. The coiled white wire must be connected directly to the panel's neutral bus bar to power the internal ground fault circuitry and ensure proper GFCI protection.
Does this breaker require a plug-on neutral panel?
No. The MP230GFA uses a traditional pigtail neutral wire, meaning it can be installed in standard Murray load centers that do not have a plug-on neutral bus design.
What wire sizes are accepted by the lugs on the MP230GFA?
The breaker terminals accept 14-6 AWG copper (Cu) wire or 12-6 AWG aluminum (Al) wire. Ensure proper torque is applied to the lugs during installation to prevent loose connections and overheating.
What is the interrupting rating of the MP230GFA?
It has a standard interrupting rating of 10kA at 120/240VAC, but is rated up to 22kAIC at 240V. This makes it suitable for residential and light commercial applications where the available fault current does not exceed 22,000 amps at 240 volts.
What type of protection does the MP230GFA provide?
This breaker provides thermal-magnetic protection against overloads and short circuits, plus integrated ground fault (GFCI) protection. The LIG trip functions (Long-Time, Instantaneous, Ground Fault) ensure comprehensive safety for wet or damp locations like pools, spas, or outdoor circuits.
