This 0.21-pound Siemens snaps into your panel and lets you skip the pigtail wire — it is the simplest path to arc-fault protection for a 15-amp circuit.

This model delivers combo-type arc fault protection (protection against both series and parallel arcs) in a package that weighs 0.21 pounds — that is 2.4 times lighter than the Square D HOM120PCAFIC at 0.5 pounds. At 15 amps and 240 volts, it handles standard bedroom and lighting circuits. The plug-on neutral design means you skip the pigtail wire entirely, which frees up space in your panel and cuts installation time.

Buyers report it is an “exact fit” for their Siemens panels, and another notes it is “exactly as described.” One person admits he ordered the wrong part by mistake — so double-check your amperage before clicking buy. Unlike the Eaton BRN115AF below, which weighs 6.08 ounces, the Siemens QA115AFCN is barely noticeable once it is clipped in. It is also HACR and SWD rated, meaning it works with heating and air-conditioning equipment, plus switching duty for lighting controls.

LED trip indicators tell you exactly why the power went out — that saves you guessing and calling an electrician.

This 20-amp single-pole combination AFCI breaker is built for Siemens panels and runs on 120 volts — a fit for kitchen, living room, and garage circuits. Its standout feature is the LED trip indicators that flash a pattern to identify the last trip condition: an arc fault, an overload, or a ground fault. It also gives you 1/4-inch more wire bend space than older designs, which makes squeezing wires into a tight panel easier.

One buyer wrote: “My old AFCI breaker kept tripping – This works as advertised.” Another reviewer replaced a 5-year-old Siemens QAF that had started nuisance-tripping and swapped it for this QAF2 version, calling it an “improved version of QAF.” At 0.3 pounds, it is still lighter than both the Square D HOM120PCAFIC (0.5 pounds) and the Eaton BRN115AF (6.08 ounces). The 25 lb./in. torque rating on the lugs means you can tighten the screw without stripping it.

You skip the curly pigtail wire entirely with this Square D — you push the breaker onto the neutral bar and you are done.

This 20-amp combination AFCI breaker from Square D uses a plug-on neutral design — instead of fumbling with a white pigtail wire, the breaker connects directly to the panel’s neutral bus bar with one push. That frees up gutter space and reduces connections. It is compatible exclusively with Homeline series 4 and newer load centers, so verify your panel’s generation before ordering.

Owners mention it fits “perfectly” in their Square D HOM panel. One electrician’s customer shared: “They are larger than a standard breaker and need a little more force to install. But overall, are very easy to install.” Another owner says it is the “best price I could find locally or online.” At 0.5 pounds, it is heavier than the Siemens QA115AFCN (0.21 pounds) but still manageable. The Time-Saver Diagnostics built into Square D’s newer design help identify the trip cause without extra gadgets.

One reviewer says this Square D breaker “gives confidence” — at 20 amps and 4 ounces, at 4 ounces versus the Eaton BRN115AF at 6.08 ounces.

This 20-amp combination AFCI breaker from Square D uses a traditional pigtail neutral wire for Homeline load centers and CSED devices, running at both 120 and 240 VAC. Its closest competitor is the plug-on neutral HOM120PCAFIC above — but this model uses a pigtail, which some electricians prefer for backward compatibility. At 4 ounces, it is lighter than the Eaton BRN115AF (6.08 ounces) and fits the same 1-inch wide pole space.

One buyer who installed this breaker to add arc-fault protection reports it has been “solid” and notes: “I like that it protects against both series and parallel arcs — and the built-in diagnostics make it easy to see what tripped.” Another reviewer, an experienced HVAC technician, says his husband “refuses to use anything but square D.” The 10 kA interrupt rating handles typical residential short-circuit scenarios. The catch: some users report occasional nuisance tripping in kitchen circuits with multi-wire branch setups. Make sure the neutral is properly connected to the breaker, not just the neutral bar, to avoid false trips.

One reviewer says this Eaton 15-amp is “almost 30 dollars less than at any stores” — but at 6.08 ounces, it is the heaviest single-pole AFCI here.

This 15-amp single-pole combination arc fault breaker from Eaton is meant for BR series load centers and runs at 120/240 VAC. At 6.08 ounces, it weighs 6.08 ounces versus the Square D HOM120CAFIC at 4 ounces. Buyers consistently praise its price: one reviewer says it is “almost 30 dollars less than at any stores,” and another calls it “perfict fit.” It is UL listed with a 10 kA interrupt rating, so it meets code requirements for bedroom and living room circuits.

Customers note it is a “great price for a home electric breaker” and that it “works like a champ.” One note from a repeat customer: “sales price appears to often vary by the hour.” The breaker is made in the Dominican Republic and is not smart-home compatible. For a basic, code-compliant AFCI that fits Eaton BR panels, it does exactly what it says. If you are building out an Eaton BR system on a tight budget, this is the value pick.

This breaker shields against both arc faults and ground faults — no extra GFCI outlet needed downstream.

This 20-amp single-pole dual-function breaker from ABB (formerly GE Industrial Solutions) packs both arc fault (AFCI) and ground fault (GFCI) protection into a single unit. At 120 volts, it fits bathroom, kitchen, garage, and outdoor circuits where code often requires both types of protection. The plug-in mount makes installation straightforward for any Q-Line panel.

Shoppers say it is an “exact replacement” that “worked perfectly” and that the price is “reasonable” even for shipping to Hawaii. One reviewer, living rurally, said “couldn’t find one in our neighborhood so I decided to order it. It worked absolutely perfect.” However, one installer noted that the breakers felt “very loose in the panel” without the cover on — something to check during installation, though the cover typically secures everything.

ABB acquired GE’s residential electrical product line in 2018, so this breaker is compatible with GE THQL and ABB Q-Line load centers. If you are wiring a wet area or a circuit that needs both arc and ground fault protection, this combo saves you from installing a separate GFCI outlet downstream.
