Choosing an automatic transfer switch for a home standby generator really comes down to one thing: will power switch over to the generator when the utility drops? The Generac RXSW200A3 is a common reference part, and the 200-amp single-phase 120/240-volt version is what many residential installations work with. In this comparison, two entries for that transfer switch both carry the exact same product title, and both are priced at USD 339.00. That changes the normal head-to-head math: instead of choosing between different feature sets, you're choosing between two entries that claim the same part.
Quick Verdict
There is no spec winner here. The two entries share the same product title, condition, fitment designation, part-number references, and warranty statement. Both are shown as automatic transfer switches for the Generac RXSW200A3, and both list the same supporting details. If this transfer switch matches your generator setup, either entry should give you the same product.

Where Each Entry Wins
The table above has no hidden tie-breaker: both entries win on every row that is listed. Neither entry has an advantage over the other on condition, part numbers, type, or generator range. So 'where each wins' is really 'where both win.' That is not a flaw; it makes your decision simpler because you can stop comparing specs and focus on the one thing that matters to you.
Product Notes
Single Phase Generator Automatic Transfer Switch For Generac RXSW200A3 200 Amp - First Entry
The clearest reason to choose this entry is that it spells out the reference numbers you would want to match: RXSW200A3 appears as both the interchange part number and the manufacturer part number. It also lists the transfer switch as a direct replacement, which is useful if you are gathering the exact part designation for your generator project. The stated 2-year warranty adds a concrete protection detail. As for limitations, the stated generator range is 8-24 kW home standby generators, so this entry is aimed at that scope. If you are working within that range and want a clear part reference, this one delivers it.
Single Phase Generator Automatic Transfer Switch For Generac RXSW200A3 200 Amp - Second Entry
The second entry mirrors the first on every major point, including the same direct-replacement designation, the same RXSW200A3 part-number references, and the same warranty statement. That makes it a reasonable pick if you want another presentation of the same information. If you like having a second version of the same specs for cross-reference, this entry is easy to use. The limitation is similar: the stated generator range is 8-24 kW home standby generators, so it is centered on that scope. With both entries matching on the specs that matter, your choice can come down to which one feels easier for you to reference.
Final Choice by Use Case
If you are matching this automatic transfer switch to the RXSW200A3 reference and you want a stated warranty, either entry gives you the same headline product. If you prefer to see the part numbers spelled out, both include them. If you are working within the declared generator range, both entries support the same decision. In this comparison, the honest conclusion is that both entries stand equal.
