Choosing a main breaker for an electrical distribution switchgear protection project means balancing ampacity, voltage, and the reality of buying used. A used GE unit with a documented service life can stretch your budget, but only if the details line up. This listing from seller H_b_93wLSIO is a GE 2000 amp 480/277 main circuit breaker in a main breaker panel configuration, and the description gives you a clear picture of its recent service history.
Quick verdict
Priced at USD 26,800.00, this used GE main breaker panel is a serious candidate if you're comfortable with a unit that has a documented service life. The MPN is THPC23620B, the enclosure is aluminum, and it's rated for interior use. It's not a new breaker, but the listed details give you concrete ground to evaluate it against new equivalents.
Who it suits
This switchgear is a natural fit for an indoor service entrance, especially if you're integrating a backup generator. The unit previously served as a generator disconnect, which means it was used in exactly the kind of separation point you might be building. If your project calls for this class of main breaker and you have the ability to address the operational quirks, this is worth a closer look.
What stands out from the listed details
The MPN THPC23620B gives you a reference to cross-check against your existing switchgear. The aluminum material matters if weight or corrosion resistance is a priority. The seller says the unit was installed in 2022 and removed from service in the first week of August 2026, with only a couple of operations. That's a limited amount of duty for a breaker of this size, and the description notes it was used as a generator disconnect.
Meaningful trade-offs
The biggest caveat is the Kirk key: it will need to be swapped out for the disconnect to function. That's an operational task you'll need to plan around before you can use the breaker. Also, the seller states that wire transfers are the only accepted payment method for this item, so your purchase process will need to handle that. Because this is a used unit, you're buying based on the listed condition and description rather than a new-in-box expectation.
Product note
GE 2000 amp 480/277 main circuit breaker HPC Service entrance switchgear RELT
This used GE main breaker panel is listed at USD 26,800.00. A strong reason to choose it is its prior life as a generator disconnect, which makes it straightforward to repurpose for a backup-power feed. The limitation is the Kirk key swap requirement, so factor that into your project timeline.
Bottom line
If you need a heavy-duty service entrance breaker and can work with a used unit, the Kirk key replacement, and a wire-transfer transaction, this GE switchgear is a usable option. The listed MPN, aluminum build, and clear service history give you enough to compare it against new equivalents.
