Choosing electrical distribution switchgear protection can feel like two different shopping problems in one search: you might need a compact DC breaker for a solar array, or you might be planning a 2000 A service entrance. The four units here cover that full span, with listed prices from USD 13.28 to USD 26,800. The real decision isn't simply price; it's matching voltage, poles, and fault-protection type to the circuit.
Quick take:
- Need a 2000 A 480/277 service entrance main? GE 2000 amp 480/277 main circuit breaker HPC Service entrance switchgear RELT, USD 26,800.
- Need 150 A, 480 V, 3-pole AC protection? GE THED134150 150A 480V 3P Molded Case Circuit Breaker Used Tested, USD 460.
- Need a solar PV DC isolator/disconnect? GEYA Solar DC Mini Circuit Breaker 1P MCB 6-125A PV Isolator Disconnect Switch, USD 13.28.
- Need ground fault equipment protection at 120 V, 20 A? QCGFEP1020 Ground Fault Equipment Protection Circuit Breaker, USD 175.

Product notes
GE THED134150 150A 480V 3P Molded Case Circuit Breaker Used Tested
This General Electric THED frame breaker is for AC distribution at 150 A, 480 V, and three poles. The reason to consider it is that combination: a three-pole molded case breaker with enough amperage for a feeder or branch circuit. It is listed as used tested, which is the main limitation; if your project requires new breakers, this one doesn't meet that condition. The U.S. origin and bolt-on mounting style are useful fit details, but the decision comes down to whether a used, tested 150 A unit is acceptable for your panel.
GE 2000 amp 480/277 main circuit breaker HPC Service entrance switchgear RELT
This is a service entrance unit, not a branch breaker. The listing describes a 2000 A, 480/277 V switchgear disconnect, with aluminum construction and part number THPC23620B, offered by merchant H_b_93wLSIO. The reason to choose it is the 2000 A capacity for a main breaker or service entrance role. The limitation is the used condition and the scale: at 2000 A, this unit is well beyond what a small commercial or residential panel needs. It makes sense only when the project genuinely demands high-current switchgear protection.
GEYA Solar DC Mini Circuit Breaker 1P MCB 6-125A PV Isolator Disconnect Switch
For solar PV work, this GEYA breaker is the DC-specific option. It is a single-pole mini circuit breaker described as a PV isolator disconnect switch, with a DC current type and instantaneous break time. The reason to pick it is a compact, new DC isolation point for a solar array. The limitation is that it is a single-pole DC device, not a three-phase AC distribution breaker. It is designed for a PV string application, so the job has to fit that role rather than general panel protection.
QCGFEP1020 Ground Fault Equipment Protection Circuit Breaker
The QCGFEP1020, from Eaton | Cutler-Hammer, provides ground fault equipment protection in a 20 A, single-pole, 120 V feed-through design with 30 mA sensitivity. It is listed as new. The reason to choose it is the ground fault protection function, which is different from a standard thermal-magnetic breaker. The limitation is the 20 A, 120 V envelope: this is not a high-amperage feeder or main breaker. If you need branch-level ground fault equipment protection at 120 V, this fits; if you need 150 A or 2000 A, the GE breakers cover that range.
Final recommendation by use case
- For a 2000 A service entrance project: GE 2000 amp 480/277 main circuit breaker HPC Service entrance switchgear RELT.
- For 150 A, 480 V AC distribution: GE THED134150 150A 480V 3P Molded Case Circuit Breaker Used Tested.
- For solar DC isolation: GEYA Solar DC Mini Circuit Breaker 1P MCB 6-125A PV Isolator Disconnect Switch.
- For 20 A, 120 V ground fault equipment protection: QCGFEP1020 Ground Fault Equipment Protection Circuit Breaker.
Start with the voltage and current your circuit actually needs, then use the listed-price spread to see how the options scale: the solar DC breaker sits at the low end, the 2000 A service entrance unit sits at the top, and the 150 A and 20 A breakers sit between them on price and capacity.
