Quick take
Electrical distribution switchgear protection is not a single decision. The four breakers in this comparison cover ground-fault equipment protection, WiFi-controlled miniature circuit breaking, DC solar isolation, and a heavy industrial molded case breaker, with listed prices ranging from $13.28 to $460. The tension is practical: a low-price DC breaker cannot handle 480V three-phase loads, and a 150A MCCB is overkill for a solar disconnect. Decide what you are protecting first: equipment grounding, branch circuits, PV wiring, or three-phase distribution.

Decision matrix
- Need ground fault equipment protection on a 20A, 120V circuit → QCGFEP1020
- Need a 2P MCB with WiFi control and short circuit protection → GEYA WIFI Tuya MCB
- Need a DC solar PV isolator/disconnect switch → GEYA Solar DC Mini Circuit Breaker
- Need a 150A, 480V three-phase molded case breaker → GE THED134150
Product notes
QCGFEP1020 Ground Fault Equipment Protection Circuit Breaker
The QCGFEP1020 stands out because it is the only breaker here built around equipment ground-fault protection. The Eaton | Cutler-Hammer unit is listed at 20 amp, 1 pole, with 30mA sensitivity and feed-thru line/load terminals. If your concern is protecting equipment on a 120V branch, this is the fit. The limitation is that its specialization comes with a higher listed price than the mini breakers in this group, and the 20A, 120V profile does not bring three-phase or DC solar capability.
GEYA WIFI Tuya Control MCB Circuit Breaker 2P 16-63A & Short Circuit Protection
For a branch breaker you can control remotely, the GEYA WIFI Tuya Control MCB pairs a 2-pole miniature circuit breaker with WiFi control and short circuit protection. This makes it the automation-friendly pick in the set: the control style points to switch operation, and the break time is listed as instantaneous. The counterweight is that this is an AC MCB rather than a ground-fault breaker or DC PV isolator, so its role is narrower than the solar-focused GEYA in this lineup.
GEYA Solar DC Mini Circuit Breaker 1P MCB 6-125A PV Isolator Disconnect Switch
The lowest listed price sits with this GEYA Solar DC Mini Circuit Breaker, and the title makes its role obvious: a 1P MCB described as a PV isolator disconnect switch for DC solar work. The application list spans commercial, electrical wiring, home and garden, home appliance, healthcare/safety, and industrial settings, and the wire gauge compatibility is listed as 18-3 AWG. What it does not offer is three-phase molded case protection or WiFi control. If your job is DC solar disconnection, this is the direct match.
GE THED134150 150A 480V 3P Molded Case Circuit Breaker Used Tested
Industrial distribution is the reason to choose the GE THED134150. This three-pole molded case breaker is listed at 150A, 480V AC, with a thermal-magnetic trip system and bolt-on mounting. For panelboards, switchgear, and motor control distribution, it is the only option here that matches a three-phase, high-current profile. The offset is that it is a used surplus unit and its listed price is the highest of the four, so you are paying for industrial capacity rather than new-condition status or smart control.
Final recommendation
Start with the circuit you need to protect. For remote switching, the GEYA WiFi MCB is the direct pick. For PV isolation work, the GEYA Solar DC breaker fits the job at the lower end of the price range. When equipment ground-fault protection is mandatory, the QCGFEP1020 covers that specialist role. When the installation is industrial distribution, the GE THED134150 is the heavy-duty match.
