Choosing electrical distribution switchgear protection starts with one practical question: how much current does the circuit need to carry, and do you have to switch it remotely? These two breakers answer that question differently. The GE THED134150 is a high-capacity three-phase molded case breaker; the GEYA WiFi MCB is a compact, remotely controlled miniature breaker.
Quick Verdict
For high-current three-phase feeder protection in an industrial or commercial panel, the GE THED134150 is the workhorse. For remote switching on a smaller two-pole branch circuit, the GEYA WiFi MCB is the practical pick. Their price spread is substantial, from USD 45 to USD 460, so the cost difference alone should not drive the decision-current rating and control needs come first.

| Condition | Used tested | New |
| Current rating | 150A | 16-63A |

| Protection type | Molded case circuit breaker | Miniature circuit breaker with short-circuit protection |
Where the GE Wins
The GE takes over when the load gets heavy. Its 150A, 480V, three-pole molded case design is in a different class from a two-pole mini breaker. It is built to protect feeders and motor circuits, and the THED frame is an industrial form factor. If the used tested condition is acceptable for your application, the GE delivers the capacity the GEYA cannot.
Where the GEYA Wins
The GEYA earns its place with control and size. It is a two-pole breaker with Tuya WiFi switch control and an instantaneous break time, so it suits home and garden wiring, commercial electrical circuits, and lighter industrial applications. It is compact, two-pole, and much easier to work into a smart-control setup. For branch circuits where you want the ability to switch remotely, this is the more flexible breaker.
Product Notes
GE THED134150 150A 480V 3P Molded Case Circuit Breaker
Here is the heavy-duty side of the comparison. This is a used, tested molded case circuit breaker from General Electric with a 150A, 480V, three-pole rating in the THED frame. It is aimed at industrial power distribution, commercial switchgear, panelboards, and motor-control work. The thermal-magnetic trip system handles overload and short-circuit protection in one unit. The main limitation is its used surplus history: you are relying on a breaker that has already been in service. Choose it when your panel needs a real three-phase feeder breaker.
GEYA WIFI Tuya Control MCB Circuit Breaker 2P 16-63A & Short Circuit Protection
Here is the remote-control option. This is a new, two-pole miniature circuit breaker with a 16-63A current range and WiFi/Tuya switch control, plus short-circuit protection and an instantaneous break time. It is suited to commercial wiring, home and garden work, electronics, and lighter industrial circuits. The limitation is capacity: at two poles and a 63A ceiling, it cannot perform the role of a 150A three-pole molded case breaker. If the circuit is small enough and remote switching is a priority, this compact MCB is the convenient answer.
Final Choice by Use Case
Choose the GE THED134150 when the circuit is a high-current three-phase feeder and a used MCCB is acceptable. Choose the GEYA WiFi MCB when you need compact branch-circuit protection with remote switch control. Let the load amperage and the need for remote control be the deciding factors, and the right breaker is easy to name.
