When you're choosing between two molded case circuit breakers for electrical distribution switchgear protection, the real question isn't brand loyalty-it's how much current your panel needs and how much you want to pay. The GE THED134150 and the ABB SACE S3 AG03018959 sit at opposite ends of that decision. The GE is the more powerful option, while the ABB is the more affordable one. Both are breakers with their own strengths. The decision comes down to matching the breaker to the circuit it protects, not just comparing price tags. Here's how to decide.
Quick Verdict
If your installation needs to handle heavier loads, the GE is worth the extra money. If your feed is a typical lighter branch circuit and budget is the priority, the ABB gets the job done with far less spending. The right choice usually depends on your existing panel's rating. That rating tells you whether you're in GE territory or ABB territory.
Comparison
| GE THED134150 | ABB SACE S3 AG03018959 | |
|---|---|---|
| Price | $460.00 | $149.90 |
| Current rating | 150A | 100A |
| Condition | Used | Used |
| Brand | GE (General Electric) | ABB |
| Frame / Series | THED | SACE S3 |
| MPN | THED134150 | AG03018959 |
Understanding the trade-off: The GE's higher current rating explains the gap in price between the two units. If your installation needs a high-current feed, the ABB simply won't do the job. Conversely, if your load is modest, the GE's extra capability is wasted and you'd be overpaying. Matching the breaker to the actual panel is what separates a smart buy from an expensive mistake.

Product Notes
GE THED134150 150A 480V 3P Molded Case Circuit Breaker
This GE breaker is built for heavier duty. It's a three-pole molded case unit in the THED series with support for higher voltage. It's described as a surplus item removed from an operational industrial environment, and the title says it was tested. The mounting style is bolt-on, which fits many commercial panelboards and switchgear. If you're protecting a feeder that carries a heavy load, this unit gives you the headroom you need without stepping up to a larger frame. It's a robust option for feeders that regularly run near capacity. The main trade-off is the cost: it's the more expensive of the two, so be sure the extra headroom is actually required. For a panel designed around a lighter feed, this breaker is more than you'd need.
ABB SACE S3 AG03018959 100A Circuit Breaker
The ABB takes the cost-conscious route in this pairing. It's a used molded case breaker in the SACE S3 series, and it's described as removed from a working environment and tested for basic functionality. It's a practical choice for replacement duty in a panel where the original breaker reached the end of its life. The actual item is pictured, so you can gauge its cosmetic condition up front. If your branch circuit pulls a modest load, this breaker delivers the protection you need without the extra expense of the larger GE. The limitation is its ceiling: it won't handle the same heavy feed as the GE, so it's best suited to installations that stay within its rating. For a straightforward single circuit, it's a sensible buy.
Final Choice by Use Case
Choose the GE THED134150 when you need a more capable breaker with higher voltage support and you're comfortable with the higher cost. Choose the ABB SACE S3 when your circuit is lighter and cost is the deciding factor. For most standard branch circuits in electrical distribution switchgear protection, the ABB is the economical pick; for bigger industrial or commercial loads, the GE's extra capability earns its cost.
