I ordered a new Siemens Main Breaker Panel and that ...
I ordered a new Siemens Main Breaker Panel and that 100A main breaker was dead on arrival. So I ordered this 'Used' breaker and it works perfectly. Flips on/off as it should. I haven't tried to pull > 100A through it, so I haven't tested it to see if it trips as it should.

An Easier Fix
I failed an inspection on an addition because my Siemens load panel had too many circuits for not having a single cut-off point. I was looking at some significant re-wiring for adding a 100 breaker. Then reviewed the box and found that this breaker could be added. It took 5 minutes.

Thank you so very much for the circuit breaker! I received it promptly and since i did not have heat nor power , it saved the day.

This was a replacement I had to purchase because the company didnt honor the manufactures warranty.
This is a replacement main breaker for a load center I purchased. The breaker failed to work so I tried to get a warranty refund. Siemans said I would recieve one after running me around in circles for a week but never mailed me a replacement. I won't purchase Siemens products anymore.
