Decent price. Fixed ongoing issue with original decades old breaker. Not sure how long this one will last.

I had a breaker that kept tripping. Swapped out everything inside, and it would still trip. Even with nothing plugged in. I went with Siemens for their long history of quality products. So far, after a week and half, no trips.

I haven't actually installed this yet, but the panel I "inherited" when I bought this place was a Siemens. Before I decided to keep the box I opened up a breaker and found their internals and actions high quality. I have since reworked the entire electrical system in the house and added at least 10 new circuits (breakers) of various amperages - including 2 other tandems. I find the Siemens breakers very reliable and have never had a failure.
I needed to add a couple more circuits to my electrical panel and this is the closest replacement to the Murray style breakers I already have installed. It fits perfectly except that you must first remove the small metal strip that is inserted above the rear contact. You can do this by carefully using a pick or awl to pry it out. After it is removed, the new breaker will insert completely and be fully connected to the panel buss bar.
When the breaker box is full this option is a inexpensive solution. Good quality Siemens split breaker makes two breakers ( 2 separate lines) out of one breaker spot. Split breakers can only go on bottom 3 spots of each column of breakers. This gives you a max increase of 6 more lines in my box. I’ve only added 2 split breakers so if I need it I have 4 more lines I can still add. Great product
These breakers were just what I needed to create extra space in a Siemens panel. These will only work if your busbar has notches in the center. If your busbar is solid all the way across, you’ll have to use the breakers that are twice the price.
Fit the electricals box exactly. Perfect match for the old one. Old one had only 25 volts at the output terminal. This was due to corrosion of the terminals after more than 30 years. Possibility due to moisture getting into the box.
The screws were so tight it was very difficult to tighten them. I had to buy a square bit to tighten them
The breaker was an exact match for the original one. Be sure you take the old breaker with you, they have a great variety and some look very similar but will not plug in correctly.
