Zinsco is out of business, but was a major supplier of circuit breakers and breaker boxes. My whole neighborhood was built using them back in the 1950's. New old-stock breakers can still be found, but they are expensive, and frankly are the same breakers with the same quality and shortcomings. I bought the Connecticut breakers (30 amp 2-pole & 40 amp 2-pole, both for 240v) to replace two tired, worn-out Zinsco breakers that were not carrying the loads well anymore. The new breakers arrived very quickly, and although they looked quite different on the exterior from the originals, they fit perfectly and look to be better made. For example, the Zinscos used a mild steel strap wrapped around the switch handles to make both circuits open if just one side tripped. What this allowed in my case was just one breaker side was tripping, but the steel strap did not pull the other side open, leaving one side of the 240v circuit live. In my case that left an electric motor trying to start, but couldn't. This almost burnt the motor out. The new breakers use a metal pin through both switch handles; if one goes they both do. Simple change, big improvement in safety. Now, will the new breakers hold up? We'll see.

It now has been months since I replaced our bad Zinsco breakers with the new ones by Connecticut Electric, and the verdict is in: Flawless fit and performance. Not one problem or safety concern. The problems we had with the circuits opening and shutting off our appliances has been cured. These are high quality replacement breakers for the old Zinsco boxes, and even the price was very good. I recommend these circuit breakers.

What can I say? It works great and allowed me to keep my old panel, but still upgrade the electrical. This is only docked one star because one of the 2-pole breakers on the circuit breaker wouldn't reset when it first arrived, so I ended up doing some resistance testing and found that one side wasn't reset properly. Once I knew that, I then I worked it back and forth pretty hard to finally get it to grip the breaker and trip the one side that wasn't resetting. Since then, no problems - resets fine, went into the panel fine as well.

Product is mostly okay. It was shipped badly, just in an envelope. Pieces (plastic) of the breaker had broken off, and came out of the envelope upon opening. Fortunately, the breaker seems functional, and since I don't want to wait forever again, I will not be returning it. Shipping always seems to be an issue with Amazon.

Needed this ASAP,Had a customer that went from a gas to electric dryer, it didn't work. A previous contractor took out the breaker and wiring leaving a useless outlet. Was a great price in comparison to other options. With Prime next day shipping was able to get it quickly.
