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 Zinsco 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.

This is a fine replacement for the obsolete and no-longer-made Sylvania and Zinsco breakers.. Our local Home Depot charges $77 + tax for one of these.

This fit my Zinsco entry box without a problem. Took about 10 minutes to take out the old circuit breaker and install this. The shape of this breaker is slightly different than the old breaker I had to replace. The plastic housing on the clip (left in this photo) is raised whereas the old breaker had a slant to the plastic housing. This did not cause any problem other than the faceplate of the entry box was more difficult to place since the additional plastic on the housing prevented the face plate from being flush with the box until I screwed in the 4 bolts holding the face plate to the entry box.
It also seems to be better built than the original.
I recommend this to anyone with the ZInsco entry box.

Anyone with a home built in the 60's knows how expensive these Zinsco breakers are, if you can find them, in the box stores. I've bought several, original, refurbished breakers for my home and they work fine but they're really expensive too. These breakers are exactly like the original and the price no longer makes me want to rip my breaker box off the wall and replace it with a newer one!

The item was received defective with one of the switches stuck in the middle between the on-off positions (see photo). It does not seem that the item was damaged during shipping since there were no cosmetic marks, however, it is more likely that the item was already defective when shipped. I've returned the item to Amazon.

I was replacing an old circut breaker and this one looked the same size, configuration, etc. but fitting it in took some force. Bottom line is it is in and it works!
