Circuit breakers should only be replaced with new tested and Safety Agency Listed circuit breakers, never used or refurbished ones. From the Manufacturer This 120/240 volt Zinsco 20 amp, double pole, thin series replacement circuit breaker is used in a Zinsco load center. Typical applications, up to 8,800 watts, include electric baseboard heat, fan forced heat and 240 volt air conditioners (up to 23,000 BTU). These are only suggested applications and cannot assure compliance with all local codes. Please check local electrical codes before starting any electrical project. Review: Don't go by the picture! - My niece's home was built with a circuit breaker box built by a long-defunct company called "Zinsco." Actually, my home and my in-laws' home also have Zinsco boxes. This company's equipment is quite ubiquitous in homes built in our area of California in the 1950's and 60's. Recently my niece overloaded one of the circuits in her kitchen by using a combination of appliances that she apparently had never used at the same time before. At first this didn't seem to be a big deal, as I easily determined how she managed to cause the circuit breaker to trip when she called me. She told me she went to her breaker box and had tried to reset the circuit breaker, but still had no power on that side of her kitchen. I talked her through resetting the breaker a second and third time, each time having her be sure to really bring the breaker switch down to the off position has hard and far as she could prior to pushing the switch back to the on position. After the third attempt the circuit that was out then had power once again. Knowing that her house had been built in 1975, and having replaced two other circuit breakers (and a neutral / ground bus bar that was actually broken!) for her, I felt this current breaker situation was in need of attention. I told her to not do anything to cause that breaker to trip again and to not shut it off, and I would order a replacement breaker and install it when it arrived. That brings me to this review: The breakers I've been using as replacements are brand new ones, made by Connecticut Electric for these old Zinsco circuit breaker boxes. It is becoming extremely difficult to find any new-old stock Zinsco brand breakers, and to be perfectly frank I don't think buying and using Zinsco brand breakers (even new-old stock) is a good idea. Since any Zinsco brand breakers were designed and made so long ago, whatever testing they met at the time does not meet the equivalent of what the Connecticut Electric breakers meet today. In fact, if you do a search on Zinsco breaker boxes you will find a number of sources of problems that people have had with them over the years, some of them have been serious. But, in fairness to the design and build quality of these boxes, in the three breaker boxes I have immediate access to, I have seen none of the problems that some Zinsco boxes have experienced. I tend to believe that the majority of the problems noted are probably due to poor or incorrect maintenance and / or repairs. All I've needed to do was replace old and tired circuit breakers when they needed replacement (my nieces' home is 46 y.o., my in-law's home is 54 y.o. and my home is 64 y.o.). There is nothing wrong with this particular new Connecticut Electric breaker, other than it was the wrong one for what we needed in my niece's circuit breaker box. Why? Mostly it's my fault because I trusted the picture on the desertcart web page that I purchased it on, instead of reading the entire description and then double checking on the Connecticut Electric web site. The problem? I needed a replacement "dual, tandem single-pole" circuit breaker with separate throws, and this breaker (UBIZ0220) is a "dual, tandem double-pole" circuit breaker with a "common-throw." Big difference! This breaker could have been used to replace the old tandem breaker, but that would mean that if something caused the breaker to trip on one side of the kitchen then both sides of the kitchen would be shut down. Not a catastrophe, but not what we wanted. The desertcart page selling this breaker has the wrong picture (I went back and checked), showing a separate-throw breaker. I'm keeping it because all of our breaker boxes use these breakers as well as the separate throw ones. I've already ordered, received and installed the new breaker in my niece's breaker box, so she's in good shape now. Just don't rely on the desertcart page pictures (and no, I saw no disclaimer that the picture might not be showing the actual breaker I was buying). As for the Connecticut Electric breakers themselves? They are great, work perfectly, are reasonably priced and are readily available for circuit breaker boxes that were made decades ago! Review: It ties two cicuits together - The toggles are tied together, so if one circuit causes a trip, it is going to cause the other circuit to go off also. The old CB was exactly like this one, only the toggles tripped independently. I need to contact the vendor to find out if the pin that ties the toggle together will cause a problem if the pin is removed. Other than that, it seems to be of high quality. ## Features - Replacement Zinsco circuit breaker manufactured new by Connecticut Electric - For use in Zinsco circuit breaker panels - Intertek ETL Listing to UL Standard 489 for US and Canada-Molded case circuit breakers - 10,000 AIC - 20 Amp - 120/240 VAC 2 Pole breaker in 3/4" body - Plug in type - May also be branded as Sylvania (ie, Sylvania RC 3820) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BPF77K | | Best Sellers Rank | #80,302 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #40 in Magnetic Circuit Breakers | | Brand | Connecticut Electric | | Brand Name | Connecticut Electric | | Circuit Breaker Type | Standard | | Current Rating | 20 Amps | | Customer Reviews | 4.5 out of 5 stars 684 Reviews | | Global Trade Identification Number | 00094925030334 | | Included Components | Breaker | | Item Type Name | Circuit Breaker | | Item Weight | 0.4 Pounds | | Manufacturer | Connecticut Electric | | Model | UBIZ0220 | | Mounting Type | Plug-In Mount | | Number Of Poles | 2 | | Number of Poles | 2 | | Part Number | UBIZ0220 | | UPC | 094925030334 | | Unit Count | 1.0 Count | | Voltage | 120 | | Warranty Description | 10 Years | ## Product Details - **Brand:** Connecticut Electric - **Current Rating:** 20 Amps - **Circuit Breaker Type:** Standard - **Mounting Type:** Plug-In Mount - **Number Of Poles:** 2 ## Images ![Connecticut Electric UBIZ0220-New Zinsco RC3820 Replacement Two Pole 20 Amp Thin Series Circuit Breaker - Image 1](https://m.media-amazon.com/images/I/71lErVQwk6L.jpg) ![Connecticut Electric UBIZ0220-New Zinsco RC3820 Replacement Two Pole 20 Amp Thin Series Circuit Breaker - Image 2](https://m.media-amazon.com/images/I/71LkSr1rVfL.jpg) ![Connecticut Electric UBIZ0220-New Zinsco RC3820 Replacement Two Pole 20 Amp Thin Series Circuit Breaker - Image 3](https://m.media-amazon.com/images/I/61OyP5lSODL.jpg) ![Connecticut Electric UBIZ0220-New Zinsco RC3820 Replacement Two Pole 20 Amp Thin Series Circuit Breaker - Image 4](https://m.media-amazon.com/images/I/71eoY3azvpL.jpg) ![Connecticut Electric UBIZ0220-New Zinsco RC3820 Replacement Two Pole 20 Amp Thin Series Circuit Breaker - Image 5](https://m.media-amazon.com/images/I/81pbzl+GiQL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Don't go by the picture! *by B***N on May 10, 2021* My niece's home was built with a circuit breaker box built by a long-defunct company called "Zinsco."

The old CB was exactly like this one, only the toggles tripped independently. I need to contact the vendor to find out if the pin that ties the toggle together will cause a problem if the pin is removed. Other than that, it seems to be of high quality. ### ⭐⭐⭐⭐⭐ Exact fit, good price. *by T***K on April 21, 2025* Although this breaker is considered obsolete by most, I did not want to replace my entire breaker panel at this time. I purchased this and it was an exact fit and high quality. Installed easily. It's working exactly as it should. ## Frequently Bought Together - Connecticut Electric UBIZ0220-New Zinsco RC3820 Replacement Two Pole 20 Amp Thin Series Circuit Breaker - Connecticut Electric UBIZ0230 Newly Manufactured Zinsco RC3830 Replacement Two Pole 30 Amp Thin Series Circuit Breaker,240 Volts, Gray - UBIZ20-New Zinsco Q20 Replacement.
