Founded in the early 1930s, by Emile Martin Zinsmeyer and his son Martin Emile Zinsmeyer, Zinsco manufactured circuit breakers and electrical distribution panels. Zinsco no longer makes new electrical equipment and for new products, only aftermarket replacements are commonly available from Connecticut Electric, Challenger, Kearney and Thomas & Betts.

Over the years, LiveWire Supply has been specializing in reconditioned, obsolete and new Zinsco Circuit Breakers such as QCAL100, Q20 and RC3820. Reconditioned products at LiveWire Supply carry the same one-year warranty that comes with all new electrical distribution products. If you don't see a particular model listed, chances are high that we have it in our stock or can procure it for you in no time.

Take a look at our wide selection of Zinsco Circuit Breakers today by using the selection tool at the top of the page. All orders typically ship the same business day that the order was received.
