Genuine Zinsco Circuit Breakers - Full 1-year Replacement Warranty
Circuit Breaker Service has been specializing in new, used, reconditioned, refurbished, and obsolete Zinsco Circuit Breakers and other electrical supply products for over 20 years. If you have old or hard-to-find circuit breakers, motor controls, bus plugs, or other electrical distribution products that need replacing give us a call or request a quote. We have new, used and obsolete products coming in all the time.

Due to the nature of the reconditioning process, we don't always get a chance to post all of our inventory in our online catalog - many products are often sold before we get a chance to list them. Just because you don't see it listed doesn't mean we don't have it. We likely have it in stock or can get it for you fast - and all of our reconditioned products carry the same 1-year warranty that come with our new products. We offer price matching on all products - if you find it cheaper elsewhere, call us. We typically ship orders the same business day the order was received, so you get the Zinsco circuit breaker you need fast. contact us - customer service is our #1 priority.
