While Zinsco is an long gone company and not a functioning factory and no longer in production, we still provide a wide selection of Zinsco circuit breakers to meet the community replacement needs. Thanks to Zinsco’s market dominance years ago, there are still a lot of Zinsco breaker boxes and circuit breakers out there, and we want to make sure that our customers have access to high-quality, refurbished and reconditioned breakers that are safe to use. We inspect each breaker before we allow it to be sold, and each one comes with a one-year warranty. At Breaker Outlet, your satisfaction is always our top priority. Order with confidence today.
