There is no need to purchase a used circuit breaker and you can feel safe and secure purchasing the New Replacements. Many companies that state "reconditioned" do little more than clean the outside of the Circuit Breaker. To properly recondition the HLB Circuit Breaker, you would need to remove the cover screws just to open the Circuit Breaker. You would need to remove the components, smooth the contacts, lubricate the pivot points and hope it passes test. If it does not Pass test, you would need to alter the internal Thermal Components. Also you will void the UL if you open it up. The HLB Circuit Breaker Replacement comes with JRL's one year warrantee.
