Can Molded Case Circuit Breakers be Reconditioned?

May 12th, 2009

The question often comes up. The answer: to a limited extent yes. Since molded case circuit breakers typically cost less than other types of breakers, cost effectiveness of rebuilding molded case breakers is a top concern. On one side of the spectrum older smaller molded case breakers would not be good candidates for a rebuilding procedure. However rebuilding procedures vary with the device at hand. For example, cleaning or replacing breaker current carrying contacts is a relatively cost effective procedure rendering it highly applicable to even some low cost breakers. Before going out the door our used breakers go through a series of checks per our Quality Control Program. As part of that program, breaker contacts would be tested for contact resistance. Based on those test results, the contacts would be cleaned or replaced if necessary. So in the overall view of things, the extent of molded case breaker reconditioning depends on the specific item at hand.
