Division 03 — Shop Remanufacture

Breaker Rebuild

Full shop remanufacture of circuit breakers — air, vacuum, oil and SF6, across low-, medium- and high-voltage classes. Torn down, reconditioned to OEM spec, tested, and documented. Built on the same machine shop that makes the parts and the same crews that service them in the field.

Our process
Teardown → Evaluate → Recondition → Test → Document → Warrant.

Every breaker is fully disassembled, inspected, and restored — worn parts machined in-house or replaced, surfaces re-plated and repainted, then tested before and after. You get the full test record and a one-year warranty. Returned to like-new, ready for service.

One source
All three —
under one roof.

A parts house can’t test it. A field crew can’t make the missing part. We do all three — machine the component, rebuild the breaker, and put it back in your substation. One source, one point of accountability.
