Class 1 reconditioning can extend the useful life of vintage low voltage power circuit breakers. This unique multi-step process restores the breaker to its original capacity and is covered by a 3-year warranty on workmanship and any parts that were replaced. Original manufacturers standards and tolerances are adhered to in both reconditioning and testing. Trip unit upgrades and Arc-Flash Reduction Maintenance System upgrades are available.
When power circuit breakers have reached their end of life and reconditioning is not a good fit, Eaton’s Low Voltage Air Replacement (LV AR-Series) circuit breakers are a good solution. These replacement breakers are brand new and are designed to be the electrical and mechanical equivalents of the breakers they replace, utilizing a Magnum DS breaker with Digitrip technology in an engineered cassette that interfaces with the existing switchgear. Little or no modifications to the existing cell are required, and renewal parts availability issues are eliminated. Higher short-circuit interrupting ratings are available on many LV-AR models with a magnetic bus bracing analysis.
Eaton offers the Low Voltage Vacuum Starter Replacement (LV VSR-Series) for applications with vintage circuit breakers that start and stop motors repetitively. These hybrid power circuit breaker and vacuum contactor devices replace the existing circuit breaker with minimum cell modifications. Current limiting fuses provide primary fault protection and hundreds of thousands of switching operations are possible, extending the useful life of the switchgear by as much as 20-30 years.
