  • Repair circuit breaker | switchgear | fundamentals | Eaton

    A power switchgear conversion is defined as any type of modification or replacement of any device within existing switchgear from the original tested design. Examples include replacing circuit breakers with another type of breaker (e.g. air magnetic to vacuum), upgrading existing bus bracing, and using a power-operated contactor instead of a power circuit breaker for switching duties.
