What are the recommended direct replacements for the FAZ-G40-3?
This legacy Klockner Moeller breaker is officially replaced by the Eaton FAZ-K40/3 or FAZ-C40/3 models.
Is the FAZ-G40-3 rated as a UL 489 branch circuit breaker or a UL 1077 supplementary protector?

Does the FAZ-G40-3 support reverse feed wiring?
Yes, this breaker is suitable for reverse feed applications. It also includes a trip-free mechanism and a visual trip indicator to assist with safe operation and troubleshooting.
Are the box lug terminals on the FAZ-G40-3 finger-safe?
Yes, the box lug terminals are designed to be finger-safe, reducing the risk of accidental contact with live electrical parts during maintenance.
