The Eaton WMZ series breaker family has been transitioned to the Eaton FAZ series breaker family. FAZ supplementary protectors are direct replacements for the WMZS series supplementary protectors. They are UL 1077-listed for applications in which branch circuit protection is not required or already is provided. They are thermal-magnetic and protect against short-circuit and overload conditions. The FAZ-NA current-limiting miniature circuit breakers offer protection for branch and control circuits up to 40 Amps and are direct replacements for the WMZT series miniature circuit breakers.
