Description
Built for three-phase commercial and industrial applications, this miniature circuit breaker delivers reliable thermal-magnetic overcurrent protection. The C-curve trip characteristic is ideal for circuits with medium inrush currents. This unit mounts securely onto standard 35mm DIN rail systems and functions as a direct replacement for the legacy WMZT3C25. With a 14 kAIC interrupt rating at 480Y/277VAC, it utilizes a current-limiting design to minimize let-through energy.Specifications

Product FAQs
7 answersWhat does the "NA" suffix in the FAZ-C25/3-NA part number indicate?
The "NA" suffix indicates that this miniature circuit breaker is UL 489 listed for branch circuit protection in North America, rather than being a UL 1077 supplementary protector.
What does the C trip curve signify on this 25A breaker?
The C curve magnetic trip point activates at 5 to 10 times the rated current. This makes it ideal for applications with medium inrush currents, such as small transformers and pilot devices.
What are the terminal torque specifications for the FAZ-C25/3-NA?
The required tightening torque depends on the wire size: 21 lb-in for 18 to 12 AWG, 25 lb-in for 10 to 8 AWG, and 36 lb-in for 6 AWG conductors.
Can the Eaton FAZ-C25/3-NA be reverse fed?
Yes, this miniature circuit breaker is suitable for reverse feed applications, allowing power to be supplied to either the top or bottom terminals.
Does this Eaton breaker replace older Moeller FAZ series breakers?
Yes, Eaton acquired Moeller, and the current Eaton FAZ-NA series is a direct replacement for legacy Moeller FAZ-NA miniature circuit breakers with matching specifications.
Is this breaker suitable for use as a branch circuit protective device?
Yes, because it is UL 489 listed, it is fully approved for use as a primary branch circuit protective device in industrial control panels and DIN rail systems.
How many wires can be connected to the box lug terminals?
The terminals can accept a single wire ranging from 18 to 6 AWG, or two wires ranging from 18 to 10 AWG.
