Description
Delivering reliable branch circuit protection, this 1A miniature circuit breaker is optimized for industrial environments. Its C-curve trip profile is calibrated for medium inrush currents, making it perfect for coils and small transformers. This two-pole device attaches securely to standard 35mm DIN rail systems and control panels. It functions as a replacement for the legacy WMZT2C01 model. With a 10 kAIC rating at 480Y/277VAC, the breaker features a current-limiting design for safety.Specifications

Product FAQs
9 answersWhat does the -NA suffix in the FAZ-C1/2-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 strictly a UL 1077 supplementary protector.
What applications are best suited for the C-curve trip characteristic on this breaker?
The C-curve magnetic trip point operates at 5 to 10 times the rated current. It is ideal for applications with medium inrush currents, such as small transformers, lighting, pilot devices, and control circuits.
Can the Eaton FAZ-C1/2-NA be reverse fed?
Yes, the FAZ-NA series breakers are suitable for reverse feed applications.
What type of DIN rail is required to mount this circuit breaker?
This breaker mounts securely onto a standard 35mm DIN rail.
Is the FAZ-C1/2-NA a current limiting circuit breaker?
Yes, it features a current limiting design that interrupts fault currents within one half cycle, reducing peak let-through energy to protect downstream circuits.
Does this breaker have a trip-free mechanism?
Yes, it utilizes a trip-free design. The breaker will still trip under fault conditions even if the handle is physically held in the ON position.
Are there field-installable accessories available for the FAZ-NA series?
Yes, the FAZ-NA series supports subsequent mounting of field-installable accessories, including auxiliary switches and shunt trips.
Can I use this UL 489 breaker in an application that only requires a UL 1077 supplementary protector?
Yes, UL 489 listed devices like the FAZ-C1/2-NA can be used in place of UL 1077 supplementary protectors, though UL 1077 devices cannot be used in place of UL 489 breakers.
Is this breaker rated for switching fluorescent lighting loads?
Yes, FAZ-NA breakers rated 20A or less, including this 1A model, are SWD (Switching Duty) rated for switching fluorescent lighting loads.
