Description
Part of the FAZ-NA series, this 15-amp, three-pole miniature circuit breaker provides reliable thermal-magnetic protection for commercial and industrial applications. It installs into standard DIN rail systems and serves as an exact functional replacement for the legacy WMZT3C15 model. Rated for 14 kAIC at 480Y/277VAC, the unit features a C-curve trip profile optimized for inductive loads, along with a visual status indicator and a trip-free mechanism to ensure safety during fault conditions.Specifications

Product FAQs
8 answersWhat does the C trip curve indicate on the FAZ-C15/3-NA?
The C curve designates a magnetic trip point of 5 to 10 times the rated current. It is ideal for applications with medium inrush currents, such as small transformers, pilot devices, and control circuits.
Does the FAZ-C15/3-NA meet UL 489 requirements?
Yes, the -NA suffix indicates this breaker is UL 489 listed for branch circuit protection. It can be used in place of UL 1077 supplementary protectors, but UL 1077 devices cannot be used to replace it.
Can the FAZ-C15/3-NA be reverse fed?
Yes, Eaton FAZ-NA series miniature circuit breakers are suitable for reverse feed applications.
What type of DIN rail is required for mounting?
This breaker is designed to mount on a standard 35mm DIN rail.
Can this breaker be used in DC control panels?
Yes, it is rated for DC applications up to 96VDC with a 10kAIC interrupting rating, making it suitable for DC control circuits and power supplies.
Are Eaton and Cutler-Hammer FAZ-C15/3-NA breakers the same?
Yes. Eaton acquired Cutler-Hammer, and the FAZ-NA series is now manufactured under the Eaton name. The FAZ-C15/3-NA catalog number remains identical and fully interchangeable.
How many conductors can be landed in the box lug terminals?
The terminals are rated for either a single conductor from 18 to 6 AWG, or two conductors from 18 to 10 AWG.
Is the FAZ-C15/3-NA a current limiting breaker?
Yes, FAZ-NA devices are current limiting. They are designed to interrupt fault currents within one half cycle, reducing peak let-through current and energy to protect downstream equipment.
