Description
Built for demanding commercial environments, this 5-ampere three-pole device offers robust branch circuit protection. The current-limiting design includes a visual status indicator and reverse feed capabilities. Mounting into industrial control panels is streamlined through standard DIN rail compatibility and box lug terminals accepting 18-6 AWG conductors. Delivering a 10kA interrupting capacity at 480Y/277VAC, the C-curve trip profile accommodates standard inductive loads effectively.Specifications

Product FAQs
8 answersWhat does the "C" in FAZ-C5/3-NA indicate?
The "C" designates a C-curve trip characteristic. The magnetic trip point is set between 5 and 10 times the rated current, which is ideal for medium inrush applications such as small transformers, lighting, and control circuits.
Is the Eaton FAZ-C5/3-NA approved for branch circuit protection?
Yes, the "-NA" suffix indicates this breaker is UL 489 listed for feeder and branch circuit protection. It can also be used in applications that only require UL 1077 supplementary protection.
Can the FAZ-C5/3-NA be reverse fed?
Yes, Eaton FAZ-NA series miniature circuit breakers are reverse feed capable. Power can be supplied to either the line or load side terminals without affecting the breaker's performance.
What is the terminal torque specification for the FAZ-C5/3-NA?
The required tightening torque depends on the wire gauge. Eaton specifies 21 lb-in for 18 to 12 AWG, 25 lb-in for 10 to 8 AWG, and 36 lb-in for 6 AWG conductors.
Is this circuit breaker HACR and SWD rated?
Yes, the FAZ-C5/3-NA is HACR rated for use with heating, air conditioning, and refrigeration equipment. Because its 5A rating is under 20A, it is also SWD (switching duty) rated for switching fluorescent lighting loads.
Does the FAZ-C5/3-NA require a specific mounting orientation?
No, this breaker can be mounted in any position on a standard 35mm DIN rail.
Can this breaker be used in DC circuits?
Yes, the FAZ-C5/3-NA is dual-rated for AC and DC applications. It is rated for up to 96 VDC with a 10 kA interrupting capacity.
Is the FAZ-C5/3-NA a current limiting circuit breaker?
Yes, it features a current limiting design that interrupts fault currents within one half cycle. This reduces peak let-through current and energy, providing superior protection for downstream components.
