Description
Part of Eaton's FAZ series, this 20A miniature circuit breaker provides reliable thermal-magnetic protection for commercial and industrial applications. The C-curve trip response is optimized for medium inrush currents, making it ideal for small transformers and pilot devices. It installs into standard DIN rail systems and industrial control panels. Rated for 14 kAIC at 480Y/277VAC, the FAZ-C20/2-NA features a trip-free mechanism, visual status indicator, and reverse feed capability.Specifications

Product FAQs
8 answersWhat does the C-curve trip characteristic mean for this circuit breaker?
The C-curve magnetic trip point activates between 5 and 10 times the 20A rated current. This provides a medium magnetic trip response, allowing the breaker to ride through moderate startup inrush currents without nuisance tripping.
Which load types are best suited for the FAZ-C20/2-NA?
It is designed for applications expecting medium inrush currents. Typical loads include small control transformers, pilot devices, coils, and commercial lighting circuits.
Is the FAZ-NA series approved for branch circuit protection?
Yes. Because the FAZ-NA carries a strict UL 489 listing, it is fully approved for feeder and branch circuit protection in industrial control panels. This differs from standard FAZ breakers that are only UL 1077 recognized for supplementary protection.
Can this miniature circuit breaker be reverse fed?
Yes. The Eaton FAZ-NA series is suitable for reverse feeding. This allows line power to be connected to either the top or bottom terminals, offering greater flexibility for panel wiring and busbar layouts.
Is this breaker rated for switching duty?
Yes. Because the current rating is 20 amps or under, this specific model carries an SWD (Switching Duty) designation, meaning it is certified for regularly switching fluorescent lighting loads.
Will the breaker still operate if the toggle handle is locked or held in the ON position?
Yes. The device utilizes a trip-free design. The internal mechanism will successfully interrupt a fault or overload even if the external handle is forcibly held or locked ON.
How can a panel builder quickly verify the internal contact status?
The breaker features a color-coded contact position indicator on the front face. It displays red when the contacts are closed and the circuit is live, and green when the contacts are safely open.
Are the terminal screws captive on this FAZ breaker?
Yes, the box lug terminals feature captive screws. This prevents the hardware from backing out completely and being lost inside the industrial control panel during installation or maintenance.
