Eaton / Cutler-Hammer FAZ-C5/2-NA Miniature Circuit Breaker

The NA suffix indicates that this miniature circuit breaker is UL 489 listed for North American branch circuit protection. Standard FAZ breakers without this suffix are typically UL 1077 supplementary protectors.

The C curve magnetic trip point operates between 5 and 10 times the rated current. This makes it suitable for applications with medium inrush currents, such as small transformers, pilot devices, and control circuits.

Yes, this breaker is dual rated for both AC and DC applications. It supports up to 96VDC with an interrupting capacity of 10kA when wired correctly for DC circuits.

The required torque depends on the wire size used. For 18 to 12 AWG wire, torque to 21 lb-in (2.4 Nm). For 10 to 8 AWG, use 25 lb-in (2.8 Nm), and for 6 AWG wire, tighten to 36 lb-in (4.1 Nm).

Yes, Eaton FAZ-NA series breakers feature a trip-free design and can be fed from either the line or load side, making them suitable for reverse feed installations in control panels.
