Eaton FAZ-C13/1-NA-SP – Frequently Asked Questions
1) What amperage and pole combinations does the Eaton FAZ-C breaker come in?
The Eaton FAZ-C miniature circuit breaker is offered from 1 amp up through 15 amps: 1A, 2A, 10A, 13A and 15A, in both single-pole and two-pole builds. Order by the Eaton catalog number, for example FAZ-C2/2-NA for the 2 amp two-pole, FAZ-C13/1-NA-SP for the 13 amp single-pole, and FAZC152NA for the 15 amp. Poles and amperage are fixed per part number, so pick the exact number before you order.
2) What does the C in Eaton FAZ-C mean, and will it hold a motor or transformer inrush?
The C designation is the 5-10X trip curve: the breaker rides through currents up to roughly five times its rating and trips magnetically between five and ten times rating. That headroom is what lets it carry the short inrush of a small transformer, contactor coil circuit or small motor load without nuisance tripping, while still clearing a hard fault. For a purely resistive or electronic load with no inrush, a lower-multiple curve is the better match.
3) I need two-pole protection at 13 amps for a 240V control circuit. Which FAZ-C part number is that?
FAZ-C13/2-NA is the 13 amp two-pole version. If you only need one pole at that rating, the single-pole is FAZ-C13/1-NA-SP. Both carry the same C (5-10X) trip curve, so the only difference is the pole count.
4) Can I use the Eaton FAZ-C for branch circuit protection in a panelboard?
Eaton's FAZ-C is built and listed to UL 489, the standard the description cites for this breaker. Check the amp rating and pole count against what your drawing calls for, and confirm the panel or enclosure you are mounting it in is rated to accept it. It is most commonly specified inside industrial control panels, machine enclosures and OEM equipment assemblies rather than as a residential load center breaker.
5) What kind of wire terminations does the Eaton FAZ-C breaker have?
Standard terminals, meaning conventional box-lug style connections you land the conductor into directly. No special ferrule adapter or plug-in base is part of the breaker, so panel wiring and later maintenance access are straightforward for a panel builder working a row of these.
6) Where can I get the full electrical ratings for the Eaton FAZ-C breaker?
Eaton publishes a spec sheet for the FAZ-C family covering the detailed electrical data, and it is linked on the product record. Pull it when you need the voltage and interrupting figures for a specific amp rating before you submit the panel drawing.
