- 10 kA interrupting rating at 277/480 V AC
- DIN-rail screw-clamp terminals simplify panel wiring
- UL 489 listed for branch-circuit applications
30 A 3-Pole IEC Miniature Circuit Breaker
The Eaton FAZ-C30/3-NA provides 30 A over-current protection across three poles for commercial and industrial panels. It mounts on a standard DIN rail and uses a thermal-magnetic trip mechanism with a C-curve characteristic. The breaker carries a UL 489 listing and is rated for 277/480 V AC and 48/96 V DC systems.
Sustained-load behaviour
Under continuous operation the thermal element responds to prolonged overloads while the magnetic element clears short-circuit faults up to 10 kA at 277/480 V AC. The screw-clamp terminals maintain a secure connection during vibration and thermal cycling. This combination limits nuisance tripping on motor-start inrush while still disconnecting persistent fault currents.
Deciding specification
The critical selection parameter is the 30 A, 3-pole, C-curve rating at 277/480 V AC with a 10 kA interrupting capacity. Installations requiring a different ampere rating, pole count, trip curve or voltage class must choose another device. Buyers needing a single-pole breaker, a higher interrupting rating or a different mounting style cannot use this model.

Questions about this item
How much heat or noise does the FAZ-C30/3-NA produce when running continuously at 30 A?
The thermal-magnetic trip unit operates silently with no moving parts during normal use; heat rise follows the IEC curve at the rated 30 A load.
What existing electrical infrastructure must be in place for this breaker to function?
It mounts on a DIN rail, connects via screw-clamp terminals, and requires a three-phase circuit rated 277/480 V AC or 48/96 V DC with a prospective short-circuit current not exceeding 10 kA.
Will this breaker coordinate with older panels that use a 10 kA interrupt rating at 277/480 V AC?
Yes, its maximum AIR rating is 10 kA at 277/480 V AC, matching panels built to that interrupt level.
