Eaton FAZ-C5/1-SP – Frequently Asked Questions
1) Can an Eaton FAZ breaker be used as the branch circuit breaker feeding a panel?
No. The FAZ is a supplementary protector, which means it protects components and circuits inside industrial equipment downstream of a listed branch circuit protective device. It does not replace a UL 489 branch circuit breaker for service entrance, feeder, or branch circuit protection. Use it for control circuits, machine control, and OEM panel protection, with a UL 489 breaker or fuse ahead of it.
2) Should I pick the C-curve or the D-curve FAZ breaker for a motor or transformer load?
Go D-curve for loads with high inrush, such as motor branch circuits, transformers, and solenoid banks, because the magnetic trip point sits higher and rides through the starting surge. C-curve suits general control circuits, lighting, and PLC or instrument power where inrush is modest. Both curves are offered across the FAZ range, for example FAZ-C5/1-SP on the C side and FAZ-D10/2-NA on the D side.
3) I am protecting a small three phase motor circuit in a machine panel. Which FAZ do I order?
For a three phase load you need a three pole device, and the FAZ-C16/3 is the three pole option in the range at 16 amperes. If the motor draws a hard starting surge, a D-curve device is the better fit for inrush, so match the pole count and rating you need against the D-curve part numbers. Remember the FAZ is supplementary protection only, so the motor branch circuit still needs its listed branch circuit protective device and overload protection.
4) What amperages and pole counts does the Eaton FAZ supplementary protector come in?
The FAZ range covers 1, 3, 5, 10, 15, and 16 ampere ratings in one, two, and three pole builds. Specific combinations include FAZ-C1/2 (1 A, two pole), FAZ-C5/1-SP (5 A, single pole), FAZ-C16/3 (16 A, three pole), FAZ-D3/1-SP (3 A, single pole), FAZ-D10/2-NA (10 A, two pole), and FAZ-D15/1-NA-SP (15 A, single pole).
5) How do I read an Eaton FAZ catalog number like FAZ-C16/3?
Break it into three parts. The letter after FAZ is the trip curve, C or D. The number after it is the current rating in amperes. The figure after the slash is the pole count. So FAZ-C16/3 is a C-curve, 16 ampere, three pole device, and FAZ-D3/1-SP is a D-curve, 3 ampere, single pole device. Getting all three right matters, because a mismatch on poles or curve will either fail to fit the panel layout or nuisance trip on inrush.
6) Why would an OEM panel builder add a FAZ supplementary protector when the panel already has a main breaker?
The main breaker protects the feeder, not each internal circuit. A supplementary protector like the FAZ lets you segment control power, PLC racks, instrument loops, and individual machine functions so a fault on one circuit drops that circuit and leaves the rest of the panel running, and so you can troubleshoot one branch at a time. The miniature body keeps that segmentation from eating DIN space in a crowded enclosure.
7) What kind of terminals does the Eaton FAZ breaker have for panel wiring?
Standard terminals. That is the straightforward box-lug style connection used for direct wiring into control panels and equipment enclosures, rather than a ring-tongue or quick-connect variant. If your build calls for a specific terminal style other than standard, this version is not it.
