Eaton FAZ Dual-Rated UL and IEC Circuit Breakers

What “Dual-Rated UL and IEC” Means

UL and IEC set standards for low-voltage protection. By meeting both, the FAZ miniature circuit breakers for control panels save you from region-specific redesigns. You keep one bill of materials for domestic and export builds, while inspectors recognize the same device family worldwide.

Wherever your end users are in the world, Eaton FAZ Series IEC 60947-2 compliant breakers deliver tested performance, thermal-magnetic protection, and documented ratings for quicker acceptance during AHJ (Authority Having Jurisdiction) reviews and CE/CSA (Canadian Standards Association) workflows. AHJ reviews are inspections by the Authority Having Jurisdiction—like an electrical inspector or fire marshal—to verify that installed equipment meets safety codes like the NEC using approved components before being energized.

CE and CSA workflows are certification processes so that electrical products meet regional safety standards—CE for Europe and CSA for Canada—through design reviews, testing, and documentation before products can be sold or installed.

Key Features of Eaton FAZ Dual-Rated Breakers

FAZ breakers cover currents from 0.16 A to 63 A in 1-, 2-, 3-, 4-, 1+N, and 3+N-pole versions. Depending on model, interrupting capacity is 15 kA or 10 kA with DIN-rail quick clip and red/green contact indication for fast status checks.

Choose trip curves Eaton FAZ B C D curve circuit breakers (plus K, Z options) to match loads—lighting and controls to high-inrush motors and transformers—improving coordination and reducing nuisance trips in mixed industrial panels.

Typical Applications and Why They Matter

Use FAZ in OEM machines, process skids, MCC auxiliaries, and export-ready control panels. With Eaton FAZ dual-rated UL and IEC circuit breakers, you streamline inventory and shorten lead times across global projects without sacrificing compliance or serviceability.

For panel shops and switchboard builders, the dual-rated approach is a competitive edge: one unified spec, fewer surprises in testing, and consistent documentation for different markets and customer standards.

How to Select the Right FAZ Model

Match the trip curve to the load: B for lighting/control, C for standard motors, D for high-inrush starts; K and Z address special characteristics. Verify short-circuit ratings against available fault current, and pick poles/voltage for AC or DC as required.

FAZ options span up to 63 A with 15 kA/10 kA IEC capabilities and 10 kA UL categories (model-dependent). Add auxiliaries, shunt trips, and busbar accessories to simplify wiring and diagnostics—keeping builds neat and inspector-friendly.

Case-In-Point / Real-World Scenarios

Building one panel for Europe and another for the U.S.? Standardize on UL 489 and IEC 60947-2 miniature breakers from the FAZ family to avoid redesigns and cross-references. You’ll reuse drawings, BOMs (Bill of Materials) and labels while meeting both rulebooks. Supporting field replacements is easier, too. Eaton FAZ Series IEC 60947-2 compliant breakers are widely stocked; your techs can swap like-for-like devices and keep documentation consistent across sites and geographic regions.

Pro Tips & Best Practices

Don’t default to “C” curve—profile the load and choose B, C, D, K, or Z accordingly.
Confirm interrupting capacity versus available fault current at the installation point.
Leverage accessories (aux contacts, shunt trip, busbars) to speed wiring and diagnostics.
Document both UL and IEC ratings on your panel schedule to streamline inspections.

Summary & Next Steps

When you standardize on Eaton FAZ dual-rated UL and IEC circuit breakers, you simplify compliance, inventory, and service—without compromising protection. One breaker family covers domestic and export builds, keeping projects moving and documentation consistent. Ready to spec your next power panel?

Eaton FAZ Dual-Rated Breakers — References & Resources

What does “dual-rated” mean on FAZ breakers?: It means the same device is evaluated to both UL 489 and IEC 60947-2 standards, so you can use one part family for North American and international builds without redesigns.

Which FAZ trip curves should you choose?: Use B for resistive and lighting loads, C for general motors, and D for high-inrush starts. K and Z address specialized needs; always profile your load before selecting the curve.

What current and interrupting ratings are available?: Depending on model, FAZ covers 0.16–63 A, with interrupting capacities of 15 kA or 10 kA per IEC/EN 60947-2, and 10 kA UL categories for select variants.

Can FAZ breakers be used on DC?: Yes. FAZ-NA-DC models support DC applications with defined voltage and interrupt ratings; verify the pole configuration and nameplate values for your circuit.

Do FAZ breakers mount on standard DIN rail?: Yes. FAZ features a quick-clip DIN-rail mechanism and accessories for auxiliaries, shunt trips, and busbar systems to keep wiring neat and scalable.

Are FAZ breakers suitable as UL 1077 supplementary protectors?: The family includes UL 1077 supplementary protector options; select per application and verify local code and equipment listing requirements.

What accessories should you consider?: Common picks include auxiliary contacts for indication, shunt trips for remote opening, and busbar kits to speed multi-pole wiring. Match accessories to breaker frame and pole count.
