Eaton FAZ-Z4/4 Supplementary Protector - UL 1077
Part Number: FAZ-Z4/4
Quick Summary
The Eaton FAZ-Z4/4 supplementary protector provides precise overcurrent protection for sensitive loads in electrical panels. Panel designers often wrestle with nuisance trips and inadequate protection when space is tight and wiring is dense. UL 1077, CSA, and IEC 60947-2 certifications validate the device for global manufacturing environments, while its Z Curve and very low instantaneous setting tighten protection. The four-pole architecture, standard terminals, and balanced 4 A rating simplify installation and reduce downtime in automation panels. The 15 kAIC withstand capability supports short-circuit resilience, helping OEMs meet performance targets without sacrificing footprint or serviceability.
