Eaton FAZ-Z25/3 supplementary protector - UL 1077
Part Number: FAZ-Z25/3
Quick Summary
Eaton FAZ-Z25/3 supplementary protector protects sensitive loads in control panels from nuisance overloads. Engineers often struggle with trips driven by small overcurrents that halt production. This device delivers a very low instantaneous setting, enabling tighter protection. Certified to IEC 60947-2, CSA Std. C22.2 No.235, and UL 1077, it aligns with modern safety and compliance expectations. In practice, the three-pole design with standard terminals supports quick retrofits and reliable three-phase protection for industrial machinery. With a 1-year warranty and compact 3-in footprint, it simplifies stocking, maintenance intervals, and installation in tight panels. Compliance-ready protection translates to lower audit risk and fewer field failures, supporting uptime and total cost of ownership.
