FAQs
When deploying the FAZ-Z50/2 in a control panel, follow the standard two-pole mounting approach and use the standard terminals to simplify wiring. Verify tray space and routing to avoid heat buildup, and torque terminals per manufacturer guidelines to maintain reliable contact. The compact 1.5 in footprint helps maximize usable panel area, enabling cleaner wire management and easier future expansion.
Key specs include a 50 A amperage rating, two-pole configuration, and a 15 kAIC short‑circuit current rating. These values suit medium‑load automation circuits in control panels and machines, providing reliable overcurrent protection while preserving continuity for non-faulted loads. The UL 1077, CSA, and IEC 60947-2 certifications ensure compliance across regions.
Yes. The catalog notes describe a very low instantaneous setting intended to tighten protection for loads more sensitive to overcurrents. This makes FAZ-Z50/2 well‑suited for servo drives, servo amplifiers, and precision sensors where nuisance trips can impact production throughput. Pairing this device with appropriate wiring and proper panel heat management ensures stable operation.
FAZ-Z50/2 is certified to UL 1077, CSA Std. C22.2 No.235, and IEC 60947-2. These certifications support regulatory compliance for North American and international installations. The multi‑certification profile reduces design wind‑back, accelerates procurement, and simplifies audit trails for safety and quality programs in industrial facilities.
The device’s 50 A rating and tight overcurrent protection help reduce nuisance trips, lowering unplanned downtime and maintenance disruptions. A compact form factor eases installation and future upgrades, while the 1-year warranty and Eaton reliability contribute to lower total cost of ownership by reducing replacement frequency and service interventions in busy automation environments.
