Eaton FAZ-Z63/4 Supplementary Protector - UL 1077

Feature: Four-pole construction with a 63 A rating and 15 kAIC breaking capacity delivers robust multi-phase overload protection for three-phase systems operating in demanding industrial environments with potential high fault currents, ensuring reliable circuit isolation when faults occur. Benefit: This level of fault tolerance minimizes conductor damage and downstream outages during short circuits, improving plant availability, reducing downtime, and cutting emergency service calls. Application: Perfect for panel boards and machinery wiring in manufacturing environments where reliable cross-phase protection matters, including automation racks, conveyor systems, machine control panels, and integrated safety interlocks. Feature: Very low instantaneous setting as noted in catalog notes, enabling finer discrimination between normal and fault currents in critical circuits and long cable runs. Benefit: This precise setting tightens protection for loads more sensitive to overcurrents, reducing nuisance trips and wear on protective devices without compromising safety margins. Application: Servo drives, CNC systems, instrumentation panels, and other automation components where precise protection improves uptime, product quality, and overall line efficiency, even under fluctuating electrical conditions. Feature: Certifications include UL 1077, CSA Std C22.2 No.235, and IEC 60947-2, covering safety, interoperability, and field usage. Benefit: Ensures regulatory compliance, interchangeability with compatible devices, and easier cross-border sourcing, helping engineers simplify procurement decisions and maintain consistent protection across facilities. Application: OEMs and panel builders who require certified protection across regional standards, improving supplier qualification, inventory planning, and maintenance scheduling. Feature: Standard terminals and four-pole design simplify wiring and installation, enabling straightforward wiring harnessing, repeatable terminations, and compatibility with common panel layouts. Benefit: Faster wiring, fewer connection errors, and easier maintenance, lowering installation labor costs, reducing commissioning time, and allowing service teams to swap units with minimal training. Application: Control cabinets and switchgear where quick swapouts and clear wiring layouts matter, supporting modular expansion and scalable architectures. Feature: Compact 3 in x 3 in footprint and 1 lb weight with a one-year warranty, delivering a compact, rugged form factor suitable for crowded enclosures and serviceable for routine replacements. Benefit: Space savings in crowded enclosures, predictable maintenance planning, and lower logistics cost due to standard stock and easy replacements across sites. Application: Tight electrical rooms and OEM assemblies where footprint and warranty coverage matter for lifecycle planning, spare parts strategy, and long-term total cost of ownership.
