Feature → 1: Amperage rating and fault current handling. The FAZ-Z40/1 provides a 40 A rating with a 15 kAIC fault current capability, enabling reliable protection for standard control circuits without over‑tripping. Business impact: predictable protection margins reduce downtime and spare-part costs. Application: industrial control panels and machine wiring where short-circuit withstand is critical. Feature → 2: Very low instantaneous setting for sensitive loads. The catalog notes describe a very low instantaneous setting to provide tighter protection for loads that are more sensitive to overcurrents. Business impact: fewer nuisance trips preserve process continuity and equipment availability. Application: sensitive loads in packaging, robotics, and automation lines. Feature → 3: Trip type and performance curve. Configured as 2-3X /n, the FAZ-Z40/1 supports selective coordination with downstream devices, improving protection logic and reducing the blast radius of faults. Business impact: improved system selectivity and reduced repair time. Application: multi-device protection schemes in control cabinets. Feature → 4: Physical design for easy installation. With a 1 in length, 1 in height, and 0.75 in width footprint and standard terminals, this unit installs quickly in already-wired spaces and integrates with common DIN rail or panel layouts. Business impact: faster commissioning and lower labor costs. Application: retrofit projects and new panel builds in Wiring & Connectivity. Feature → 5: Certifications and warranty. UL 1077, IEC 60947-2, CSA Std. C22.2 No.235 certifications plus a 1-year warranty provide regulatory assurance and long-term product support. Business impact: reduced compliance risk and predictable maintenance budgeting. Application: North American and international automation environments.
