Feature → Business Impact → Application: FAZ-Z3/2 delivers a 3 A current rating with a 15 kAIC interrupt capacity in a two-pole package and a 2-3X/n trip curve. This enables fast, selective tripping to protect sensitive loads while minimizing unnecessary outages in small control networks such as instrumentation cabinets and panel subcircuits. The unit uses standard terminals, simplifying wiring and reducing installation time in crowded panels. The very low instantaneous setting tightens protection for loads like sensors and microcontrollers, reducing wear on downstream devices and extending equipment life. Its compact 1.5 in cube footprint lowers enclosure requirements, enabling higher pack density and easier retrofits in legacy systems. Certifications from IEC, CSA, and UL provide regulatory confidence and facilitate audits in mixed electrical environments. The 1-year warranty offers predictable maintenance planning and ongoing reliability for mission-critical automation.

FAQs
FAZ-Z3/2 uses standard terminals and a two-pole package, designed for straightforward panel mounting. It supports common control circuits in wiring and connectivity assemblies and integrates with Eaton or compatible DIN rail enclosures. The two-pole design simplifies wiring and ensures correct phase protection while maintaining a compact footprint for crowded control panels.
FAZ-Z3/2 provides a 3 A current rating with a 15 kAIC interrupt capacity in a two-pole package and a 2-3X/n trip curve. It uses standard terminals and is designed for UL 1077 industrial miniature circuit breaker protection for auxiliary circuits. This combination ensures fast, selective tripping and reliable interruption of fault currents in small control networks such as instrumentation cabinets and panel subcircuits.
Yes. The FAZ-Z3/2 is certified to UL 1077 and IEC 60947-2 and CSA Std. C22.2 No.235, ensuring compatibility with European and North American panels. This means you can meet regulatory requirements in mixed electrical environments and reduce risk during audits. When integrating, verify terminal ratings are compatible with feed wires and that the two-pole form factor fits your enclosure.
Best suited for control panels, instrumentation cabinets, and small automation loops, the FAZ-Z3/2 provides dependable protection where space is tight. Its 3 A rating and low instantaneous setting help prevent nuisance trips on sensitive sensors and electronics, while the 15 kAIC capacity handles short-circuit energy in rugged environments. The standard terminals and compact 1.5 in cube simplify retrofits and maintenance in legacy systems.
With a 1-year warranty and standard terminals, FAZ-Z3/2 minimizes service interruptions and replacement costs. Its tight instantaneous setting reduces gear wear from nuisance trips, lowering maintenance cycles. The compact footprint speeds installation, reduces enclosure wiring complexity, and lowers panel costs over the life of the equipment. In regulated facilities, its proven certifications support faster approvals and ongoing compliance.
