FAQs
Install the FAZ-Z8/3 using the standard terminals across all three poles, ensuring equal torque on each terminal to prevent hotspots. Verify the mounting orientation fits within the panel space, align with existing conductor routing, and follow the 3 A current rating to select appropriate conductors and protection settings. This streamlined wiring reduces commissioning time and improves reliability in automation panels.
The FAZ-Z8/3 carries UL 1077, IEC 60947-2, and CSA C22.2 No.235 certifications. These mark compliance for industrial protective devices, ensuring safe operation, electrical interoperability, and regulatory alignment in North American and international markets. For engineers, this simplifies audits, procurement, and installation in regulated environments.
Yes. Its 3 A rating with a very low instantaneous setting provides tighter protection for sensitive automation loads such as PLCs, sensors, and drives. The three-pole design ensures balanced protection across phases, while the 15 kAIC interrupting capacity guards against higher fault currents common in automated systems.
The FAZ-Z8/3 employs a 2-3X /n trip characteristic, which offers a controlled instantaneous response tailored for sensitive loads. This minimizes nuisance trips during transient faults while delivering fast protection during sustained overcurrents. In practice, this translates to improved uptime for control panels and reduced wear on equipment from improper tripping.
With a 1 year warranty and standard terminals, the FAZ-Z8/3 reduces maintenance risk and simplifies replacement. Its compact 3x3x3 inch footprint aids panel density, lowering enclosure costs. The combination of tighter protection for delicate loads and proven certifications also lowers downtime costs and supports long-term return on investment in industrial automation projects.
