FAQs
FAZ-Z4/3 is designed for three-pole protection in industrial control panels, safeguarding sensitive loads within automation systems. With a 4 A rating and very low instantaneous setting, it minimizes nuisance trips in machines and packaging lines while complying with UL 1077, CSA, and IEC standards. Standard terminals simplify panel retrofits and spare management, making it a practical choice for modernizing legacy controls.
The FAZ-Z4/3 features a 4 A current rating, 15 kAIC interrupt capacity, three-pole configuration, and 2-3X trip type. It uses standard terminals for easy wiring, and its compact housing measures 3.5 in length, 3 in height, and 2.25 in width with a 1 lb weight. These specs balance protection for sensitive circuits with installation simplicity.
Yes. FAZ-Z4/3 is certified under UL 1077 and CSA Std. C22.2 No.235, and it adheres to IEC 60947-2 requirements. This certification suite ensures regulatory compliance, interoperability with global electrical installations, and reliable performance in industrial environments, making it suitable for multinational manufacturing facilities and contract manufacturers.
Absolutely. The device’s very-low instantaneous setting provides tighter protection for loads prone to overcurrents, reducing nuisance trips without compromising safety. This is especially beneficial for control circuits, sensors, and low-current actuators in automation panels. The three-pole design ensures balanced protection across all phases, improving overall system reliability and uptime.
FAZ-Z4/3 uses standard terminals and a compact footprint (3.5 in x 3 in x 2.25 in, 1 lb), facilitating quick retrofits in existing enclosures. Ensure mounting aligns with panel space for three-pole devices and verify compatibility with nearby protective devices. The 1-year warranty supports service planning, while its 4 A protection suits many auxiliary circuits without overdesigning protection schemes.
