With an 80 A amperage rating and a dual voltage capability of 690 Vac or 750 Vdc, the NZMH2-A80 is built for robust distribution circuit protection in modern industrial panels. This meets typical feeder protection needs in manufacturing lines and process equipment, delivering reliable interruption during fault conditions without compromising downstream devices. In practice, this translates to fewer unplanned trips and tighter coordination with other protective devices in the NZM series. The adjustable thermal and magnetic trip enables precise tailoring to motor starting profiles and overload conditions, reducing nuisance trips, improving equipment longevity, and enhancing overall plant uptime. The three-pole design in the NZM2 frame supports balanced three-phase protection, while screw mounting and clear labeling simplify installation and field servicing in busy control rooms. UL Listed certification further supports regulatory compliance and safe integration into industrial protection schemes. Together, these features deliver faster commissioning, easier maintenance, and consistent protection across panels and machinery in manufacturing and process environments.
