FAQs
NZMN2-AF100-NA is designed for the NZM2 frame and uses front screw termination, making it easy to wire and replace in existing distribution panels. Its compact dimensions (4.05 in depth, 4.13 in width, 7.24 in height) support tight panel layouts, and the three-pole configuration fits standard 3-phase feeders. This combination streamlines retrofits and new builds, reducing installation time and wiring complexity.
The unit provides 100 A at 690 Vac / 750 Vdc with a 50 kAIC short-circuit breaking capacity and a thermal-magnetic trip (T268). This ensures fast fault interruption while maintaining coordination with upstream protections, helping to minimize damage from faults and reduce downtime in power distribution.
Yes, it is suitable for distribution protection in automation panels and can be paired with motor drive accessories. The options for rocker lever and motor drive enhance control and commissioning, while the 100 A rating supports typical motor protection schemes in small to medium automation applications.
NZMN2-AF100-NA is UL Listed, indicating it meets recognized safety standards for electrical protection devices. This certification supports compliance in North American markets and simplifies procurement for regulated projects, providing confidence in safety and performance during audits and inspections.
Eaton products include a warranty per Selling Policy 25-000, typically one year from installation or eighteen months from shipment, whichever occurs first. This provides coverage for manufacturing defects and supports replacement or service planning, contributing to total cost of ownership reductions over the product lifecycle.
