Feature → Business Impact → Application: Thermal-magnetic trip and three-pole design deliver fast, reliable fault clearance across three-phase systems, reducing downtime and equipment damage in manufacturing lines and process facilities. This translates to improved system availability and safer start-up sequences in motor control centers and distribution panels. Feature → Application: Front frame clamp terminals simplify mounting and service access, enabling faster installation and streamlined maintenance in high-density panel cells and retrofit jobs. Benefit: reduced commissioning time and fewer field wiring errors. Feature → Application: NZMN2 frame with 225 A setting and 50 kAIC interrupt capacity supports common industrial fault levels, ensuring compliance with short-circuit withstand requirements in distribution boards and feeders. Benefit: enhanced protection without oversized hardware costs. Feature → Application: Rocker lever and motor drive compatibility extend operational flexibility for machine builders and HVAC/system integrators, enabling ergonomic control and scalable protection schemes. Benefit: improved operator experience and adaptable protection strategies. Feature → Application: Adjustment range for short-circuit release (1500-2500A delayed) and setting range ol protector (225-225A) provide precise coordination with upstream protections, reducing nuisance trips and enabling selective protection in complex power networks.

FAQs
The NZMN2-AF225-BT-NA uses a front-frame clamp connection and is built on the NZM2 frame, making it compatible with many Eaton and third-party distribution panels. Ensure mechanical fit and busbar spacing match your enclosure; the 225 A rating suits mid-range panel boards and control panels with three-phase power.
Key specs include a 225 A amperage rating, voltage ratings of 690 Vac and 750 Vdc, a trip type of T268, and a short-circuit breaking/interrupt capacity of 50 kAIC. It is a three-pole NZMN2 type device with front-frame clamp terminals and a 5.866 in depth, 4.134 in height and width footprint.
Ideal for distribution circuit protection in industrial panels, motor control centers, and process equipment installations. Its three-pole design supports balanced protection for three-phase systems, while the 50 kAIC rating accommodates high fault current environments commonly found in manufacturing and packaging lines.
Certifications for this model are specified by Eaton and vary by region. To confirm CE, SIL, IP ratings, or other regulatory approvals for your location, contact Eaton directly or consult the Eaton specification sheet referenced for NZMN2-AF225-BT-NA.
With a robust thermal-magnetic trip, front-frame mounting for quick service, and compatible accessories like rocker lever and motor drive, maintenance is faster and more predictable. The 225 A setting and 50 kAIC capacity help minimize unplanned outages, improving uptime and contributing to a favorable total cost of ownership in mid- to high-current distribution applications.
