Eaton Specification Sheet - NZMN1-A63-NA
NZMN1-A63-NA combines a 63 A amperage rating with a precise overload setting, delivering dependable overcurrent protection for demanding industrial circuits. The 50-63 A setting range lets technicians tailor protection to load profiles, reducing nuisance trips while preserving equipment life and operating margins. In distribution panels and control cabinets, this molded case breaker supports predictable startup sequences and consistent fault clearance. Configured on the NZM1 frame as a three-pole device, the NZMN1-A63-NA provides coordinated protection across all three phases, minimizing miscoordination risks in motors and drives. Its T268 trip type combines thermal and magnetic sensing for reliable response to overloads and short circuits, helping plant engineers meet uptime targets. The design also aligns with common IEC/CSA requirements to simplify cross-border installations. Front-frame clamp connections enable fast, clean wiring and straightforward panel assembly, reducing field wiring errors and commissioning time. The option to add a rocker lever enhances manual operation and testing in high-volume maintenance environments. By supporting standard mounting on the NZM1 frame, this breaker integrates smoothly with existing protective assets and spare-parts inventories. With a 690 Vac and 500 Vdc rating, NZMN1-A63-NA supports both AC power distribution and DC bus protection, a common need in modern automation architectures. The 50 kAIC interrupt capacity provides headroom for typical industrial fault currents, increasing system safety margins. UL Listed certification, along with CSA and IEC compatibility, helps ensure regulatory compliance across global facilities. Warranty and service considerations include standard Eaton policy with one year from installation or eighteen months from shipment, supporting maintenance planning and lifecycle decisions. The device’s robust construction and standardized accessories minimize replacement intervals and spare-parts costs. Overall, it delivers reliable protection with predictable maintenance, improving downtime resilience and return-on-investment in critical automation environments.

FAQs
The NZMN1-A63-NA uses a front-frame clamp on the NZM1 frame for fast, secure mounting. Install in a three-pole configuration with correct phase alignment, then tighten mounting screws per the spec. Wire connections should be clean and torque-validated before energizing. This approach minimizes mis-wiring and reduces commissioning time in industrial panels.
This breaker provides a 63 A continuous rating and supports 690 Vac / 500 Vdc, enabling mixed AC-DC protection in modern machines. It offers a 50 kAIC short-circuit interrupt rating, a 50-63 A setting range for overload protection, and a three-pole NZMN1 frame with T268 trip type to ensure selective tripping and system safety.
Yes. With a 500 Vdc rating, it is suitable for DC protection in industrial drives and DC buses alongside 690 Vac AC circuits. It carries UL Listed certification and is designed to meet CSA and IEC compatibility, helping you satisfy regulatory requirements while ensuring dependable fault clearance up to 50 kAIC.
Ideal for manufacturing automation panels, motor control centers, and power distribution boards in process plants. The 63 A rating, 50 kAIC capacity, and front-frame clamp support compact, safe installations in compact spaces, while the option for a rocker lever enhances testing and manual operation in high-demand environments.
The NZMN1-A63-NA contributes to ROI through reduced downtime and consistent protection across critical lines. It carries a standard Eaton warranty (one year from installation or 18 months from shipment) and supports low-maintenance operation with reliable tripping. Spare parts and common wear items (like the rocker lever) are readily available to minimize lifecycle costs.
