Eaton Specification Sheet - NZMN2-A100-NA
Selling Policy 25-000 - Distribution and Control Products and Services
Thermal-magnetic trip technology delivers fast, selective protection with predictable fault clearing, reducing nuisance trips and extending asset life in continuous industrial processes. The NZMN2-A100-NA operates on a three-pole NZM2 frame, rated at 100 A with a 690 Vac / 750 Vdc maximum, providing robust protection for three-phase loads in manufacturing and distribution panels. A 50 kAIC interrupt rating ensures reliable fault interruption for moderate-to-large installations, while front-screw terminals streamline wiring, commissioning, and maintenance in tight enclosures. Adjustable protection ranges—80-100 A and 600-1000 A delayed short-circuit release—support precise coordination with upstream devices, minimizing downtime and enabling scalable protection schemes as plant layouts evolve. Optional accessories, such as rocker levers and motor drive enhancements, extend control flexibility without compromising protection performance. Compatibility with Eaton accessories helps simplify replacement and upgrades in existing panels.

FAQs
The NZMN2-A100-NA uses front-screw terminals and a three-pole configuration within the NZM2 frame. Its physical footprint is 4.05 in depth, 7.24 in height, and 4.13 in width, with an approximate weight of 6 lb. Ensure proper mounting clearance and torque per the datasheet, and plan wiring channels to accommodate the 100 A rating and three-phase connections for straightforward replacement in existing panels.
Key specifications include a 100 A amperage rating, 690 Vac / 750 Vdc voltage rating, and a 50 kAIC short-circuit interrupt capacity. The trip type is T268, designed for thermal-magnetic protection. The device is front-connected, three-pole, and supports adjustable settings for overload (80-100 A) and delayed short-circuit releases (600-1000 A), enabling selective coordination in protective schemes.
Yes. The three-pole NZMN2 on the NZM2 frame is well-suited for motor control centers and distribution panels in industrial environments. Its 100 A rating, high interrupt capacity, and front-screw installation streamline MCC integration, while compatible accessories like rocker levers and motor drive options support remote operation and faster commissioning in standard control panels.
The product is UL Listed, validating adherence to recognized electrical safety standards. Eaton provides installation guidance and a one-year warranty under policy 25-000 (or 18 months from shipment). For other regional standards, consult the manufacturer to confirm any additional certifications or compliance notes relevant to your facility.
The unit’s thermal-magnetic protection delivers reliable fault isolation with minimal mechanical wear, helping reduce maintenance costs. Its adjustable settings facilitate ongoing coordination as system loads change, potentially extending service intervals. Replace when the device shows signs of degraded tripping performance, arcing, or after exceeding its recommended service life in your facility’s maintenance plan.
