Eaton NZMN4-AE1000-NA is a three-pole molded case circuit breaker built on the NZM4 frame, delivering 1000 A protection for demanding distribution circuits. The 600 Vac rating and 50 kAIC at 400 Vac provide strong short-circuit resilience, reducing equipment damage and downtime when faults occur. The bolt-on terminals and front-screw connection simplify field wiring and retrofit compatibility, enabling quicker installations in panel boards and switchgear assemblies. The T268 trip type offers precise coordination for motor drives and process loads, improving system reliability and uptime in manufacturing and processing facilities. With a 500–1000 A setting range for Ol Protectors and an adjustable short-circuit release up to 2000–12000 A delayed, engineers can tailor protection to load profiles and startup surges. Accessories such as rocker lever and motor drive options extend control and machine uptime. This product supports compliance workflows and procurement efficiency by meeting UL Listed requirements and aligning with Eaton’s distribution circuit protection portfolio, reducing total cost of ownership and maintenance interventions while ensuring safe, code-compliant operation.

FAQs
NZMN4-AE1000-NA uses front screw terminals and a bolt-on connection design, enabling straightforward wiring in switchgear and distribution panels. The three-pole configuration fits NZM4 frames, allowing compact footprint integration and simplified field retrofits without displacement of neighboring devices. This setup reduces installation time and minimizes wiring errors while maintaining robust mechanical integrity.
Key ratings include 1000 A amperage, 600 Vac voltage, and 50 kAIC short-circuit breaking capacity at 400 Vac. These specs enable the device to protect high-current distribution circuits and motor loads, sustain fault currents without sustaining damage, and support selective coordination with downstream protective devices in moderate-to-heavy industrial applications.
Yes. With a 600 Vac rating and 50 kAIC breaking capacity, the NZMN4-AE1000-NA is well-suited for distribution panels handling higher fault currents and for motor drive applications that require reliable interruption and coordination. Its NZM4 frame and three-pole design support clean integration with standard industrial panel architectures.
The NZMN4-AE1000-NA is UL Listed, which confirms compliance with recognized safety standards for electrical protection devices. This certification helps satisfy procurement and installation codes in many regions and supports quality assurance programs in industrial facilities, reducing risk during audits and system commissioning.
Expect reduced downtime due to reliable tripping and straightforward front-access wiring, plus easier field servicing with compatible accessories like rocker levers and motor-drive options. The adjustable protection ranges (500–1000 A Ol Protector and 2000–12000 A delayed short-circuit release) enable precise coordination, improving asset protection and potentially lowering total cost of ownership over the equipment life cycle.
