Eaton NZMN2-AF250-BT-NA Molded Case Breaker - 50 kAIC

Thermal-magnetic protection within the NZMN2-AF250-BT-NA delivers precise trip coordination, reducing nuisance trips while guarding against overloads and short circuits. This directly improves system uptime and lowers maintenance costs for critical power feeds in machine rooms and control panels. It’s well suited for distribution circuits in industrial facilities where dependable protection and fast fault clearance are essential. 250 A amperage rating with 690 Vac / 750 Vdc capability supports mixed AC and DC distribution in modern plants. The business impact is broader compatibility across equipment and drives, enabling one device to cover both AC distribution and DC bus protection in mixed systems. Applications include panelboards, machine controllers, and motor drives, where consistent protection reduces design complexity. Front-frame clamp connections simplify installation and improve maintainability by allowing secure, tool-free mounting and easy wire termination at the front. This reduces installation time and fault points during commissioning, cutting total project cost. Applications include new builds and upgrades where fast, reliable wiring is critical. 50 kAIC short-circuit breaking capacity ensures safe interruption of high fault currents without damage to the device or surrounding equipment. The business benefit is greater system resilience and fewer catastrophic failures during faults, reducing downtime and repair costs. Suitable for distribution panels in high-energy environments such as metal fabrication, mining, and heavy manufacturing. Rocker lever and motor-drive options provide flexible operator control and remote integration; this expands compatibility with existing control schemes and reduces retrofit risk. The setting range (250-250A) and delayed short-circuit range (1500-2500A) support tailored protection coordination without extensive rewiring. These features make it easier to scale protection as load and process requirements evolve.
