The NZMN2-AF225-NA MCCB leverages a three-pole NZM2 frame to deliver precise protection for distribution circuits up to 225 A, with a 50 kAIC short-circuit breaking capacity that ensures stable operation during fault events; this directly reduces risk of equipment damage and unplanned downtime in harsh industrial environments. The setting range for the overload protector is 225-225 A, with an adjustable delayed range of 1500-2500 A, enabling selective coordination with upstream protection and minimizing unnecessary trips during normal inrush conditions, which translates to higher uptime for manufacturing lines and critical processes. Its front screw connection and compact footprint (front dimensions around 4.134 in x 4.134 in and length 5.866 in) simplify panel retrofits and new installations in space-constrained enclosures, delivering straightforward wiring and faster commissioning for control cabinets. Optional accessories such as rocker lever and motor drive extend operator control and remote protection capabilities, improving ergonomics and enabling easier integration with motor-driven loads without sacrificing protection quality. The included warranty policy (Eaton Selling Policy 25-000) supports maintenance planning and total cost of ownership, while the readily available specification sheet ensures clear, authoritative guidance during project scoping and procurement. Compatibility with standard NZM2-frame systems makes this MCCB a dependable choice for energy-dense automation facilities seeking robust, scalable electrical protection with predictable performance.
