Selling Policy 25-000 - Distribution and Control Products and Services
The NZMN4-VEF600-NA uses a three-pole NZM4 frame design to deliver robust protection for high-current loads up to 600 A in 600 Vac networks, reducing fault propagation and downtime in demanding facilities. This translates to improved protection coordination and safer, more reliable motor control in manufacturing lines and process plants. The thermal-magnetic trip type T268 provides fast, precise response to overloads and short circuits, helping you avoid cascading trips and extended outages in critical power paths. With selective protection and dedicated generator protection, circuits stay powered for essential loads while non-critical feeders trip when necessary, improving uptime in data centers, machine rooms, and packaging lines. Bolt-on terminals and front-screw connections simplify field wiring and retrofit projects, enabling quicker installations and easier future upgrades. Rocker lever and motor drive accessories offer ergonomic operation and enhanced control for high-demand environments, reducing maintenance time and human error. UL Listed, IEC Rated, and CSA Certified compliance ensures that your panels meet global standards, while the compact NZM4 frame supports space-efficient panel layouts in control cabinets and distribution boards.
