Eaton NZMB1-A63 NZM molded case circuit breaker - 25 kAIC

Thermal-magnetic trip (T268) provides fast, coordinated protection for three-phase feeders, reducing the risk of collateral damage in motors and drives. This improves uptime and ensures selective tripping in dense panel racks. Applications include machine centers, assembly lines, and distribution boards where precise protection matters. The 63 A nominal rating with a 50-63 A setting range gives engineers precise overcurrent protection without oversizing, enabling better coordination with upstream protection schemes. The setting range supports scalable protection as loads vary with production demands. The 25 kAIC short-circuit capacity enables fault currents common in industrial networks to be interrupted safely, protecting equipment and reducing arc-flash exposure during maintenance. This capability is critical for switchgear and feeders in manufacturing facilities. NZM1 frame and three-pole construction ensure balanced protection across all phases, improving fault isolation and simplifying coordination with upstream devices. Front-frame clamp connection simplifies panel mounting and reduces installation time. The rocker lever accessory provides ergonomic operation, enabling quick manual testing and reset without compromising enclosure integrity. The compact dimensions fit standard distribution enclosures and streamline retrofits, while the warranty and compliance notes support long-term planning and service.
