The NZMN1-AF30-NA is a three-pole molded case circuit breaker with a 30 A amperage rating that supports precise load protection for small-to-medium distribution circuits. Feature → Business Impact → Application: Thermal-magnetic trip (T268) delivers fast response to overloads and short circuits, reducing the risk of equipment damage and unplanned downtime; the benefit is increased line reliability for critical machinery and packaging lines. This unit supports a 50 kAIC short-circuit breaking capacity, which translates to higher fault withstand and safer startup sequences for large motor loads in conveyors and presses. The front frame clamp and 3-pole design enable straightforward, secure mounting in standard NZM1 frames, meaning faster panel assembly and easier retrofits in existing electrical cabinets. With 690 Vac and 500 Vdc ratings, this MCCB is well suited for mixed-voltage control panels common in machine automation, while the rocker lever provides intuitive operation during maintenance or fault testing. The NZMN1 frame, combined with a 30-30A setting range, offers precise overload protection and scalable protection strategies for evolving line layouts, minimizing wasted protection capacity and enabling cost-effective protection budgets. Warranty details follow Eaton’s policy, contributing to long-term ownership value and predictable service costs for capital equipment across maintenance cycles.
