Eaton NZMB1-A50-NA Molded Case Circuit Breaker - 25 kAIC

Feature: NZMB1-A50-NA belongs to the NZM1 frame and is a three-pole distribution circuit protection device. Benefit: Delivers coordinated protection across essential feeders with a compact footprint, reducing panel depth needs and enabling easier space planning in switchgear. Application: Ideal for distribution panels in manufacturing lines and utility rooms where dense, reliable protection is required. Feature: Thermal-magnetic trip type (T268) provides precise overload and short-circuit protection. Benefit: Limits nuisance trips while ensuring fast response to fault conditions, improving uptime and safeguarding equipment. Application: Critical for motors and feeders in heavy industry where load profiles fluctuate. Feature: Setting range 40-50 A and an amperage rating of 50 A. Benefit: Adjustable protection for varying loads, allowing fine-tuning to minimize downtime and false trips. Application: Suitable for feeders feeding motors, transformers, and lighting banks within 40–50 A envelopes. Feature: Front frame clamp and rocker lever access. Benefit: Simplifies installation and testing with secure mounting and intuitive operation, reducing commissioning time. Application: Field serviceability in panel retrofits and new installations. Feature: 25 kAIC short-circuit breaking capacity and 25 kAIC interrupt rating. Benefit: Supports high fault current environments, delivering robust protection for large industrial feeders. Application: Critical in facilities with demanding fault current levels, such as metal processing or batch manufacturing. Feature: 50 A, 480 Vac operation with three poles. Benefit: Reliable, high-performance protection for standard 480 V distribution networks, enabling consistent coordination with upstream devices. Application: Common in commercial and industrial power distribution schemes seeking reliable circuit protection.
