200 A amperage rating drives precise overload protection for high‑demand motor feeders, reducing nuisance trips and extending equipment life. The NZMB2‑AF200‑NA combines a robust protective curve with reliable trip history, supporting predictable machine behavior in automation panels. Front screw connection simplifies wiring in tight enclosures, cutting installation time and improving termination integrity in rugged environments. The three‑pole design on NZM2 frames enables easy coordination with upstream breakers and downstream devices, reducing fault propagation risk. 25 kAIC interrupt capacity clears fault currents quickly, protecting transformers, motors, and cables from damage, while 440 Vac rating matches standard industrial power supplies. The adjustable OL range (200-200 A) and delayed short‑circuit release (1200-2000 A) give you selective protection and reduced inrush nuisance. Motor‑drive compatibility and optional rocker lever facilitate commissioning and maintenance in production lines, machine tools, and packaging equipment. The compact NZMB2 packaging (5.51 in L x 5.86 in H/W, 5.17 lb) fits compact enclosures without compromising protection. Reliability is enhanced by Eaton’s design philosophy and field‑serviceable components; ensure you verify regional certifications with the manufacturer for your safety and compliance requirements.
