Eaton NZMB2-A200 Molded Case Circuit Breaker - 25 kAIC
Part Number: NZMB2-A200
Quick Summary
NZMB2-A200 molded case circuit breaker protects distribution panels by interrupting fault currents in industrial electrical systems. When nuisance trips and unclear settings slow projects, reliable coordination and easy maintenance become critical. Warranty is backed by Eaton’s policy (one year from installation or 18 months from shipment), with certifications to be confirmed with the manufacturer. For performance, this unit aligns with distribution circuit protection needs, offering front screw terminals and motor-drive compatibility to streamline installation and service. In practice, engineers leverage the NZM2 frame to coordinate protective devices, minimizing downtime while meeting 600 Vac rating and 200 A load requirements. Its fixed thermal, adjustable magnetic trip (T185) supports precise pick-up settings across 160-200 A and a delayed 1200-2000 A short-circuit range.

200 A rating, 600 Vac, and 25 kAIC short-circuit capacity provide robust protection for feeders and distribution panels, enabling safer startups and reduced arc flash exposure while supporting reliable performance in demanding environments. This translates to improved uptime and compliance with current protection requirements for industrial facilities and assembly lines. The NZM2 frame and front screw connection simplify installation and field service, delivering clearer diagnostics and faster wiring in retrofit projects and new builds alike. The fixed thermal, adjustable magnetic trip (T185) allows precise setting within 160-200 A for overload protection and a 1200-2000 A delayed short-circuit range for selective coordination with upstream devices, delivering predictable protection without nuisance trips. Compatibility with rocker lever and motor-drive accessories extends control options and reduces integration time in motor-based applications. Warranty terms from Eaton reinforce long-term ownership through maintenance windows and service support, supporting measurable ROI through reduced downtime and easy lifecycle management.
