Eaton / Moeller Series
MCCB, UL/CSA
The Klockner Moeller NZMH9-250 series molded case circuit breakers are built on a 250A frame and offer robust overcurrent protection for heavy-duty commercial and industrial power systems. This series includes a wide range of thermal-magnetic (ZM9A) and electronic (ZM9-OBI) trip units, with adjustable or fixed settings spanning from 63A to 250A nominal and extended trip ranges up to 2400A. Available in standard global, CNA (North America), and NA (U.S.) configurations, NZMH9-250 breakers are UL 489 and CSA C22.2 No. 5.1 certified and rated for voltages up to 690V AC. Electronic models feature adjustable long-time and instantaneous trip for selective coordination, while thermal-magnetic models offer reliable, fixed trip curves. Breakers are supplied with bolt-on line/load terminals; operating handles must be ordered separately. Ideal for use in feeders, main distribution panels, motor circuits, and high-capacity switchgear.
