With a 200 A amperage rating and an adjustable trip range of 160–200 A, NZMH2-A200 allows precise protection to match load profiles. This minimizes nuisance trips and improves panel reliability in motors and feeders. The short-circuit breaking capacity of 150 kAIC delivers robust fault tolerance for demanding industrial networks, protecting transformers, motors and distribution panels during high-energy faults. The 690 Vac / 750 Vdc voltage rating supports versatile use across heavy-duty industrial power systems, while front screw connections simplify wiring during panel assembly. The three-pole NZMH2 frame NZM2 provides standard distribution protection with consistent phasing, and the rocker lever plus motor-drive option offer ergonomic operation and flexible control integration. The setting range for overload protection (160–200 A) and the delayed short-circuit range (1200–2000 A) give engineers room to optimize coordination while maintaining compact deployment.

FAQs
NZMH2-A200 uses a front screw connection and a three-pole NZM2 frame, simplifying panel installation and wiring layout. Ensure adequate clearance for thermal dissipation and secure mounting to minimize vibration. The unit supports motor-control center configurations and is compatible with optional accessories like a rocker lever and motor-drive option to fit various control schemes.
The device features an adjustable thermal and magnetic trip, with an overload protection range of 160–200 A and a delayed short-circuit range of 1200–2000 A. This combination enables precise coordination with load profiles and downstream protection devices, reducing nuisance trips while maintaining fast response to actual faults in motor feeders and distribution panels.
Yes. The NZMH2-A200 is rated for 690 Vac operation, making it appropriate for demanding industrial power systems. Its 200 A rating and 150 kAIC short-circuit capacity provide reliable protection for feeders, MCCs, and motors running on high-voltage distributions typical in manufacturing, processing, and infrastructure environments.
Certification status for NZMH2-A200 is region-specific and can vary by market. Typical listings may include UL, CE, and IEC standards for MCCBs; however, always verify current certifications with Eaton or your regional distributor to ensure compliance for your installation and regulatory requirements.
Consider rocker lever and motor-drive accessories for easier operation and extended control options. The front screw connection simplifies wiring, and the three-pole NZMH2 with NZM2 frame aligns with standard distribution protection needs. For commissioning, verify mounting, wiring clearances, and any regional labeling requirements that may apply to your panel assembly.
