Feature → Business Impact → Application: 200 A amperage rating with 690 Vac / 750 Vdc voltage rating provides robust protection for medium-size motor loads and distribution circuits, reducing nuisance trips and ensuring uptime in manufacturing lines. This translates to lower unplanned downtime and improved process reliability in machine centers and panel assemblies. Feature → Application: Adjustable overload range of 160–200 A enables precise coordination with upstream devices and downstream protections, improving selective clearance and fault isolation in complex electrical rooms. Feature → Application: Adjustable short-circuit release (1200–2000 A delayed) supports tailored protection strategies for high-inertia loads and motor starters, minimizing arc-related risks during faults. Feature → Application: Four-pole front screw connection and NZM2 frame ensure easy retrofits and consistent mounting in existing MCCBs, simplifying field installs and reducing commissioning time. Feature → Application: 150 kAIC short-circuit breaking capacity with 85–150 kAIC interrupt rating delivers high fault withstand in demanding environments, supporting compliance with utility and industrial protection standards. Feature → Application: Optional rocker lever and motor-drive accessories expand control capabilities for motor-driven equipment and automation panels. Feature → Application: Compact dimensions (approximately 5.5 in depth and width) with a 5.17 lb weight enable space-efficient installation in crowded electrical cabinets, reinforcing a lean maintenance footprint.

FAQs
The NZMH2-4-A200 is designed for the NZM2 frame and uses front screw connections, simplifying retrofits into existing panels. Its four-pole construction supports standard motor-control centers, and the adjustable trip ranges align with typical plant protection schemes, reducing rework during installation.
Its 200 A rating, 690 Vac/750 Vdc permit broad motor and distribution use, combined with adjustable overload and short-circuit trip ranges. The four-pole NZM2 design, together with optional motor-drive accessories, enables coordinated protection for motors and drives while supporting compact cabinet layouts.
Overload protection is adjustable from 160 to 200 A, and short-circuit release can be set to 1200–2000 A delayed. This enables selective coordination with upstream breakers and downstream devices, improving fault isolation and reducing the risk of unnecessary trips.
Certifications should be confirmed with the manufacturer for your region. MCCBs like the NZMH2 series are commonly associated with CE markings and regional UL/CSA or other agency approvals, along with typical protection and electrical standards. Always verify current approvals before procurement.
Warranty follows Eaton policy: one year from installation or eighteen months from shipment, whichever occurs first. Regular inspection of the trip unit, tightening of front-screw connections, and validating accessory compatibility (rocker lever, motor drive) can help sustain performance and extend service life.
