Eaton Specification Sheet - NZMH2-A40-SVE
The NZMH2-A40-SVE uses a three-pole NZMH2 design within the NZM2 frame to deliver robust, distribution-grade protection in a compact form factor, enabling easier panel layout and space optimization for industrial control cabinets. This feature translates to improved reliability and easier retrofit for existing installations where space is at a premium, supporting scalable protection across machines and drives. The adjustable thermal and magnetic trip capability directly reduces nuisance trips while ensuring coordination with upstream and downstream protections, which translates to improved process uptime and lower maintenance costs in motor drive applications. The short-circuit release can be set to 320-400A delayed, enabling selective coordination in feeders and minimizing collateral outages during faults, a critical advantage in high-demand manufacturing lines and packaging equipment. With a short-circuit breaking capacity of 150 kAIC and an interrupt rating of 85-150 kAIC, the device provides high fault withstand for demanding loads and improves overall plant safety and reliability. Front screw connections simplify wiring and field servicing, reducing install time and risk of connection issues, while the rocker lever offers intuitive operation for technicians during commissioning and routine testing. Compatibility with motor drives and distribution circuits is enhanced by the 40 A rating, 690 Vac / 750 Vdc voltage capability, and IEC/EN 60947-2 compliance, helping customers achieve compliant, efficient protective coordination in new builds or upgrades.

FAQs
For NZMH2-A40-SVE installation, use the front screw terminals and ensure panel cutouts accommodate the 4.05 in depth, 7.24 in height, and 4.13 in width. Torque values should follow Eaton’s installation guidelines, and the unit should be mounted on standard DIN rail or compatible panels as per the NZM2 frame footprint to maintain proper clearance and cooling.
The NZMH2-A40-SVE features adjustable thermal and magnetic trips with a setting range on the OL protection of 32–40 A and a short-circuit release range of 320–400 A (delayed). This enables precise protection coordination with feeders and downstream devices, minimizing nuisance trips while maintaining fast response to faults in motor drives and distribution circuits.
Yes. The device is designed as a three-pole NZMH2 with NZM2 frame compatibility, offering robust motor drive protection. Its adjustable trip characteristics, high short-circuit withstand (150 kAIC), and front-access installation make it a practical choice for machine control panels, conveyors, and process drive systems where reliable protection and serviceability matter.
The NZMH2-A40-SVE is UL Listed and compliant with IEC/EN 60947-2 standards. These certifications ensure safety compliance and international interchangeability for panel builders, equipment manufacturers, and end users seeking established, regulator-aligned protection in electrical distribution and motor-drive applications.
By enabling precise protection settings, reliable fault isolation, and easier installation through front screw connections and a rocker lever, the NZMH2-A40-SVE reduces nuisance trips and simplifies maintenance. The 40 A rating and high fault withstand contribute to longer mean time between failures in critical industrial drives and distribution circuits, lowering total cost of ownership.
