Feature → Business Impact → Application: Thermal-magnetic trip with T268 characteristics delivers fast, reliable fault clearance, reducing unplanned downtime in high-load applications and improving panel reliability for continuous operation in manufacturing environments. This supports precise protection coordination for complex feeders and motor drives, enabling safer startup sequences in automated lines. Application: machine control panels, process lines, and energy feeds benefit from predictable tripping behavior and scalable protection as plant loads grow. Feature → Business Impact → Application: 400 A rating combined with a 690 V AC rating enables handling of high-current motors and feeders with a compact footprint, improving panel density and reducing wiring complexity in industrial facilities. Application: large-discharge feeders, automation panels, and process control rooms. Feature → Business Impact → Application: Front screw connection and rocker lever streamline installation and serviceability, cutting commissioning time and simplifying field upgrades for OEMs and panel builders. Application: retrofit projects and new builds where fast, tool-light installation matters. Feature → Business Impact → Application: Selective and generator protection class supports safer, more reliable operation in critical systems, minimizing collateral outages and enabling easier maintenance scheduling in data centers, processing plants, and manufacturing lines. Application: mission-critical power distribution and safety-critical panel architectures.

FAQs

NZMH3-VE400-SVE uses front screw terminals on a three-pole layout and ships with a rocker lever as standard. Its design accommodates quick field mounting in control panels, with installer-friendly access for wiring and testing. The accessory options include motor-drive compatibility, enabling rapid integration into existing motor control architectures.
The breaker features a 100 kAIC interrupt rating at 480 VAC and is suitable for 690 VAC applications, with a 400 A amperage rating. This combination supports high-energy motor circuits and feeders while maintaining high protection margins in demanding industrial environments.
Yes. The NZMH3-VE400-SVE is designed for selective and generator protection and is compatible with motor-drive protection schemes. Its 400 A/690 V capabilities, along with the rocker lever and front-screw connection, simplify integration into motor control panels and generator-fed distributions. Optional motor-drive accessories enhance applicability in variable-speed drives.
Compliances are typically provided by the manufacturer and may vary by region. For this Eaton NZMH3 series, confirm the exact regulatory listings (such as CE, UL/CSA, and IEC 60947-2 references) with Eaton or your local distributor to ensure alignment with project specifications and local code requirements.
Engineers gain improved protection coordination, reduced downtime from nuisance trips, and faster fault diagnosis thanks to precise trip curves and high interrupt rating. The front screw terminals and rocker lever reduce installation time, while motor-drive compatibility and selective protection support scalable, future-proof panel designs, delivering lower total cost of ownership over the equipment lifecycle.
