FAQs

For installation, ensure a 4-pole, 800A device is mounted in a compatible panel with standard MCCB terminations. The unit's 1 inch depth, height, and width support space-constrained enclosures, while ENGLISH tapped terms simplify wiring diagrams. Use appropriate lugs or plug-in adapters as specified by Eaton, and verify panel bus bar compatibility to maintain proper clearance and safe operation.
The NGH408036EC is designed for high-current protection with an 800A rating and LSIG (Long-Time and Short-Time Interrupting Graph) characteristics, delivering predictable fault interruption. Its Series G architecture enables selective coordination when paired with upstream devices, reducing nuisance outages and helping maintain service continuity for critical loads in manufacturing lines or processing plants.
Certification specifics for this exact model are provided by Eaton and can vary by region. Commonly, MCCBs in the Series G family align with CE/UL expectations depending on configuration, and regional approvals govern application in European, North American, or other markets. Always consult the latest Eaton datasheet or contact the manufacturer to confirm current certifications for your installation site.
Yes. Eaton provides application notes on multi-wire terminals for molded case circuit breakers, which support multi-conductor lugs and enhanced wiring flexibility. These resources help optimize lug configurations, improve termination reliability, and simplify future upgrades or coordination with additional MCCB modules.
The NGH408036EC delivers robust overcurrent protection with 100% rated performance and 800A capacity, reducing unplanned downtime and equipment damage. Its compact 1 inch footprint saves enclosure space, while ENGLISH tapped terms and straightforward wiring lower commissioning time. In total, this translates to lower total cost of ownership, faster project timelines, and improved reliability in demanding industrial environments.
