FAQs
NGH408036M uses a four-pole frame with metric tapped terminals designed for compatibility with Eaton Series G accessories and standard MCCB lug kits. When selecting panels, verify busbar alignment, lug compatibility, and torque specifications per the official Eaton installation guides to ensure reliable terminations and safe, compliant wiring.
NGH408036M is rated for 800 A current with a four-pole (4P) configuration. This setup supports high-current protection for feeder circuits and motor control applications, enabling selective coordination with upstream protection devices while maintaining stability during fault events.
Yes. With an 800 A rating and Series G architecture, NGH408036M is well-suited for motor protection in demanding machine-control environments like conveyors and processing lines. Ensure proper coordination with upstream devices, confirm short-circuit withstand rating, and follow manufacturer guidance for motor protection tasks.
The provided data lists 'Compliances: Contact Manufacturer,' so exact certifications such as CE marking, UL listings, or IP ratings are not specified here. For definitive certification details, consult Eaton's official NGH408036M datasheet or contact Eaton directly to confirm current approvals and compatibility with your regulatory requirements.
Series G MCCBs deliver robust protection with reliable magnetic/thermal tripping, straightforward field wiring via metric tapped terminals, and compatibility with a wide range of Series G accessories. These attributes translate to reduced downtime, easier maintenance, and improved lifecycle value, especially in high-demand industrial environments where uptime directly affects productivity.
