FAQs

NGH408035MC uses the standard Series G form factor with a 4P configuration and metric tapped terminations. For proper installation, ensure compatible lugs and mounting hardware are used, refer to Eaton's tap rules application notes, and follow the quick selector guides to match the exact panel application. This reduces wiring errors and supports safe, reliable commissioning.
This unit is rated for 800A with a 4-pole configuration (4P). It is described as 100% rated and uses metric tapped terminations. The compact 1 in depth, height, and width and a 1 lb weight support easy integration into space-constrained panels. For detailed limits, always verify the regional approvals in the Series G datasheet.
Yes, as a Series G molded case circuit breaker, NGH408035MC is designed for use in machine control panels and automation applications requiring reliable short-circuit protection and easy integration with motor protection strategies. Consider pairing with Eaton motor operators and selective coordination resources to optimize motor protection and panel performance.
Certification status varies by region. While the data notes general compliances, you should consult the Series G datasheet and local Eaton documentation to confirm SIL, CE, and IP-related approvals for your market. Regional approvals determine eligibility for specific installations in controlled environments and on equipment with stringent reliability requirements.
The 800A, 4P Series G MCCB with metric terminations and a compact footprint reduces installation time and panel footprint, lowering labor and material costs. Its 100% rated performance supports longer service intervals and fewer nuisance trips, contributing to higher line availability and lower total cost of ownership in automated manufacturing environments.
