FAQs
CB4033B120480G6 is designed for heavy-duty low-voltage distribution and switchgear, featuring bottom feed, three-pole operation, and fusible protection. It fits standard industrial panels and enables reliable high-current control in manufacturing, processing lines, and utility environments while minimizing space and maintenance overhead.
The charge-before-close mechanism ensures the switch closes only after the arc-extinguishing elements are pre-charged, reducing arcing and contact wear. This improves reliability for frequent switching in 480 V systems and extends service life in demanding industrial processes.
Yes. The CB4033B120480G6 supports NEMA ratings including 1, 3R, 4 and 12, making it suitable for indoor, damp, and somewhat harsh environments. This compatibility helps maintain protection continuity in exposed panels and wash-down areas when paired with appropriate enclosure selection.
The product carries UL Listed certification, validating safety compliance for electrical equipment. Its NEMA compatibility further supports regulatory and installer requirements for protected switchgear assemblies used in industrial facilities.
Eaton offers a documented warranty and spare-part availability, with optional features like Ground Fault Relay and Blown Fuse Detection to simplify diagnostics. This reduces downtime, enables proactive maintenance, and supports longer intervals between component replacements in critical power paths.
