Part Number: CB2033B120480GAX
Quick Summary
Eaton CB2033B120480GAX pringle bolted pressure contact switch protects large industrial power feeds in demanding environments. Operators often struggle with nuisance trips and unreliable fault signaling, driving maintenance costs and downtime. UL Listed safety certification with broad NEMA 1, 3R, 4, and 12 compatibility. Designed for low-voltage switchgear and three-pole protection, it helps reduce downtime and support compliant upgrades. In practice, the 2000A rating, 480V system voltage, and 120V control voltage give engineers a scalable, safer solution for large feeders. Bottom feed and fusible protection streamline installation in control panels and switchgear, while optional ground fault relay and auxiliary provisions support fault detection and future expansion.

FAQs
For bottom-feed models, ensure proper orientation within the panel to align with the feed hardware and ensure the ground fault transformer is accessible for maintenance. Verify enclosure compatibility with the mounting footprint and confirm auxiliary contact provisions meet the control-system requirements. Following the Eaton spec sheet helps prevent mis-wiring and ensures safe, reliable operation.
The switch is rated for 2000A with a 480V system voltage and a 120V control circuit, and it employs fusible protection. This combination supports heavy motor feeders and large power distribution schemes while enabling straightforward overcurrent protection coordination. When designing protection schemes, account for the three-pole, three-wire configuration and ensure compatibility with UL and NEMA enclosure requirements.
Best suited for large feeders in switchgear, motor control centers, and robust distribution panels, particularly where high current, three-pole protection, and bottom-feed layouts are standard. It’s ideal for facilities needing reliable nuisance-trip resistance and compatibility with UL-listed safety standards, while enabling future expansion with auxiliary contact options.
The device is UL Listed and supports NEMA 1, 3R, 4, and 12 enclosure ratings, which broadens installation options from indoor panels to more demanding environments. This combination helps meet widely adopted electrical safety codes and reduces the need for additional certification steps during project approvals.
With its high-current capacity, robust fusible protection, and optional ground fault signaling, the switch minimizes nuisance trips and simplifies fault isolation. The bottom-feed design and availability of auxiliary/provisions enable easier diagnostics and potential future automation integrations, delivering a lower life-cycle cost and higher overall plant reliability.
