Eaton CB2033T120480KAX Pringle bolted pressure contact - UL
Part Number: CB2033T120480KAX
Quick Summary
Eaton pringle bolted pressure contact switch is designed for high‑current power distribution in industrial facilities, delivering reliable protection for large motor feeders. Operators struggle with nuisance trips, difficult maintenance access, and slow fault isolation; this device addresses those pains with robust interlock features and clear fault signaling. UL Listed and NEMA compatible (1, 3R, 4, 12), plus fusible protection, offer rugged performance across environments from dusty factories to washdown areas. By standardizing on this profile, maintenance teams benefit from reduced spare parts variety and faster troubleshooting, while procurement gains from a proven, field‑tested solution that scales with line loads and safety requirements.

FAQs
Install per Eaton catalog guidelines: mount in a compatible enclosure, wire three live leads to the three poles, and connect the 120 V control circuit to the control terminals. Ensure the top‑feed arrangement aligns with the enclosure bend radii and allows clear access for interlock components and future diagnostics.
Fuse sizing should coordinate with the expected short‑circuit current and upstream protective devices. Select a fusible configuration that provides rapid isolation for faults while preventing nuisance trips during normal startup. Verify coordination curves and clearance times to maintain safe, reliable operation at 480 V systems.
Yes. The device is listed for multiple NEMA ratings, offering enclosure compatibility from indoor dry spaces to washdown and harsh environments. For best results, pair with the correct enclosure gasketing and sealing per NEMA guidelines and follow installation practices to preserve protection classes.
Key certification is UL Listed, with NEMA compatibility across 1, 3R, 4, and 12. Compliance benefits include meeting industrial safety and reliability requirements, simplified documentation for audits, and alignment with OEM or end‑user safety programs. Always reference the Eaton specification sheet for verification of the latest certifications and features.
Regular maintenance should include inspection of interlock integrity, fuse condition, and protective relay diagnostics if equipped. ROI benefits arise from reduced downtime due to robust protection, extended switchgear life, and lower maintenance variability thanks to standardized Eaton components and optional diagnostic features.
