Eaton CB2033B120480ALC Bolted Pressure Switch - UL Listed
Part Number: CB2033B120480ALC
Quick Summary
Eaton CB2033B120480ALC bolted pressure contact switch protects heavy-duty distribution systems in industrial switchgear. Nuisance trips and inconsistent fault protection can halt production; this device addresses that with a robust three-pole, fusible design. UL Listed certification ensures electrical safety compliance, and the enclosure supports broad environments with NEMA ratings including 1, 3R, 4, and 12. With bottom-feed wiring and optional protective accessories such as ground fault relay, auxiliary contact provisions, Kirk provisions, and blown fuse detection, it integrates smoothly into existing panels, streamlining installation and maintenance while delivering reliable protection and long-term operational efficiency. This makes it a practical choice for plant-wide switchgear retrofits.
