Eaton CB2033B120240G Pringle bolted pressure contact switch - UL Listed
Part Number: CB2033B120240G
Quick Summary
Eaton CB2033B120240G is a bolted pressure contact switch for high‑duty electrical distribution protection. The design addresses costly downtime caused by unreliable trip mechanisms and slow responses in critical facilities. UL Listed with robust NEMA enclosure ratings (NEMA 1, 3R, 4, 12) and optional protections such as ground-fault relay, single‑phase protection, and auxiliary contacts provide real-world reliability. In practice, engineers benefit from a 120 V control voltage and a 240 V system interface, enabling safer, faster integration and easier maintenance planning for switchgear assemblies.

Eaton Specification Sheet - CB2033B120240G
High amperage and robust protection enable single-device service for large feeders, reducing hardware count and maintenance overhead. Feature → Business Impact → Application: 2000 A amperage rating paired with 240 V system voltage supports main feeder protection in commercial and industrial switchgear, minimizing downstream outages in data centers and manufacturing lines. Feature → Business Impact → Application: 120 V control voltage simplifies integration with existing control circuits and control power transformers, improving reliability of control interlocks and reducing wiring complexity in panel assemblies. Feature → Business Impact → Application: Three‑pole, bottom feed and fusible configuration streamlines wiring and enhances fault isolation, improving installation efficiency during panel upgrades and new installations. Feature → Business Impact → Application: Ground fault with control power transformer and optional ground fault relay enhances protection against ground faults, lowering risk of arc-flash events and unplanned downtime. Feature → Business Impact → Application: Optional single‑phase protection, auxiliary contact provisions, and Kirk provisions provide configuration flexibility for ISO and NEC compliance, enabling scalable protection schemes in industrial plants. Feature → Business Impact → Application: UL Listed with NEMA 1/3R/4/12 enclosure ratings delivers rugged performance in harsh environments, supporting long service life, easier procurement, and lower total cost of ownership for switchgear. Industry context: bolted pressure contact switches remain preferred for high‑reliability, low-maintenance protection in power distribution and automation environments, where downtime translates to significant cost and safety implications.
