Eaton CB2033B120480AX5 Pringle pressure switch - UL Listed

High-current switching capability enables direct switching of large motors and feeders, reducing the number of devices required in a feed path. The 2000A amperage rating with a 480V system voltage, coupled with a 120V control circuit, translates to fewer interconnections and shorter commissioning times in MCCs and power distribution panels. This results in lower installation costs and improved system reliability across critical loads. The pringle bolted pressure contact design uses an electrical trip with charge-before-close mechanism, ensuring a known, pre-charged state before closing contacts, which minimizes arcing and improves safety during startups and fault events. The three-pole, 1NO-1NC contact arrangement supports precise control of line and load circuits, enhancing protection strategy and coordination with downstream devices. Bottom feed, three-wire configuration simplifies wiring and reduces panel depth, while supporting clean integration with existing harnesses and field wiring. Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions offer tailored protection for specific equipment, reducing retrofit costs and downtime. The enclosure ratings—NEMA 1, 3R, 4, 12—and UL Listed certification help ensure compliance with industrial safety standards and streamline audits, even in mixed indoor/outdoor installations. With Eaton’s warranty and service support, the switch delivers dependable lifecycle performance in demanding environments.
