Eaton CB1633T120480AX6 Pringle Bolted Pressure Switch - UL
Part Number: CB1633T120480AX6
Quick Summary
Eaton CB1633T120480AX6 Pringle bolted pressure contact switch provides rugged, high-capacity protection for industrial power distribution. Designers and maintenance teams often battle complex protection schemes that trigger nuisance trips or slow responses; this device delivers fast, reliable protection with a charge-before-close mechanism. It carries UL Listed certification and is compatible with NEMA 1, 3R, 4, and 12 enclosures, supporting a variety of plant environments. Engineered for motor control centers and main feeders, it supports 1600A at 480V with top-feed and three-pole protection, plus 120V control voltage. Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, auxiliary contacts, and Kirk Provisions enhance safety and coordination. The combination of robust construction, standard components, and Eaton support minimizes downtime and lowers total cost of ownership.

Eaton Specification Sheet - CB1633T120480AX6
High-current capability of 1600A at 480V enables direct protection for large motor loads, reducing the need for upstream devices and simplifying protection coordination. This translates to fewer nuisance trips and faster fault clearance in demanding industrial environments. Application: motor control centers (MCCs) and main feeders in heavy-duty switchgear. Top-feed fuse configuration and three-pole design improve wiring ergonomics and reliability, making field installation faster and less error-prone. Application: panel assemblies in manufacturing and processing facilities. UL Listed certification and compatibility with NEMA 1, 3R, 4, and 12 enclosures simplify regulatory approvals and enclosure selection. Application: robust, compliant industrial installations. Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Auxiliary Contacts, and Kirk Provisions offer enhanced safety, monitoring, and control integration. Application: risk mitigation and smarter protection strategies. Charge-before-close operation reduces arc exposure and wear, extending contact life in high-load switching. Application: maintenance-wide reliability and reduced replacement cycles.
