Eaton CB1633T1204807 Pringle bolted pressure contact switch - UL Listed

1600A amperage rating paired with a 480V system voltage enables direct protection for large motors and feeders, reducing the need for multiple upstream devices and enabling more compact, cost-efficient panel designs. This translates to lower installation costs and improved fault isolation, especially in high-demand production lines where uptime matters. Top-feed, fusible configuration with no ground fault reduces nuisance trips and arc-flash exposure, improving overall safety and reliability in demanding environments like automotive, chemical, and metals processing. The 2 NO-2 NC contact configuration offers flexible control circuits for interlocks, alarms, and remote signaling, supporting scalable automation strategies while keeping wiring simple and testable. The charge-before-close mechanism enhances sequence control, minimizing false trips and extending equipment life, which drives measurable reductions in maintenance and replacement costs. NEMA 1, 3R, 4, and 12 compatibility ensures operation in a wide range of enclosures and environments, from clean rooms to outdoors when protected. Optional features such as Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, and Auxiliary Contact Provisions can be added without replacing the switch, enabling tailored protection schemes as plant requirements evolve. Physical dimensions and weight—16 in length, 28 in height, 24 in width, and 180 lb—facilitate accurate space planning and mounting in established electrical rooms or switchgear bays.
