Eaton CB2533T120480PC Pringle bolted pressure contact switch - UL Listed
Part Number: CB2533T120480PC
Quick Summary
Eaton pringle bolted pressure contact switch provides high-current protection for large motor drives in industrial facilities. Operators often face unreliable fault isolation and inconsistent trip timing when protection devices are underspecified or difficult to service. UL Listed construction pairs with NEMA ratings 1, 3R, 4, and 12 to endure demanding environments and maintain uptime. With a 2500A amperage rating and 480V system capability, it supports robust protection schemes while simplifying maintenance planning. A 120V control voltage and capacitor trip device enable fast, selective tripping and reduce total cost of ownership.

FAQs
When integrating CB2533T120480PC, consider its top feed fuse configuration and 17 x 28 x 28 in footprint, which influence enclosure layout and cable routing. The unit weighs 205 lb, requiring appropriate lifting and mounting provisions. Ensure compatible three-pole wiring, 120V control wiring, and a 480V system environment to maintain performance and safe maintenance access.
Key specs include a 2500A amperage rating, 480V system voltage, 480V maximum, three-pole, three-wire configuration, fusible protection, and a 120V control voltage. It features a capacitor trip device for precise protection timing and a single-phase relay mechanism. UL Listed certification further supports reliability and compliance in demanding facilities.
Yes, the unit is designed for harsh environments, supported by NEMA ratings for enclosure protection such as 1, 3R, 4, and 12. UL Listed certification confirms safety and reliability. While not explicitly IP-rated, the NEMA enclosure ratings provide robust protection against dust, moisture, and incidental exposure common in manufacturing and processing facilities.
The CB2533T120480PC is UL Listed, which validates safety and performance under applicable electrical standards. It also carries NEMA-rated enclosure compatibility (1, 3R, 4, 12), indicating suitability for indoor and outdoor applications depending on the specific installation. Optional features such as ground fault and auxiliary provisions may be requested to meet site requirements.
The switch’s 2500A rating and capacitor trip device reduce nuisance trips and optimize protection coordination, potentially lowering downtime costs. Its sturdy 205 lb enclosure and reliable UL Listed build translate to longer service intervals and reduced maintenance frequency. The warranty terms (1 year from installation or 18 months from shipment) provide initial protection against defects and early-life failures.
