Eaton CB2533B120480PAX7C UL
Part Number: CB2533B120480PAX7C
Quick Summary
CB2533B120480PAX7C is an Eaton bolted pressure contact switch for high-capacity electrical protection. Engineers often struggle with reliable single-phase protection and precise capacitor-trip operation in crowded switchgear. UL Listed certification and strong enclosure compatibility with NEMA 1, 3R, 4 and 12 provide safety and environmental resilience. For procurement teams, the combination of a 2500A rating, 120V control voltage, and 480V system voltage with three-pole operation translates to predictable installation and longer service life. This model also supports optional Ground Fault Relay, auxiliary contacts, and Kirk provisions to tailor protection and monitoring to your plant.
