Eaton CB2533B1204805 bolted pressure contact switch - UL
Part Number: CB2533B1204805
Quick Summary
Eaton CB2533B1204805 bolted pressure contact switch is designed for high-current switching in industrial power distribution. In demanding facilities, unreliable protection can cause nuisance trips, downtime, and damage to feeders and motors. UL Listed and NEMA ratings 1, 3R, 4, and 12 provide proven protection across indoor and rugged environments. Optional ground fault relay, single-phase protection, and auxiliary contact provisions extend safety and control for complex switchgear assemblies. With 2500 A at 120 V control and 480 V system voltage, the three-pole, bottom-feed design aligns with modern plant wiring while delivering robust protection and easy integration into existing safety schemes.
