Eaton CB1233B120480AR Pressure Contact Switch - UL Listed
Part Number: CB1233B120480AR
Quick Summary
Eaton CB1233B120480AR is a pressure contact switch designed for protective switching in switchgear and motor control centers. When protection modules fail to trip on time, downtime and expensive outages interrupt critical production lines. UL Listed certification, broad enclosure compatibility with NEMA ratings 1, 3R, 4 and 12, and fusible protection help ensure safety, reliability, and regulatory compliance. Bottom-feed design with 120 V control and 480 V system voltage simplifies wiring in compact panels, while three-pole operation supports robust three-phase protection. Optional Ground Fault Relay, Blown Fuse Detection, and auxiliary contacts give flexible protection logic for modern plant protection schemes. Together, these features translate to reduced maintenance costs, faster recovery, and safer, more reliable operation in industrial facilities.
