Quick Summary

Eaton CB2033T120208GRAX pressure contact switch provides high-capacity single-phase protection for large industrial panels. Engineers often wrestle with nuisance trips and inconsistent protection, leading to downtime; this model uses a capacitor trip device (SPVR) and a top-feed design to improve reliability. UL Listed certification and NEMA 1, 3R, 4, 12 ratings support safe operation across diverse environments, while the three-pole, fusible configuration simplifies wiring and protection coordination. Optional Ground Fault Relay, Blown Fuse Detection, auxiliary contact provisions, and Kirk provisions widen integration with existing switchgear. This combination translates to reduced maintenance costs and faster commissioning for power distribution and machine-control applications.
