Quick Summary

CB2033T120208GR bolted pressure contact switch is a high-current protection relay for motor loads in industrial control panels. Engineers often contend with nuisance trips and downtime that erode productivity and increase maintenance costs. UL Listed safety certification and NEMA compatibility with enclosures for 1, 3R, 4, and 12 streamline plant approvals. This switch enables reliable ground-fault protection, top-feed wiring, and capacitor-trip performance that reduces unplanned outages. With a 2000A amperage rating and 120 V control voltage (208 V system), it supports demanding feeders and motor circuits, while optional Ground Fault Relay and auxiliary provisions allow tailored protection schemes. Designed for three-pole top-feed installations, it uses a charge-before-close mechanism with SPVR to improve control reliability and lifecycle ROI.
