Eaton CB1233T120480KG14 Pringle bolted pressure switch UL
Part Number: CB1233T120480KG14
Quick Summary
Eaton CB1233T120480KG14 is a bolted pressure contact switch designed for machine safety interlock in heavy industrial panels. Manufacturers often struggle with reliable ground fault protection, accurate top-feed wiring, and smooth integration with control power transformers. UL listed with broad NEMA ratings—NEMA 1, 3R, 4, and 12—provides confidence for harsh environments and critical safety duties. In practice, this device supports faster installation, reduced downtime, and reliable protection across 480 V systems and 120 V control circuits. This combination strengthens Eaton's switching devices portfolio, delivering a robust, scalable solution for complex panel builds and retrofit projects.
