Eaton CB1633T120208PA9C Pringle bolted switch - UL Listed
Part Number: CB1633T120208PA9C
Quick Summary
CB1633T120208PA9C is a high-capacity bolted pressure contact switch designed for reliable protection in industrial switchgear. Engineers often struggle with reliable trip timing and nuisance trips under peak loads. UL Listed certification supports regulatory compliance, while broad NEMA ratings—NEMA 1, 3R, 4 and 12—provide installation flexibility for rugged environments. Top-feed, three-pole configurations with fusible protection align with Eaton switching devices and simplify integration in control panels. This combination delivers predictable operation, reduced maintenance intervals, and a clear path to compliance within industrial automation projects.
