Eaton CB3033B120208GAX Pringle bolted pressure switch - UL
Part Number: CB3033B120208GAX
Quick Summary
Eaton CB3033B120208GAX is a bolted pressure contact switch designed for primary protection in industrial power distribution. Operators and engineers often wrestle with nuisance trips and unreliable fault detection under heavy loads, which disrupt production and increase maintenance costs. UL Listed certification, plus NEMA ratings for enclosures (NEMA 1, 3R, 4, and 12), and fusible protection, provide clear compliance and safety advantages. Designed for three-pole, three-wire configurations with bottom feed, it simplifies wiring and integration with switchgear and motor control centers. In practice, this translates to faster installations, better outage protection, and reduced spare-part inventory.
