Eaton CB2033T120208GRA Bolted pressure contact switch - UL
Part Number: CB2033T120208GRA
Quick Summary
Eaton pringle bolted pressure contact switch protects three-pole power distribution in industrial facilities. Nuisance trips and slow fault detection hamper uptime, but this unit’s capacitor trip device (SPVR) and optional ground fault relay address those issues. UL Listed certification supports safety compliance, with NEMA 1, 3R, 4, and 12 ratings enable versatile indoor and harsh-environment installations. In practice, it integrates with Eaton Switching Devices ecosystems and supports top-fed, three-wire configurations for scalable protection. The result is improved reliability, faster fault discrimination, and simpler maintenance, delivering measurable reductions in downtime, service calls, and energy waste while meeting regulatory requirements. This makes it a compelling choice for plant engineers seeking durable protection without compromising installation efficiency.
