Eaton CB1633B120480GRAX5 Pringle bolted pressure switch - UL

Feature is a bolted pressure contact switch with a three-pole, 1NO-1NC configuration that delivers robust overcurrent and ground-fault protection. Business Impact: reduces unplanned downtime and extends motor life by preventing fault conditions from propagating through the electrical system. Application: ideal for large industrial panels and switchgear in harsh environments where bottom-feed, fusible protection is required. Feature SPVR single-phase relay with capacitor trip device improves trip accuracy and minimizes nuisance tripping, translating into higher plant availability in continuous-process operations. Feature Bottom feed and ground fault with control transformer simplifies wiring, reduces assembly time, and supports compliant control power distribution. Feature 1600A amperage rating and 480V system voltage provide scalable protection for high-capacity motor loads while maintaining compatibility with standard 120V control circuits. Feature NEMA 1, 3R, 4, 12 ratings ensure resilience in dusty, wet, and corrosive environments, easing installation in diverse facilities. Feature Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contacts allow tailored protection schemes without replacing the base unit. The three-wire, three-pole design aligns with common industrial feeder architectures, enabling straightforward integration with existing switchgear. In practice, technicians appreciate the compact documentation and Eaton’s catalog notes for Kirk provisions, auxiliary options, and installation guidance, which speed commissioning and simplify ongoing maintenance.
