Eaton CB1233B120480GRAR7 Pressure contact switch - UL

Three-pole bolted pressure switch delivers a robust 1200 A current rating, ensuring reliable interruption across heavy-load equipment. This consolidation reduces maintenance complexity and minimizes unplanned downtime in motor-control centers. By combining timing coordination and mechanical reliability, it minimizes nuisance trips during startup surges and fault events, supporting continuous operations in conveyors, pumps, and grinders across manufacturing facilities. Capacitor trip device (SPVR) provides rapid, coordinated tripping, improving protection precision and extending equipment life. By reducing nuisance trips and miscoordination with upstream protection, maintenance costs drop and system reliability rises. Applications include switchgear assemblies, motor starters, and distribution panels where fast fault clearance matters for uptime. Ground fault capability with a control power transformer enhances personnel safety and equipment protection, meeting critical safety standards in harsh environments. The bottom-feed configuration simplifies field wiring and enclosure layout, enabling quicker installation and fewer wiring errors. These features support efficient commissioning in new builds and smoother upgrades to existing panels. UL Listed certification coupled with broad NEMA ratings (1, 3R, 4, 12) ensures compliance and enclosure compatibility across environments from damp plant floors to outdoor task areas. The 2 NO-2 NC contact configuration, along with 120 V control and 480 V system voltage, offers flexible integration into diverse control architectures. This combination reduces procurement risk and accelerates project approvals in regulated industries. Compatibility with optional Ground Fault Relay, Blown Fuse Detection, Auxiliary Contact Provisions, and Kirk provisions adds configurability without replacing the base unit. The fusible protection option provides clear fault segmentation for critical circuits, while bottom-feeding and bottom-feed fuse configurations streamline installation in tight spaces. Operators gain predictive maintenance insights and faster root-cause analysis through built-in protection features and diagnostic indicators.
