Eaton CB1233T120480KRAR Bolted Pressure Contact - UL
Part Number: CB1233T120480KRAR
Quick Summary
The Eaton CB1233T120480KRAR is a bolted pressure contact switch for high-capacity motor protection in industrial power distribution. In the field, downtime and wiring errors drive maintenance costs, so this SPVR-equipped device reduces service interruptions. UL Listed certification is included, and it supports NEMA 1, 3R, 4, and 12 enclosures for versatile installations. Optional features such as Ground Fault Relay, Blown Fuse Detection, and Auxiliary contacts simplify protection strategies and spare-part planning. By supporting top-feed fuse configurations and three-pole operation, it integrates smoothly with existing Eaton or third-party switchgear, reducing installation time and risk. This translates to faster commissioning and fewer field ambiguities during panel upgrades.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature SPVR is single-phase voltage relay with capacitor trip device, interlock, and three normally off lights that trip the switch. Business Impact This combination delivers tighter protection coordination, decreases nuisance trips, and improves safety during fault events in motor feeders. Application In switchgear assemblies and motor control panels where precise trip sequencing is critical. Feature Top-feed fuse configuration and three-pole design support high-current distribution with simplified wiring and reliable fault isolation. Business Impact This minimizes wiring errors, reduces panel footprint, and accelerates commissioning in new builds or upgrades. Application Suitable for heavy-duty industrial environments where 480 V system voltage and 1200 A ratings are common. Feature NEMA 1, NEMA 3R, NEMA 4, NEMA 12 compatibility ensures enclosure versatility. Business Impact This enables installation in a wide range of environments, from clean rooms to harsh production floors. Application Ideal for rugged controller enclosures and outdoor-rated switchgear with UL-listed protection. Feature Optional Ground Fault Relay, Blown Fuse Detection, Kirk Provisions, and Auxiliary Contact Provisions provide flexible protection and control options. Business Impact This simplifies compliance, spare-part planning, and integration with existing control circuits. Application Enables tailored safety schemes in legacy and modern automation architectures. Feature Top-feed, no-ground-fault design and three-wire configuration support straightforward installation. Business Impact This reduces commissioning time and ensures consistent performance across multiple panels. Application Fits into existing Eaton or third-party systems with reduced risk and faster upgrades.
