Special features
Single-phase voltage relay with capacitor trip device (SPVR), interlock, BFD with no lights (trips switch)
High-current capability with a 1200A amperage rating enables this switch to handle large feeders and motor loads, reducing the need for multiple devices and simplifying panel design. Business impact: streamlined installations and a lower total cost of ownership in heavy-industrial environments. Application: power distribution panels and motor control centers where robust protection is required. The SPVR capacitor trip device provides a controlled single-phase protection sequence, delivering faster, more predictable trips and improving selectivity during faults. Business impact: minimized downtime and reduced risk of collateral damage to downstream equipment. Application: critical power feeds and distribution circuits in manufacturing lines. Interlock functionality and Blown Fuse Detection (BFD) with no lights enhance safety and maintenance efficiency by clearly signaling fault conditions without unnecessary alarms. Business impact: safer operation and lower maintenance costs. Application: compact, high-density switchgear where clear fault indication matters. Optional Ground Fault Relay and auxiliary contact provisions expand diagnostic and interlock capabilities, supporting advanced protection schemes and easier integration with PLCs. Business impact: improved fault isolation and enhanced automation compatibility. Application: data centers, chemical processing, and other facilities requiring precise fault detection. Top-feed configuration and a fusible design combined with NEMA-rated enclosures deliver installation flexibility in tight spaces and harsh environments. Business impact: faster commissioning and broader enclosure compatibility. Application: retrofit projects and new builds across industrial automation and electrical distribution systems.

FAQs

When retrofitting CB1233T120480KGRAX into existing switchgear, ensure a top-feed, three-pole configuration and fusible protection align with the panel’s bus arrangement. Verify enclosure compatibility with NEMA ratings (1, 3R, 4, 12) and plan for the SPVR capacitor trip device, interlock, and optional ground fault relay to match your protection strategy. Leave space for auxiliary contacts if required by your control scheme and confirm wiring aligns with the 120 V control circuit.
This model is rated for 1200A and 480V, making it suitable for large feeders and motor circuits. Its three-pole design and fusible protection provide robust interruption capability, while SPVR aids in controlled tripping. In practice, this reduces panel complexity, lowers wiring and component counts, and improves uptime in demanding manufacturing or processing environments.
Yes. The catalog notes show options for a Ground Fault Relay and Auxiliary Contact Provisions, enabling enhanced fault detection and control integration. This supports modern protection schemes and PLC-based monitoring, allowing quicker isolation of faults and easier integration with existing control architectures.
CB1233T120480KGRAX is UL Listed, ensuring compliance with recognized safety standards. Its top-feed, fusible three-pole design is compatible with multiple NEMA enclosure types, aiding regulatory compliance and installation flexibility in diverse industrial settings. Optional features like SPVR and ground fault protection further support compliance with stringent safety and protection requirements.
The product falls under Eaton’s warranty policy 25-000, offering one year from installation or eighteen months from shipment, whichever comes first. For maintenance, rely on the UL-listed robustness, optional diagnostics, and Kirk/warranty-covered provisions. Regular inspection of interlocks and trip devices helps maintain performance and extend service life in demanding environments.
