Eaton Specification Sheet - CB1233T120480RCT
Bolted pressure contact switch with a capacitor trip device (SPVR) delivers fast, predictable fault clearing, reducing downstream damage and unplanned downtime. This combination translates to higher line availability in feeders and MCCs, especially where rapid isolation of single-phase faults is critical. The device is tailored for 480 V systems and supports 1200 A loads with a top-feed, fusible configuration, making integration with existing switchgear straightforward. High-current capability and clear ratings support predictable protection coordination; the unit is rated for 1200 A with a 480 V system voltage and a 120 V control voltage, enabling direct interlock with common control transformers. Its three-pole construction and three-wire topology simplify wiring while aligning with standard electrical layouts, and the fusible protection aligns with typical utility and OEM practices, reducing the need for additional protection devices. Compatibility and certifications matter for compliance-minded projects; UL Listed certification and NEMA ratings (NEMA 1, 3R, 4, 12) ensure suitability across environments. Optional Ground Fault Relay and Blown Fuse Detection extend protection without cabinet redesign, and auxiliary contact provisions provide status feedback for centralized monitoring. Installation advantages drive real-world value: top-feed fuse configuration minimizes wiring complexity and speeds assembly in new builds or upgrades, while add-on options such as auxiliary contacts enable signaling with minimal intrusion. Warranty and support reduce lifecycle risk, with Eaton’s policy and available catalog notes enabling predictable maintenance, improved ROI through reduced downtime, easier service, and faster commissioning in manufacturing settings.

FAQs
CB1233T120480RCT uses a top-feed, three-pole, fusible configuration for straightforward panel integration. Ensure the 1200 A rating aligns with your bus and conductor sizing, connect the 120 V control circuit, and leverage the optional Ground Fault Relay or Blown Fuse Detection where required. Use the auxiliary contact provisions for signaling and diagnostics to support centralized monitoring.
Key ratings include 1200 A amperage, 480 V system voltage (and 480 V voltage max), 120 V control voltage, three-pole, three-wire configuration, and fusible protection. The device is UL Listed and supports NEMA 1, 3R, 4, and 12 enclosures. These specs ensure compatibility with typical industrial switchgear and panel budgets.
Yes. The CB1233T120480RCT is designed for 480 V systems with a top-feed and fusible protection. Its three-pole design and SPVR-enabled capacitor trip device accommodate single-phase protection needs in 480 V networks, while maintaining compatibility with standard control transformers and MCCs.
The switch carries UL Listed certification and supports multiple NEMA enclosure ratings (NEMA 1, 3R, 4, 12). These certifications help ensure electrical safety, regulatory compliance, and easier acceptance in regulated environments, reducing the risk of non-compliance during audits or inspections.
The SPVR-based trip with optional Ground Fault Relay and Blown Fuse Detection minimizes nuisance trips and downtime while simplifying maintenance planning. High reliability and standardization across MCCs improve commissioning speed, reduce spare parts, and lower total cost of ownership over the equipment lifecycle.
