Eaton Specification Sheet - CB1233T120480RAX
Capacitor trip device (SPVR) with a charge-before-close improves fault discrimination and minimizes inrush during switching. Business impact: reduces nuisance trips, extends motor life, and improves protection coordination with upstream devices. Application: ideal for large motor feeders in manufacturing and processing facilities where reliable protection and fast clearance are essential. Top-feed, three-pole design supports high-current switching and straightforward wiring in 480V distribution panels, delivering dependable protection for demanding loads up to 1200A with a 120V control circuit. This configuration reduces installation time and enhances panel density, while enabling easier integration with existing protection schemes and spare-part alignment for long-term maintenance.

FAQs
Installation begins with confirming panel clearance for a three-pole, top-feed device rated at 1200A. Mount the switch in the designated compartment, align the three incoming lines to the three terminals, and connect the 120V control circuit. Ensure compliance with UL Listed practices and Kirk provisions where applicable. Verify phase sequencing and perform a functional test before commissioning.
The SPVR capacitor trip device provides a controlled, capacitor-assisted trip action that improves discrimination during fault conditions. This reduces nuisance trips, minimizes motor and drive stress, and shortens disturbance durations. For engineers, the result is better system uptime, easier fault analysis, and more predictable protection coordination in 480V, high-current feeders.
The unit is UL Listed and supports NEMA-rated enclosures: 1, 3R, 4, and 12, offering robust protection against dust, moisture, and corrosion in challenging environments. This makes it suitable for manufacturing floors, outdoor-rated installations, and damp/dirty conditions found in process plants, while maintaining reliable protection for critical loads.
Yes. Catalog Notes explicitly state that OPTIONAL Ground Fault Relay and Blown Fuse Detection are AVAILABLE. Auxiliary Contact Provisions and Kirk provisions can be incorporated to expand monitoring, signaling, and integration with plant-wide protection schemes, enabling enhanced safety, fault detection, and easier integration with supervisory controls.
Typical applications include switchgear panels and feeders in process industries, data centers, and large manufacturing facilities where high-current, three-wire, three-pole protection is required. The 480V system voltage, 1200A amperage rating, and top-feed design make it well-suited for motor feeders, critical power distribution, and scenarios requiring rapid fault clearance and robust enclosure protection.
