Eaton Specification Sheet - CB2033T120480GR
Feature: 2000A amperage rating enables direct protection of large feeders in distribution panels, reducing the need for multiple smaller devices and lowering hardware costs. Business Impact: Simplified protection architecture translates to faster maintenance and fewer failure points. Application: Suitable for industrial plants with high-current loads. Feature: Three-pole, three-wire configuration with ground fault option. Impact: ensures coordinated shutdown and safe isolation in demanding installations. Application: motor control centers and feeders. Feature: Capacitor trip device (SPVR) provides charge-before-close protection. Impact: minimizes nuisance trips by precise timing and improves selective coordination. Application: protection of large motors and sensitive loads. Feature: Top-feed/fuse configuration and optional extensions (Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, Auxiliary Contact Provisions available). Impact: flexible installation options and future-proof expansion. Application: retrofit in existing top-feed layouts. Feature: UL Listed device designed for NEMA-rated environments (NEMA 1, 3R, 4, 12) with rugged enclosure footprint. Impact: safer operation in harsh environments, reduced integration risk, and straightforward installation in control panels and switchgear. Warranty coverage complements ongoing maintenance and service needs.

FAQs
Begin by verifying the top-feed orientation and fuse configuration described for this unit. Mount the switch securely in a compatible enclosure, connect three wires per the three-pole, three-wire design, and install any optional ground fault or auxiliary contacts as required. Ensure clear labeling and adherence to UL safety guidelines during commissioning.
The SPVR provides a capacitor-assisted trip that improves timing precision for fault detection, reducing nuisance trips while maintaining fast, reliable protection for large motors and feeders. This yields improved protection coordination, lower downtime, and fewer false alarms in high-current applications.
Yes. With a 2000A rating, three-pole, three-wire configuration, and fusible protection for 480V systems, it is well-suited for MCCs and distribution panels in demanding industrial environments. The device supports top-feed installation and integrates with ground fault protection options for enhanced safety.
The CB2033T120480GR carries UL Listed certification, validating electrical safety and reliability for industrial use. It is designed to operate within NEMA-rated enclosures (NEMA 1, 3R, 4, 12) to support safe installation across common panel and outdoor environments.
Warranty terms follow Eaton policy: one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, inspect fuse status, SPVR components, and connections during routine panel checks to sustain performance and minimize unplanned downtime.
