Eaton Specification Sheet - CB3033T120208RARCT
Feature → Business Impact → Application: The CB3033T120208RARCT delivers a 3000A amperage rating with a 208V system voltage and a 120V control voltage, enabling direct protection of large feeders in switchgear without needing additional intermediate devices, which reduces panel footprint and installation time. This translates to tangible efficiency gains in motor control centers and distribution panels, where downtime costs can be significant and reliability is paramount. Feature → Business Impact → Application: Three-pole, three-wire top-feed fuse configuration simplifies wiring and reduces fault pathways, resulting in faster commissioning and fewer wiring errors during installation in industrial plants. Feature → Business Impact → Application: SPVR with capacitor trip device and BFD three-light trip indicators provide quick fault diagnosis and reliable tripping, improving maintenance planning and operator confidence in automated protection across manufacturing lines. Feature → Business Impact → Application: Fusible protection complemented by NEMA ratings (1, 3R, 4, 12) ensures enclosure protection and environmental resilience, supporting compliance in harsh locations such as wash-down areas, outdoor panels, and dusty environments. Feature → Business Impact → Application: Optional Ground Fault Relay, Kirk provisions, and auxiliary contact provisions offer configurable protection schemes and expanded monitoring, enabling tailored protection for complex MCCs and multi-bus configurations. The result is improved protection accuracy, reduced surprise outages, and a clear path to ROI through extended equipment life and reduced repair costs.

FAQs
CB3033T120208RARCT uses a top-feed fuse configuration and three-pole wiring, simplifying conduit routing and reducing panel depth requirements. When planning installation, ensure compatible enclosure clearance, proper torque on lugs, and correct coordination with any optional ground fault relay or auxiliary contacts to maintain clear fault signals and reliable switching performance.
The switch is rated for 3000A with a 208V system voltage and a 120V control voltage. It supports fusible protection and provides a reliable SPVR capacitor trip. The device is designed for three-pole, three-wire operation and is suitable for harsh environments with its NEMA-compatible enclosure ratings (NEMA 1, 3R, 4, 12).
Yes. Its three-pole design, high current capability, SPVR trip, and top-feed configuration make it well-suited for motor control centers and large distribution panels. The SPVR mechanism offers fast fault clearance, while the fusible protection supports robust environmental and fault-condition resilience in MCC applications.
The CB3033T120208RARCT is UL Listed, confirming electrical safety compliance. It also carries NEMA ratings for enclosure compatibility (NEMA 1, 3R, 4, 12), ensuring appropriate protection in varied installation environments. Optional provisions like Ground Fault Relay and Auxiliary Contacts further support compliance with site-specific protection schemes.
Maintenance benefits stem from reliable SPVR operation, clear fault indication via BFD lights, and robust enclosure protection reducing environmental wear. ROI is driven by reduced downtime, longer equipment life from consistent protection, and simplified installation with top-feed wiring, which lowers commissioning costs and ongoing maintenance time.
