Eaton Specification Sheet - CB3033B120208RARCT
Three-pole electrical trip with capacitor trip device (SPVR) provides precise protection timing and fast fault clearing. This reduces nuisance trips, minimizes wear on contactors, and lowers maintenance costs for high‑current motor circuits. Application: ideal for heavy-duty machine feeders and distribution panels in manufacturing plants. Bottom feed and fusible configuration simplify wiring and installation, reducing panel depth requirements and increasing protection reliability in tight spaces. The design supports straightforward retrofits and compatibility with existing Eaton switching devices, enabling more flexible panel design and maintenance planning. UL Listed certification and NEMA ratings 1, 3R, 4, 12 deliver environmental resilience and regulatory compliance, supporting safe operation in diverse facilities. Optional Ground Fault Relay, Blown Fuse Detection, and auxiliary contact provisions enhance diagnostics, control options, and integration with monitoring systems. This combination translates to higher overall equipment effectiveness (OEE) and reduced lifecycle costs for industrial automation projects.

FAQs
The CB3033B120208RARCT uses a bottom-feeding, three-pole configuration with fusible protection. Plan for a bottom-feed wiring route, mount in a compatible enclosure (UL Listed with NEMA 1, 3R, 4, 12), and connect the SPVR circuit as specified in the Eaton datasheet. Optional provisions for auxiliary contacts and ground fault relays can be added during installation to support diagnostics and expanded control logic.
Key specs include a 3000A amperage rating, 120 V control voltage, and 208 V system voltage with a fusible protection scheme. The device is a three-pole, three-wire switch designed for single-phase protection with a capacitor trip device. Ensure compatibility with your enclosure type (UL Listed) and verify NEMA ratings 1, 3R, 4, 12 for your environment.
Yes, due to its NEMA compatibility (1, 3R, 4, 12) and UL Listing, it is designed for a range of industrial settings. The bottom-feed design and fusible protection provide robust protection in panels, control rooms, and outdoor or dusty environments, while the SPVR mechanism ensures reliable tripping behavior essential for motor protection.
The device is UL Listed and supports NEMA 1, 3R, 4, and 12 enclosure ratings. Optional features like Ground Fault Relay and auxiliary contacts can aid regulatory compliance and diagnostic capabilities. This combination helps ensure safe operation, easy procurement, and standardization across Eaton switching devices in the plant.
