Eaton Specification Sheet - CB1233B120208RARCT
SPVR capacitor trip device provides coordinated protection for single-phase circuits, reducing nuisance trips and improving reliability in motors and lighting feeds. This feature translates to predictable switching behavior and minimized downtime in complex panel assemblies. The three-pole, bottom-feed design supports a fusible configuration capable of handling up to 1200A at 208V, delivering robust fault current handling and straightforward wiring in large panelboards. UL Listed certification underpins regulatory compliance and procurement confidence, while compatibility with NEMA 1, 3R, 4, and 12 enclosures ensures dependable operation in a range of industrial environments. Optional Ground Fault Relay, Blown Fuse Detection, Auxiliary Contact Provisions, and Kirk Provisions enable tailored protection schemes without added component complexity. A built-in control power transformer simplifies on-site commissioning and reduces auxiliary hardware needs, supporting faster installation and fewer field issues. The overall heavy-duty construction, including a 16 in depth, 24 in width, and 32 in height footprint with a 200 lb weight, makes this solution ideal for bolted-primary protection in switchgear corridors and MCCs.

FAQs
To install CB1233B120208RARCT, verify system voltage and amperage ratings (208 V, 1200 A), confirm bottom-feed fuse configuration, and mount in a suitable enclosure. Connect the control power transformer if required, and ensure alignment with three-pole wiring. Use proper torque on lugs and observe clearance to prevent overheating. The SPVR device should be wired per the schematic in the Eaton notes.
SPVR stands for single-phase voltage relay with capacitor trip device. It provides a controlled, capacitor-assisted trip to improve coordination and reduce nuisance trips in single-phase feeders. This leads to more stable protection in MCCs and panelboards, especially during inrush events or brief voltage sags, enhancing overall reliability and uptime.
Yes. The unit is rated for 208 V system voltage with a 120 V control voltage, and it supports a 1200 A amperage rating. This makes it suitable for large switchgear and MCC applications where high-current protection is required, while keeping control circuits within standard low-voltage ranges.
The CB1233B120208RARCT is UL Listed and designed for NEMA-rated environments, specifically supporting NEMA 1, 3R, 4, and 12 enclosures. This makes it suitable for indoor industrial facilities, outdoor equipment with weather protection, and harsh manufacturing environments where robust protection and reliable operation are critical.
The combination of a SPVR capacitor trip, fusible protection, and bottom-feed three-pole design reduces nuisance trips and minimizes unplanned downtime. The UL Listed certification and enclosure compatibility simplify procurement and commissioning, while the auxiliary provisions and ground-fault options enable tailored protection schemes. Overall, expect lower maintenance costs and faster return on investment due to improved reliability and simplified installation.
